ON-FARM INPUTS PREPARATION METHODS AND
PROTOCOLS
In natural farming, on-farm inputs are prepared using locally available, natural,
and organic materials to enhance soil fertility, manage pests, and promote plant growth
without relying on synthetic chemicals. Below is a concise overview of the different types
of on-farm inputs commonly used in natural farming, based on principles like those of
Zero Budget Natural Farming (ZBNF) and other organic practices.
On-farm made Natural Farming bio-inputs like Jeevamrut, Beejamrut, etc are
derived from natural resources like plant and animal materials. They play a crucial role
in promoting soil health, enhancing plant growth, and reducing reliance on externally
purchased synthetic chemical inputs. These NF bio-inputs are rich in beneficial microbes,
enzymes, and organic compounds, supporting nutrient cycling, pest management, and
soil rejuvenation, making them vital for sustainable agricultural practices.
Preparing on-farm inputs is a critical aspect of natural farming, as it allows
farmers to produce their own resources like compost, biofertilizers, biopesticides, and
seed treatments using locally available materials.

EXERCISE NO. 5
STUDIES IN GREEN MANURING IN-SITU AND GREEN LEAF
MANURING
Introduction to Green Manuring
Green manuring is a sustainable agricultural practice that involves incorporating
undecomposed green plant tissue into the soil to improve its physical, chemical, and
biological properties. This practice enhances soil fertility, reduces reliance on synthetic
fertilizers, and promotes environmental sustainability. There are two primary types of
green manuring: in-situ green manuring and green leaf manuring.
In-Situ Green Manuring
Definition
In-situ green manuring refers to growing green manure crops directly in the field where
the main crop will be planted. These crops are then incorporated into the soil, typically
by ploughing or tilling, before the main crop is sown.
Benefits of In-Situ Green Manuring
• Improved Soil Structure: The roots of green manure crops help to break up
compacted soil, improving aeration and water infiltration. The organic matter
added to the soil enhances its structure, making it more friable and easier to work.
• Enhanced Soil Fertility: Green manure crops fix atmospheric nitrogen through
symbiotic relationships with bacteria in their root nodules. When incorporated
into the soil, this nitrogen becomes available to subsequent crops. They also help
in solubilizing unavailable forms of phosphorus and potassium.
• Weed Suppression: A dense stand of green manure crops can suppress weed
growth by competing for resources such as sunlight, water, and nutrients.
• Reduced Soil Erosion: The cover provided by green manure crops protects the
soil from wind and water erosion, conserving topsoil and preventing nutrient loss.
• Increased Soil Organic Matter: The incorporation of green manure adds organic
matter to the soil, which improves its water-holding capacity, nutrient retention,
and overall soil health.
• Beneficial Microbe Activity: Green manuring promotes the growth and activity
of beneficial soil microorganisms, such as bacteria and fungi, which play a crucial
role in nutrient cycling and disease suppression.
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
Methods of In-Situ Green Manuring
1. Growing Green Manure Crops Before the Main Crop: This involves planting
a green manure crop after harvesting the previous main crop and allowing it to
grow for a specific period before incorporating it into the soil.
2. Intercropping Green Manure Crops with the Main Crop: Green manure crops
can be intercropped with the main crop, either in rows or as a cover crop between
rows. The green manure crop is then incorporated into the soil after the main crop
is harvested or at a suitable stage of growth.
3. Relay Cropping Green Manure Crops: This involves planting the green
manure crop before harvesting the main crop, allowing it to establish before the
main crop is removed. The green manure crop then continues to grow and is later
incorporated into the soil.
Suitable Crops for In-Situ Green Manuring
• Legumes: Legumes such as cowpea (Vigna unguiculata), sunn hemp (Crotalaria
juncea), dhaincha (Sesbania aculeata), and cluster bean (Cyamopsis
tetragonoloba) are excellent green manure crops due to their ability to fix
atmospheric nitrogen.
• Non-Legumes: Non-legumes such as mustard (Brassica juncea), buckwheat
(Fagopyrum esculentum), and rye (Secale cereale) can also be used as green
manure crops. They are effective at scavenging nutrients from the soil and
improving soil structure.
Considerations for In-Situ Green Manuring
• Timing: The timing of planting and incorporating the green manure crop is
crucial. It should be planted early enough to allow sufficient growth before
incorporation, but not so late that it interferes with the planting of the main crop.
• Incorporation: The green manure crop should be incorporated into the soil when
it is succulent and easily decomposable. This is typically at the flowering stage.
• Moisture: Adequate soil moisture is essential for the decomposition of green
manure. If the soil is dry, irrigation may be necessary.
• Nutrient Management: The amount of nitrogen fixed by the green manure crop
depends on factors such as the species of crop, soil conditions, and management
practices. It is important to consider the nutrient requirements of the subsequent
crop and adjust fertilizer applications accordingly.
Green Leaf Manuring
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
Definition
Green leaf manuring involves collecting green leaves and twigs from trees, shrubs, and
other plants growing in nearby areas and incorporating them into the soil of cultivated
fields.
Benefits of Green Leaf Manuring
• Nutrient Enrichment: Green leaves are rich in essential plant nutrients such as
nitrogen, phosphorus, and potassium. When incorporated into the soil, these
nutrients are released slowly, providing a sustained supply to the crop.
• Improved Soil Structure: The organic matter added through green leaf manuring
improves soil structure, increasing its water-holding capacity and aeration.
• Weed Suppression: A layer of green leaves on the soil surface can suppress weed
growth by blocking sunlight and preventing weed seeds from germinating.
• Reduced Soil Erosion: Green leaf manure acts as a mulch, protecting the soil
from wind and water erosion.
• Cost-Effective: Green leaf manuring can be a cost-effective alternative to
synthetic fertilizers, especially in areas where green leaves are readily available.
Methods of Green Leaf Manuring
1. Collection of Green Leaves: Green leaves and twigs are collected from trees,
shrubs, and other plants growing in nearby areas.
2. Application to the Field: The collected green leaves are spread evenly over the
field before plowing or tilling.
3. Incorporation into the Soil: The green leaves are incorporated into the soil by
plowing or tilling.
Suitable Sources of Green Leaves
• Leguminous Trees: Leguminous trees such as Gliricidia sepium, Leucaena
leucocephala, and Sesbania grandiflora are excellent sources of green leaves due
to their high nitrogen content.
• Non-Leguminous Trees: Non-leguminous trees such as neem (Azadirachta
indica), pongamia (Pongamia pinnata), and subabul (Leucaena leucocephala) can
also be used as sources of green leaves.
• Shrubs and Weeds: Certain shrubs and weeds can also be used as sources of
green leaves, provided they are not toxic or invasive.
Considerations for Green Leaf Manuring
• Availability: The availability of green leaves is a major consideration. It is
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
important to ensure that there is a sustainable supply of green leaves without
depleting natural resources.
• Decomposition: The rate of decomposition of green leaves depends on factors
such as the species of plant, the age of the leaves, and soil conditions. It is
important to choose leaves that decompose readily.
• Nutrient Content: The nutrient content of green leaves varies depending on the
species of plant and growing conditions. It is important to analyze the nutrient
content of the leaves to determine the appropriate application rate.
• Labor Requirements: Green leaf manuring can be labor-intensive, especially for
collection and application. It is important to consider the labor requirements when
planning to use this practice.

EXERCISE NO. 8
NUTRIENT MANAGEMENT IN NATURAL FARMING
Natural Farming, at its core, emphasizes working in harmony with nature to create a
self-sustaining agricultural ecosystem. Nutrient management in this context is not about
directly supplying nutrients to plants through synthetic fertilizers. Instead, it focuses on
creating a thriving soil ecosystem that naturally provides plants with the nutrients they
need. Key principles include:
• Soil as a Living Ecosystem: Recognizing the soil as a complex web of life,
including bacteria, fungi, earthworms, and other organisms, is fundamental.
These organisms play a crucial role in nutrient cycling and availability.
• Minimizing Soil Disturbance: Tillage disrupts the soil structure and harms
beneficial organisms. Natural Farming advocates for minimal or no-till practices
to preserve soil health.
• Cover Cropping and Mulching: These practices protect the soil surface,
suppress weeds, retain moisture, and add organic matter, which feeds soil
organisms.
• On-Farm Input Generation: Natural Farming promotes the use of locally
available resources to create nutrient-rich inputs, reducing reliance on external
sources.
• Diversity and Integration: Integrating diverse crops and livestock creates a more
resilient and balanced ecosystem, enhancing nutrient cycling.
Key Practices for Nutrient Management
Several key practices are employed in Natural Farming to manage nutrients effectively:
1. Enhancing Soil Health
• No-Till or Minimal Tillage: Avoiding or minimizing tillage preserves soil
structure, reduces erosion, and protects beneficial soil organisms.
• Cover Cropping: Planting cover crops between cash crops helps improve soil
fertility, suppress weeds, and prevent erosion. Leguminous cover crops, such as
clover or vetch, fix atmospheric nitrogen, enriching the soil.
• Mulching: Applying organic mulches, such as straw, leaves, or wood chips, helps
retain soil moisture, suppress weeds, regulate soil temperature, and add organic
matter as they decompose.
• Composting: Composting organic waste materials, such as crop residues, animal
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
manure, and kitchen scraps, creates a nutrient-rich soil amendment. Compost
improves soil structure, water-holding capacity, and nutrient availability.
2. On-Farm Input Preparation
Natural Farming emphasizes the use of locally available resources to create nutrient-rich
inputs. Some common preparations include:
• Jivamrita: A fermented microbial culture made from cow dung, cow urine,
jaggery, pulse flour, and soil. Jivamrita is applied to the soil to inoculate it with
beneficial microorganisms, which enhance nutrient availability and soil health.
• Beejamrita: A seed treatment made from cow dung, cow urine, lime, and soil.
Beejamrita protects seeds from soilborne pathogens and promotes germination
and seedling vigor.
• Ghanajivamrita: A solid form of Jivamrita, made by drying and powdering the
fermented mixture. Ghanajivamrita is applied to the soil as a slow-release
fertilizer.
• Neemastra: A biopesticide made from neem leaves, cow urine, and water.
Neemastra repels pests and protects crops from damage.
• Brahmastra: A biopesticide made from various plant extracts, such as neem,
datura, and custard apple leaves. Brahmastra is used to control a wider range of
pests.
• Agniastra: A biopesticide made from tobacco, green chilies, garlic, ginger, and
cow urine. Agniastra is used to control sucking pests.
3. Optimizing Nutrient Availability
• Crop Rotation: Rotating crops with different nutrient requirements helps prevent
nutrient depletion and improves soil health. Legumes, for example, fix nitrogen
in the soil, benefiting subsequent crops.
• Intercropping: Growing multiple crops together can enhance nutrient utilization
and suppress weeds. Companion planting, where specific crops are grown
together to benefit each other, is also a valuable strategy.
• Panchagavya: A fermented mixture of cow dung, cow urine, milk, curd, and
ghee. Panchagavya is used as a foliar spray to promote plant growth and enhance
nutrient uptake.
• Effective Microorganisms (EM): EM solutions contain a consortium of
beneficial microorganisms that can improve soil health, enhance nutrient
availability, and suppress plant diseases.
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
Benefits of Nutrient Management in Natural Farming
• Improved Soil Health: Natural Farming practices enhance soil structure, water-
holding capacity, and nutrient availability, leading to healthier and more fertile
soils.
• Reduced Reliance on External Inputs: By utilizing on-farm resources and
promoting natural nutrient cycling, Natural Farming minimizes the need for
synthetic fertilizers and pesticides.
• Enhanced Crop Quality: Crops grown using Natural Farming methods are often
more nutritious and have better flavour and shelf life.
• Increased Biodiversity: Natural Farming promotes biodiversity by creating a
more diverse and balanced ecosystem.
• Environmental Sustainability: Natural Farming practices reduce pollution,
conserve water, and promote carbon sequestration, contributing to a more
sustainable agricultural system.
• Climate Resilience: Healthy soils are more resilient to climate change impacts,
such as drought and flooding.
Challenges and Considerations
While Natural Farming offers numerous benefits, it also presents some challenges:
• Transition Period: Converting to Natural Farming may require a transition
period during which yields may initially decline.
• Knowledge and Skill: Successful implementation of Natural Farming requires a
good understanding of soil ecology, crop management, and on-farm input
preparation.
• Labor Intensive: Some Natural Farming practices, such as on-farm input
preparation, can be labor-intensive.
• Market Access: Access to markets that value and reward Natural Farming
products may be limited in some areas.
• Validation and Research: More research is needed to validate the effectiveness
of Natural Farming practices and to optimize them for different agro-ecological
zones.
Nutrient management in Natural Farming is a holistic approach that focuses on building
healthy soils and promoting natural nutrient cycling. By adopting practices such as no-
till farming, cover cropping, mulching, on-farm input preparation, and crop
diversification, farmers can create self-sustaining agricultural ecosystems that are both
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
productive and environmentally sustainable. While challenges exist, the benefits of
Natural Farming for soil health, crop quality, and environmental sustainability make it a
promising approach for the future of agriculture.

EXERCISE NO. 9 & 10
INSECT- PEST, AND DISEASE MANAGEMENT IN NATURAL
FARMING
Natural farming emphasizes sustainable, eco-friendly methods to manage insects,
pests, and diseases, focusing on maintaining ecological balance rather than eradicating
pests entirely. Below is a concise overview of strategies used in natural farming for insect,
pest, and disease management, based on principles like those in Zero Budget Natural
Farming (ZBNF) and organic practices:
Natural pest and disease management practices harness the ecological principles
such as biodiversity, food web, resilience, natural pest suppression, etc. to control pest
populations and disease incidence in a sustainable way, without relying on usage of inputs
such as pesticides, insecticides etc. A natural farming farm invites a wide range of
organisms, including beneficial insects, birds etc providing ecosystem services such as
pollination, natural pest control, maintenance of natural food cycle (predator-prey
relationships which reduces the likelihood of pest outbreaks). By fostering environmental
balance, promoting biodiversity, and ensuring long-term soil health, it aligns with the
principles of sustainable agriculture and Natural Farming.
A. Insect- pest management in natural farming
The ecological and economical problems of pests and pesticides in agriculture
gave rise to several eco-friendly innovative approaches which do not rely on the use of
chemical pesticides. These initiatives involved rediscovering traditional practices and
contemporary grass root innovations supplemented by strong scientific analysis mainly
supported by non-formal institutions like NGOs. Such innovations have begun to play an
important role in development sector. This trend has important implications both for
policy and practice.
The “Non Pesticidal Management” which emanates from collaborative work of
public institutions, civil society organizations and Farmers in Andhra Pradesh shows how
diverse players join hands to work in generating new knowledge and practice, can evolve
more sustainable models of development.
Several voluntary agencies, farmers from different regions and few scientists
from the subject area established that:
❖ Red Hairy Caterpillar
➢ This pest infests crops only on light red soils
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
➢ There is only one generation of moths that lay eggs producing the cater- pillars
which later hibernate in the soils. Adult moths appear in waves at the onset of the
monsoon. Controlling the pest necessitated the destruction of the early emergence
moths.
➢ The caterpillars are also attracted to some wild non-economical plants such as
Calotropis, wild castor, yellow cucumber.
➢ The later instars of larvae had dense red hairs all over the body, which prevents
pesticides from reaching the body of the insects as a result any pesticide sprayed
will not cause the mortality of the insect.
Package of practices were evolved based on the insect behaviour, which can
manage the RHC before it reaches damaging stages and proportions. Deep summer
ploughing exposes the resting pupae, adults of RHC. These insects are attracted to light-
community bonfires. Bonfires were used to attract the insects and kill them. Alternatively
light traps (electric bulbs or solar light) were also used. Trenches around the field to trap
migrating larvae by use of Calotropis and jatropha cuttings were found to be effective.
Neem sprays on the early instar larvae were found to be effective.
Pest is not a problem but a symptom. Disturbance in the ecological balance among
different components of crop ecosystem makes certain insects reach pest status. From
this perspective evolved the Non Pesticidal Management which is an “ecological
approach to pest management using knowledge and skill-based practices to prevent
insects from reaching damaging stages and damaging pro- portions by making best use
of local resources, natural processes and community action.
❖ Non Pesticidal Management is mainly based on:
➢ Understanding crop ecosystem and suitably modifying it by adopting suitable
cropping systems and crop production practices. The type of pests and their
behaviour differs with crop ecosystems. Similarly, the natural enemies’
composition also varies with the cropping systems.
➢ Understanding insect biology and behaviour and adopting suitable preventive
measures to reduce the pest numbers.
➢ Building farmers knowledge and skills in making the best use of local resources
and natural processes and community action. Natural ecological balance which
ensures that pests do not reach a critical number in the field that endangers the
yield. Nature can restore such a balance if it is not too much meddled with. Hence
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
no chemical pesticides/pesticide are applied to the crops. For an effective
communication to farmers about the concept effectively, and to differentiate from
Integrated Pest Management which believes that chemical pesticides can be safely
used and are essential as lost resort it is termed as “Non Pesticidal Management.
❖ Growing Healthy Plants from Good Quality Seed
• Seed Selection:
o Choose locally adapted seeds (traditional farmers’ varieties or improved
varieties from public sector institutions).
o Use a seed matrix to evaluate:
▪ Suitability for cropping patterns.
▪ Compatibility with soil types.
▪ Resistance to insect pests and diseases.
▪ Alignment with consumption preferences.
o Maintain seeds in seed banks for timely sowing and farmer control.
• Timely Sowing:
o Critical in rainfed areas to ensure crop health and productivity.
o Enables optimal use of monsoon rains and reduces pest/disease
vulnerability.
• Seed Treatment:
o Cow urine, ash, and asafoetida concoction: Protects against seed-borne
diseases (e.g., rice blast).
o Beejamrutha: Promotes soil microbial activity and eliminates seed-borne
pathogens.
o Milk dipping for brinjal seedlings: Dip seedlings or fingers in milk
before transplanting to prevent viral infections.
• Non-Pesticidal Management (NPM):
o Adopt practices to prevent insects from reaching damaging stages or
populations:
▪ Crop rotation and intercropping: Disrupt pest life cycles.
▪ Trap crops: Attract pests away from main crops (e.g., Calotropis
for Red Hairy Caterpillar).
▪ Biological control: Encourage natural predators (e.g., birds,
Trichogramma wasps) or use Bacillus thuringiensis (Bt).
▪ Physical barriers: Use nets, row covers, or sticky traps.
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
▪ Natural repellents: Apply neem-based solutions (e.g.,
Agninastra), wood ash, or cow dung ash.
▪ Field sanitation: Remove crop residues and weeds to reduce pest
habitats.
▪ Light/pheromone traps: Capture moths to prevent egg-laying
(e.g., Red Hairy Caterpillar moths).
▪ Hand-picking: Remove early instar larvae to prevent population
buildup.
❖ Reduce Stress
The pest and disease susceptibility increases with abiotic stress. Practices like
mulching will improve the soil moisture availability.
Fig. 1 Schematic representation of non-pesticidal management.
❖ Build Healthy Soils
Healthy soils lead to healthy crops. Overuse of chemical fertilizers especially
nitrogen-based ones can make plants overly succulent, which attracts sucking pests such
as the brown plant hopper in rice.
To maintain soil fertility and improve crop resilience, adopt production practices such
as:
• Applying crop residues or other biomass as surface mulch.
• Using compost and green manures.
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
• Intercropping legumes within cropping systems.
• Employing biological control methods to manage insect pests and diseases.
These practices not only enhance yields but also sustain long-term soil health.
❖ Understanding the Crop Ecosystem
The pest complex (types of pests present) and the natural enemy complex (beneficial
predators and Parasitoides) are determined by the specific crop ecosystem.
• The pest complex of cotton is entirely different from that of sorghum.
• In rice, pests in a wet ecosystem differ from those in a dry ecosystem.
Key Considerations for Pest Management
Any pest management decision should be based on the characteristics of the crop
ecosystem, which include:
• Cropping pattern
• Pest–predator population balance
• Stage of crop growth
Note: Management practices effective for one crop may not be suitable for another.
Examples
• Helicoverpa in pigeon pea (Andhra Pradesh & Gulbarga): Farmers shake
the plants so that the insects fall onto a sheet, where they are collected and
destroyed.
• Leaf folder in paddy: A rope is pulled over the standing crop to dislodge and
control the pest.
❖ Examples of Practices for Natural Pest and Disease Management
o Disease management in natural farming
A plant is considered diseased when it cannot function normally, with the primary
causes being pathogens and environmental factors. Pathogens include viruses,
bacteria, fungi, nematodes, mycoplasma-like organisms, and parasitic higher plants,
with fungal pathogens being the most prevalent, responsible for seed rots, root rots,
foliage diseases, wilts, cankers, diebacks, galls, trunk rots, and decay in aging trees.
Environmental factors such as extreme temperatures, moisture stress, high winds, and
ice can directly damage plants and make them more susceptible to pest attacks.
Biodiversity plays an important role in sustainable agriculture, and crop
diversification—particularly mixing crop varieties—can significantly reduce disease
epidemics, though the best ways to structure such mixtures are still being studied.
Disease management strategies can be broadly grouped into two principles: prevention
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
(prophylaxis), which involves measures to avoid disease occurrence, and therapy,
which focuses on treating or controlling existing diseases.
I. Prophylactic Methods
A. Field Sanitation – Regularly remove weeds and infected crop residues to reduce
pest breeding grounds.
B. Seed Treatment – Coat seeds with natural substances (e.g., cow urine or ash) to
protect them from soil-borne pests.
II. Cultural Methods
A. Crop Rotation – Rotate crops to disrupt pest life cycles. Example: Rotating cereals
with legumes breaks pest cycles and improves soil health.
B. Intercropping – Grow pest-repellent plants alongside crops. Example: Marigold or
garlic with vegetables to deter pests.
C. Trap Crops – Plant trap crops (e.g., marigold, castor) near main crops to attract
pests away and monitor populations.
III. Adjusting Planting Schedules
• Time sowing and harvesting to avoid peak pest seasons.
• Example: Planting early-season crops can help avoid pest infestations during
peak breeding periods.
IV. Biological Methods
A. Habitat for Beneficial Insects – Create environments for natural predators such as
ladybugs, spiders, and predatory wasps. Example: Plant flowering hedgerows around
fields.
B. Botanical Extracts – Spray natural plant-based solutions to manage pest
populations.
Common Botanical Extracts:
1. Neemastra – Neem leaves + cow dung + cow urine; effective against sucking
pests and caterpillars.
2. Neem Seed Kernel Extract – Contact insecticide that disrupts pest growth
cycles.
3. Brahmastra – Neem, custard apple, papaya, and guava leaves fermented with
cow urine; bio-pesticide.
4. Agniastra – Chili-garlic extract; natural pest repellent.
5. Dashparni – Fermented mixture of 10 pest-repellent plant leaves for spray
applications.

EXERCISE NO. 11
WEED MANAGEMENT PRACTICES IN NATURAL FARMING
Weed management in natural farming focuses on ecological balance, soil health,
and minimal external inputs, aiming to suppress weeds without synthetic herbicides. It
emphasizes working with natural processes to manage weeds while maintaining crop
productivity. Below is a comprehensive overview of weed management practices in
natural farming, based on principles like those advocated by pioneers such as Masanobu
Fukuoka and practices observed in natural farming systems globally.
Key Principles of Weed Management in Natural Farming
1. Minimal Soil Disturbance: Avoiding tillage preserves soil structure, reduces
weed seed germination, and maintains beneficial microbial activity.
2. Crop Diversity and Rotation: Diverse cropping systems and rotations disrupt
weed life cycles and reduce dominance of specific weed species.
3. Soil Cover: Continuous soil cover with crops, cover crops, or mulch suppresses
weed growth by blocking sunlight and improving soil health.
4. Enhancing Natural Competition: Healthy crops and beneficial microorganisms
outcompete weeds for resources like light, water, and nutrients.
5. No Synthetic Inputs: Avoiding chemical herbicides and relying on natural
methods to control weeds.
Weed Management in Natural Farming: - Name of Practices
1. Mulching.
2. Mixed cropping.
3. Crop diversification.
4. Cover crop.
5. Water management.
6. Use of Weed Free Seeds
1. Mulching
Brief Description:
• Mulching or covering the soil surface can prevent weed seed germination by
blocking light transmission preventing seed germination.
• Mulches physically suppress weed seeds emergence.
• There are many forms of mulches available. The following two are suitable
practices of mulching in natural farming:
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
o Living mulch/Organic mulch:
▪ Usually a plant species that grows densely and low to the ground
such as clover.
▪ Can be planted before or after a crop is established.
▪ Important to kill and till in, or manage living mulch so it does not
compete with the actual crop.
▪ Primary purpose is to improve soil structure, aid fertility, or reduce
pest problems; weed suppression may be an added benefit.
o Soil mulch:
▪ Involves creating a protective layer of soil around plants or over
the soil surface to mimic natural processes.
▪ Particularly suited to regions with limited access to organic mulch
materials or where soil conservation is essential.
o Plant residue mulching:
▪ Uses leftover crop parts (e.g., straw, stalks, leaves, husks) as a
protective layer.
▪ Sustainable and cost-effective.
▪ Enhances soil fertility and reduces reliance on external inputs.
Benefits (Impact):
• Creates a physical barrier by covering the soil surface.
• Blocks sunlight from reaching weed seeds → inhibits germination and growth.
• Thick mulch layer suffocates small/emerging weeds.
• Fills soil gaps, leaving less space for weeds to establish.
• Prevents weed seed dispersion via wind/water.
• Maintains consistent moisture, discouraging weeds that thrive in dry conditions.
• Stabilizes soil temperature to prevent germination of weeds adapted to
fluctuations.
Protocol:
• Remove large weeds manually or with shallow tillage.
• Use crop residues like straw, husks, or leaves as by-products to minimize costs.
• Material should decompose naturally, enriching the soil with organic matter.
• Examples: Legumes (cowpea, mung bean), cereal residues (wheat, rice straw).
• Use residues that effectively block sunlight (e.g., maize stalks, sugarcane leaves).
• Ensure residues are pest- and disease-free.
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
• Avoid residues with toxic compounds (e.g., walnut, eucalyptus leaves).
• Select biomass-rich crops for thick, uniform mulch (e.g., sunflower stalks,
sorghum, pigeon pea).
• Choose residues suited to local soil and climate (e.g., grass clippings in tropics,
straw in temperate zones).
• Residues from nutrient-rich crops (e.g., groundnut, chickpea) can enhance
fertility.
• Consider crops with added benefits (e.g., erosion control, moisture conservation,
beneficial microbes).
• Apply 5–10 cm thick mulch; adjust based on material type.
• Leave 3–5 cm gap around stems to prevent rotting/pests.
• Spread mulch evenly to avoid patchy coverage.
2. Mixed Cropping
Brief Description:
• Age-old practice of cultivating two or more crops simultaneously on the same
land.
• Aligns with natural farming principles: ecological balance, biodiversity
conservation, low-input farming.
• Uses natural symbiotic relationships between crops to maintain productivity
without synthetic inputs.
Benefits (Impact):
• Combines crops with different growth patterns (e.g., tall + spreading) to shade
soil and limit sunlight for weeds.
• Example: Maize (vertical) + cowpea (spreading).
• Efficient nutrient use leaves fewer resources for weeds.
• Varied rooting depths exploit water differently, depriving weeds of moisture.
• Combined root systems occupy soil niches, preventing weed establishment.
• Some crops release allelochemicals (e.g., mustard, sorghum) that inhibit weed
germination/growth.
• Crop residues after harvest act as natural mulch.
• Crop diversity disrupts weed species lifecycles and alters microclimate to affect
weed seed germination/viability.
Protocol:
• Ensure crops have complementary growth habits and resource needs.
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
• Use suitable row ratios (e.g., 2:1, 4:1) for maximum coverage.
• Synchronize sowing to establish canopy early for weed suppression.
• Monitor fields in early stages to address weeds promptly.
• Grow crops with varied root depths, canopy structures, and growth habits.
• Grow different family crops to break weed cycles and change microclimate.
3. Crop Diversification
Brief Description:
• Sustainable natural farming approach to foster ecosystem health, optimize
resource use, and improve resilience.
• Enhances productivity while reducing environmental footprint.
Benefits (Impact):
• Different crops use different sunlight, water, and nutrients, limiting resources for
weeds.
• Tall crops (e.g., maize) shade soil; ground-hugging crops (e.g., legumes) cover
soil.
• Dense canopy prevents sunlight from reaching weed seeds.
• Allelopathic crops (e.g., mustard, sorghum, sunflower) inhibit weed germination.
• Crop rotation breaks weed lifecycles and prevents resistance.
• Varying root depths occupy different soil layers, reducing weed establishment.
• Example: Legumes (shallow roots) + maize/sunflower (deep roots).
• Reduced soil disturbance in diversified systems prevents weed seeds from being
exposed to favorable germination conditions.
• Example: Cover crops in rotation suppress weeds by maintaining continuous
cover.
Protocol:
• Understand local soil, climate, water, and pest pressure.
• Select crops with complementary growth patterns.
• Ensure crops differ in nutrient, water, and sunlight needs.
• Include allelopathic crops in the system.
• Design rotations alternating legumes and cereals.
• Use appropriate crop density for optimal canopy formation.
• Choose crops with staggered maturity periods for continuous coverage.
4. Cover Crops
Brief Description:
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
• Plants grown primarily to cover soil, not for harvest.
• Used in natural farming to enhance soil health, manage weeds, and support
sustainability.
• Typically planted in off-season or between main crop cycles.
Benefits (Impact):
• Rapid growth forms dense canopies that shade soil, blocking sunlight to weed
seeds.
• Compete with weeds for water, nutrients, and space.
• Some release allelopathic compounds (e.g., mustard, sunflower) to suppress
weeds.
• Roots disturb soil, making weed establishment harder.
• When mowed/decomposed, act as mulch and add organic matter.
• Rotation of cover crops disrupts weeds adapted to specific systems.
Protocol:
• Choose cover crops suited to climate, soil, and weed control needs.
• Legumes (e.g., clover, vetch) → add nitrogen + canopy suppression.
• Grasses (e.g., rye, oats) → quick coverage + root competition.
• Brassicas (e.g., mustard, radish) → allelopathic suppression.
• Broadleaf (e.g., buckwheat) → fast growth + smothering foliage.
• Plant at right time for maximum suppression.
• Ensure dense planting.
• Rotate cover crop species regularly.
5. Water Management
Brief Description:
• Effective water use in natural farming helps control weeds by influencing
germination, establishment, and competition.
Benefits (Impact):
• Timed irrigation (e.g., after crop emergence) reduces weed germination.
• Drip irrigation minimizes water for weeds between rows.
• Maintains soil moisture optimal for crops, limiting shallow-rooted weeds.
• Dry periods can prevent many weeds from germinating.

TECHNIQUES OF INDIGENOUS SEED PRODUCTION –
STORAGE AND MARKETING
Indigenous seed production in natural farming focuses on preserving local, heirloom, or
native seed varieties that are adapted to specific environments, climates, and soils. These
seeds are often resilient to pests, droughts, and other stresses without relying on synthetic
inputs. Natural farming pioneers like Masanobu Fukuoka and organizations such as
Navdanya emphasize community-led systems that maintain biodiversity, crop Vigor, and
socio-cultural networks. The process integrates seed selection, production, storage, and
marketing to create self-reliant farming systems. Below is an overview based on
traditional and sustainable practices.
Key Principles
1. Biodiversity and Adaptation: Prioritize seeds with high intra-population
variation, selected for resilience to local conditions like drought, floods, and pests.
2. Community Involvement: Farmers, often women and elders, lead selection,
exchange, and banking to foster reciprocity and knowledge sharing.
3. Minimal Inputs: Avoid chemicals; rely on natural methods like sun-drying,
companion planting, and organic treatments.
4. Sustainability: Techniques aim to reduce genetic erosion, enhance soil health,
and support long-term food sovereignty.
5. Integration with Ecosystems: Mimic natural processes, such as using cover
crops or polycultures to aid seed production.
Techniques for Indigenous Seed Production
Production involves selecting, growing, and harvesting seeds from native varieties in
ways that maintain genetic diversity and crop health.
1. Seed Selection:
o Choose plants that are healthier, taller (20-25% bigger), plumper, and
resistant to local stresses. For cereals like maize or wheat, select from
robust patches with larger cobs or panicles; thresh by hand and sun-dry.
For pulses (e.g., horsegram, pigeonpea), pick from vigorous plants and
winnow to remove low-quality seeds.
o Methods include mass selection (bulk harvest from superior plants), pure
line selection (isolating uniform traits), or class-bulking (grouping similar
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
varieties). Farmers use criteria like high yield without inputs, early
maturity, and pest resistance across five crop stages (seedling to maturity).
o In participatory plant breeding (PPB), collaborate with communities to
adapt varieties for organic systems.
2. Field Preparation and Planting:
o Use well-drained soils (sandy loams or silt loams) isolated from hybrid
varieties to prevent cross-pollination. Control weeds through minimal
tillage or summer fallow.
o Row spacing: 30-48 inches for species like Arizona cottontop or plains
bristlegrass to facilitate cultivation and higher yields. Plant at 25-50 pure
live seeds per linear foot, shallowly (0.25-1 inch deep).
o Timing: Late summer or spring for irrigated fields; ensure moisture for
germination. Incorporate intercropping or polycultures to enhance
biodiversity.
3. Harvesting:
o Harvest at hard-dough stage for optimal germination; use thumbnail test
(seed indents under pressure). Methods: Direct combining for short plants,
swathing for shatter-prone species, or mechanical brush/vacuum for large
quantities.
o For rice, harvest whole panicles; use ratooning or cloning for asexual
propagation. Sun-dry post-harvest to 13-14% moisture.
4. Fertilization and Weed Control:
o Avoid nitrogen during establishment; use phosphorus if soil tests indicate
need. For established fields, apply natural fertilizers like compost.
o Mechanical inter-row cultivation (1-2 inches deep) or hand-roguing for
weeds; promote natural competition.
Techniques for Seed Storage
Storage preserves viability, preventing mold, pests, and genetic degradation. Aim for
cool, dry conditions (temperature + humidity < 100).
1. Drying:
o Naturally sun-dry seeds to 10-15% moisture; use warm air (<108°F) for
bulk. Smoke treatment for some vegetables.
2. Containers and Methods:
o Traditional: Clay pots, earthenware, calabashes, or handcrafted vessels
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
sealed with mud, neem leaves, ash, sand, or matchsticks for pest control.
Store on shelves to avoid moisture.
o Vacuum sealing for tropical climates; wooden boxes or soil pits for tubers
like potatoes.
o Community Seed Banks: Store orthodox seeds (e.g., rice, maize) at room
temperature or controlled (0-10°C active, -20°C base). Digital
documentation via apps for traits and knowledge.
3. Duration and Monitoring:
o Viability lasts 3-6 years under ideal conditions; check regularly for
infections. Regenerate in similar environments if needed.
Techniques for Marketing
Marketing focuses on value addition, community networks, and niche markets for
organic, heritage seeds.
1. Community Exchanges and Loans:
o Exchange within villages or networks; return with 20-25% interest to
account for losses. Seed loans via cooperatives foster reciprocity.
2. Cooperatives and Sales:
o Form Farmer Producer Organizations (FPOs) for local/online sales,
organic markets, or festivals. Package as "climate-smart" or "heritage"
with certifications. Value addition: Process into grains or products for
revenue.
3. Seed Tourism and Digital Platforms:
o Promote villages via trails, festivals, and workshops; generate income for
conservation. Use online databases (e.g., Genesys) for global access.
4. Contracts and Niche Markets:
o Secure contracts with agencies for restoration; certify for purity to
enhance marketability.
Advantages
• Resilience: Indigenous seeds reduce input costs and improve yields in changing
climates.
• Biodiversity: Preserves genetic diversity, supporting food sovereignty.
• Economic: Low-cost methods; marketing creates income through cooperatives.
• Cultural: Strengthens community networks and traditional knowledge.
Challenges
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
• Genetic Erosion: Modern varieties threaten indigenous ones; requires active
conservation.
• Storage Risks: High humidity/pests in tropics; initial setup for banks.
• Market Access: Limited demand; competition from hybrids.
• Labor: Selection and exchange can be time-intensive.
Pragmatic guidance
• Start with local varieties; document traits digitally for sharing.
• Test small plots for selection; involve women in vegetable exchanges.
• Use neem/ash mixtures for pest-free storage; regenerate seeds every 2-3 years.
• Build cooperatives for marketing; attend seed festivals to network.
• Adapt to climate: Select drought-resistant traits in red zones.

PARTIAL AND COMPLETE NUTRIENT AND FINANCIAL
BUDGETING IN NATURAL FARMING
Partial and Complete Nutrient and Financial Budgeting in Natural Farming
Natural farming prioritizes sustainable, low-input systems that enhance soil
health, biodiversity, and self-sufficiency without synthetic chemicals. Nutrient budgeting
in this context assesses the balance of essential elements like nitrogen (N), phosphorus
(P), and potassium (K) through natural cycles, while financial budgeting focuses on
minimizing costs and maximizing returns via local resources. These tools help farmers
evaluate efficiency, identify imbalances, and make informed decisions. Below is an
expanded overview drawing from organic and zero-budget natural farming (ZBNF)
practices, incorporating additional data from case studies and research. In ZBNF, nutrient
sources include microbial inoculants, mulching, and crop residues, aiming for a closed-
loop system where 98-98.5% of plant nutrition comes from air, water, and sunlight, and
only 1.5% from soil. Budgets can be partial (simplified) or complete (comprehensive),
applied at field, rotation, or farm levels.
Nutrient Budgeting in Natural Farming
Nutrient budgeting quantifies inputs (e.g., atmospheric deposition, biological
fixation, manures) and outputs (e.g., crop removal, losses via leaching) to maintain soil
fertility. In natural farming, it aligns with principles like using Jeevamrutha (microbial
cultures) and mulching to recycle nutrients. Additional research highlights the role of
nutrient budgets in quantifying sustainability across scales, from plots to national levels,
with challenges in measuring terms like gaseous losses or internal transfers. For instance,
in East African mixed farming systems, field-scale budgets revealed N surpluses of 10-
30 kg/ha in high-input fields but deficits in low-input ones, emphasizing the need for
legume integration.
Key Principles
• Focus on Sustainability: Emphasizes biological fixation (e.g., legumes fixing
100-200 kg N/ha in clover leys), minimal external inputs, and reducing losses
through cover crops and no-till. In organic farms, farm-gate budgets assess N, P,
K, S, and Mg, showing surpluses (e.g., +20 kg N/ha) in livestock-integrated
systems but deficits in stockless ones.
• Nutrients Considered: Primarily N, P, K; secondary macronutrients (Ca, Mg, S)
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
and micronutrients (e.g., Zn, Cu) in detailed assessments.
• Data Sources: Farm records, soil tests, published tables (e.g., nutrient content in
manures, crops), and lab analyses.
Partial Nutrient Budgeting
This simplified approach compares major inputs and outputs without accounting for all
losses (e.g., erosion, runoff) or additions (e.g., sediment deposition), making it practical
for quick assessments. It's useful in natural farming for monitoring harvested nutrients
vs. applied organic matter. In maize-based systems under low-external-input farming,
partial budgets showed N balances of -5 to +15 kg/ha, with improved efficiency from
intercropping.
• Methods and Calculations:
o Steps:
1. Measure crop yield (e.g., dry matter in tons/ha).
2. Determine nutrient removal using concentrations (e.g., % N in
crop) and formulas like: Nutrient removal (kg/ha) =
(Concentration % / 100) × Dry matter yield (kg/ha).
3. Sum inputs (e.g., manures, fixation) and subtract removals: Budget
(kg/ha) = Inputs - Removals.
o Applications: For single crops or fields; positive budgets build soil
reserves, negative deplete them. In India, partial budgets for primary
nutrients indicate national deficits (e.g., -10 to -20 kg K/ha), highlighting
overuse of N but underuse of K in natural systems.
• Example: In a ZBNF paddy field, partial budget for N might show inputs from
Jeevamrutha (providing ~39% of needs) minus crop removal, revealing a deficit
if not supplemented by fixation. For alfalfa, removal is ~12 kg P₂O₅/ton dry
matter. A potato case study details partial N budgets, estimating removals of 150-
200 kg N/ha based on yield, aiding fertilizer adjustments in organic setups.
Complete Nutrient Budgeting
This holistic method includes all inputs, outputs, internal flows (e.g., crop residues,
manure cycling), and losses, providing a full picture for long-term soil health in natural
farming. In forage and grain crops, complete budgets measure removals via sampling,
with N losses up to 50 kg/ha from leaching in high-rainfall areas.
• Methods and Calculations:
o Steps:
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
1. Record all inputs: Fixation (e.g., 100-200 kg N/ha from clover),
deposition, manures (e.g., 50 kg N/ton cattle slurry).
2. Track outputs: Crop off-take (e.g., 150 kg N/ha in wheat),
livestock products, losses (leaching ~30 kg N/ha surplus target).
3. Include internal cycles: Residues returned to soil.
4. Calculate surplus/deficit: Surplus (kg/ha) = Total inputs - (Outputs
+ Losses).
o Systems Framework: Covers Soil-Plant, Animal, and integrated systems.
In wastewater-agroforestry integration, complete budgets in Jamaica
showed nutrient recovery rates of 70-80% for N and P.
• Example: On a mixed organic farm (60 ha), complete budget shows N surplus
+51 kg/ha, P +1 kg/ha, K -19 kg/ha, guiding adjustments like more legumes for
K balance. In German organic farms, farm-gate budgets revealed S deficits (-5
kg/ha) in vegetable systems, recommending sulfur-rich amendments.
Comparison of Partial vs. Complete Nutrient Budgeting

Added Data
Example
Maize: -5 to +15 kg N/ha in low-
input systems
Organic farms: S deficit -5
kg/ha in vegetables
Financial Budgeting in Natural Farming
Financial budgeting plans income, expenses, and cash flows, emphasizing cost reduction
in natural farming through local inputs like cow dung and mulching. In ZBNF, it's "zero-
budget" as net costs approach zero via self-produced inputs. Case studies from Andhra
Pradesh show ZBNF reducing input costs by 9-36%, with yields 1-23% higher,
potentially saving Rs. 12,396 crore statewide if scaled. In Karnataka, ZBNF adoption via
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
peasant movements has scaled to millions, with economic benefits from reduced debt.
Key Principles
• Low-Cost Focus: Eliminate chemical inputs; use on-farm resources (e.g.,
Jeevamrutha costs ~3-75% less). Partial ZBNF adopters spend INR 4,664/acre on
mixed inputs.
• Types: Enterprise (crop-specific), whole-farm (overall), cash flow (timing
inflows/outflows).
• Government Support: Schemes like PKVY (Rs. 12,200/ha over 3 years) aid
transitions.
Partial Financial Budgeting
Assesses marginal changes (e.g., adopting mulching), comparing added
revenues/reduced costs vs. reduced revenues/added costs. In soil health case studies,
partial budgets showed ROI of 15-30% from practices like cover cropping.
• Methods and Calculations:
o Steps: List gains (e.g., higher yields) and losses (e.g., new tool costs);
calculate net change: Net = Total gains - Total losses.
o Applications: Evaluate shifts like herbicide-resistant seeds in natural
contexts.
• Example: Switching to ZBNF for rice: Gains (22.6% lower costs, Rs. 42,765/ha
vs. Rs. 55,286/ha conventional) minus losses (potential yield drop); net +Rs.
12,521/ha if yields stable. In AP, partial budgets for ZBNF showed cost savings
of INR 3,000-5,000/acre in initial years.
Complete Financial Budgeting
Whole-farm or cash flow budgets cover all operations, forecasting revenues (e.g., crop
sales) and expenses (e.g., labor). In climate-resilient ZBNF, complete budgets in
Anantapuramu district revealed 20-40% higher net incomes due to diversified cropping.
• Methods and Calculations:
o Steps: Project inflows (sales, subsidies) and outflows (inputs, labor);
monitor monthly cash flow.
o Applications: For diversified farms; in ZBNF, aims for zero net (e.g.,
savings Rs. 300-360 crores statewide).
• Example: Andhra Pradesh ZBNF farm: Costs 9-36% lower, yields 1-23% higher,
net revenues up, with state savings Rs. 12,396 crore if scaled. A multi-state study
showed ZBNF farms achieving net profits 15-25% higher than conventional due
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
to lower subsidies needs.
Advantages
• Nutrient: Improves soil health, reduces pollution; ZBNF cuts N deficit risks with
supplements. Soil health practices yield long-term benefits like reduced erosion
costs.
• Financial: Lowers debt (e.g., diversified systems economically preferable).
Enhances resilience; ZBNF could save fertilizer subsidies in India.
Challenges
• Nutrient: Initial deficits in ZBNF (e.g., 37-54% yield drops without manure).
Data accuracy issues; scaling challenges in variable climates.
• Financial: Yield variability affects returns; scaling risks food security.
Constraints include knowledge gaps and market access.

EVALUATION OF ECOSYSTEM SERVICES IN NATURAL
FARMING (CROP, FIELD AND SYSTEM)
Ecosystem services (ES) refer to the benefits humans derive from ecosystems,
categorized into provisioning (e.g., food, water), regulating (e.g., pest control, climate
regulation), supporting (e.g., nutrient cycling, soil formation), and cultural (e.g.,
recreation, education). Natural farming, encompassing practices like organic,
regenerative, and agroecological systems with minimal inputs, no-till, and biodiversity
enhancement, promotes these services by mimicking natural processes. Evaluation
involves assessing indicators through field measurements, economic valuation (e.g.,
willingness to pay, contingent valuation), and modeling to quantify benefits, synergies,
and trade-offs. This overview draws from studies on organic and regenerative systems,
often analogous to natural farming, evaluating ES at crop (individual plant/crop focus),
field (plot-scale interactions), and system (farm/landscape integration) levels.
Evaluation at Crop Level
At the crop level, ES focus on direct benefits to plant growth, yield, and quality,
emphasizing provisioning (biomass, food) and regulating services (pollination, pest
control). Natural farming enhances these through diverse varieties, intercropping, and
biological inputs, reducing chemical dependency.
• Key Services and Benefits:
o Provisioning: Higher biomass for food/feed, e.g., in organic systems, crop
yields can match conventional with added resilience.
o Regulating: Pollination (e.g., by insects) and biological pest control via
beneficial predators; intercropping reduces pest infestations.
o Supporting: Nutrient uptake and soil fertility enhancement from microbial
activity.
o Cultural: Aesthetic value from diverse crops.
• Evaluation Methods and Indicators:
o Methods: Yield measurements, pollinator surveys, and pest predation
rates; economic valuation via minimum support prices for food/by-
products.
o Indicators: Crop yield (tons/ha), pollinator abundance (e.g., bee
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
visits/plant), pest control efficiency (predation rates), nutrient uptake
(kg/ha). For rice in eastern India, provisioning ES (food/by-products)
valued at US$1052–1234/ha/year, with biological pest control at US$1.6–
2.9/ha/year. In agroecological systems, win-win outcomes include
enhanced wheat yield with erosion control in conservation agriculture.
• Data and Examples: In regenerative cereal crops, crop-level ES benefits include
$196,504 (Fund I) for biological control, with net benefits of $3,762/acre over
conventional. Organic cotton in agroecological systems shows yield
enhancements with soil carbon increases. Trade-offs: Lower cereal yields in
organic transitions but higher biodiversity.
Evaluation at Field Level
Field-level evaluation examines plot-scale interactions, including soil health, water
management, and biodiversity, with strong emphasis on regulating (erosion control,
nutrient cycling) and supporting services (soil structure).
• Key Services and Benefits:
o Provisioning: Soil fertility for sustained yields; cover crops provide
additional biomass.
o Regulating: Erosion reduction, water retention, and pest/weed control via
cover/intercropping.
o Supporting: Soil organic matter buildup, microbial diversity.
o Cultural: Scenic beauty from heterogeneous fields.
• Evaluation Methods and Indicators:
o Methods: Soil sampling (e.g., organic carbon, erosion rates via RUSLE),
biodiversity surveys, and water infiltration tests; monetization (e.g.,
Int.$3453/ha/year for regulating in grasslands).
o Indicators: Soil carbon levels (%), water infiltration (mm/hour), species
richness (arthropods/plants), erosion loss (tons/ha). In rice fields, soil
formation valued at US$2.8 × 10⁻⁸/ha/year, hydrological flow at
US$11.4/ha/year. Field robots/drones for real-time data on microclimates.
• Data and Examples: Organic farmlands in Taiwan show higher field-level ES
values for water purification and soil conservation than conventional.
Regenerative fields generate $10.2 million (Fund I) in habitat services, with air
quality benefits of $4.9 million net over conventional. In SRI, field practices like
intermittent flooding enhance water regulation and soil fertility. Challenges:
Mr. M. A. Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404
Initial yield drops (37-54%) in transitions without manure.
Evaluation at System Level
System-level assessment integrates farm/landscape scales, focusing on resilience,
connectivity, and broader impacts like climate regulation and biodiversity.
• Key Services and Benefits:
o Provisioning: Overall food security via diversified systems.
o Regulating: Carbon sequestration, flood mitigation, air purification.
o Supporting: Habitat connectivity, genetic diversity.
o Cultural: Education, recreation, spiritual value.
• Evaluation Methods and Indicators:
o Methods: Landscape modeling (e.g., habitat connectivity), GHG
accounting (COMET-Farm), and stakeholder surveys (willingness to pay
via CVM); PCA/cluster analysis for variability.
o Indicators: Biodiversity indices, carbon storage (tons/ha), resilience
metrics (recovery post-disturbance), landscape heterogeneity (hedgerow
density). System ES in organic farms: Int.$8096/ha/year for regulating,
Int.$3016/ha/year for habitat.
• Data and Examples: Total ES in eastern India rice systems: US$1238–
1688/ha/year, with supporting services like nutrient cycling at US$64–
487/ha/year. Regenerative systems net $21.4 million (Fund I) in ES benefits,
including $34.4 million for habitat. Organic systems in Taiwan have highest
overall ES value among farmland types. In AEI, >50% win-win outcomes in
conservation and precision agriculture for multifunctionality.

CASE STUDIES AND SUCCESS STORIES IN NATURAL
FARMING AND CHEMICAL-FREE TRADITIONAL FARMING
Natural farming and chemical-free traditional farming in India emphasize
sustainable practices like Zero Budget Natural Farming (ZBNF), organic methods,
vermicomposting, and agroecology, rooted in traditional knowledge and modern ecology.
These approaches reduce input costs, enhance soil health, boost biodiversity, and improve
farmer incomes while addressing environmental challenges like soil degradation and
water scarcity. Below is a compilation of key case studies and success stories, drawn from
government initiatives, research, and farmer experiences across states. They highlight
transitions from chemical-intensive to natural/organic systems, with quantifiable
outcomes where available.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 EXERCISE NO. 5 STUDIES IN GREEN MANURING IN-SITU AND GREEN LEAF MANURING Introduction to Green Manuring Green manuring is a sustainable agricultural practice that involves incorporating undecomposed green plant tissue into the soil to improve its physical, chemical, and biological properties. This practice enhances soil fertility, reduces reliance on synthetic fertilizers, and promotes environmental sustainability. There are two primary types of green manuring: in-situ green manuring and green leaf manuring. In-Situ Green Manuring Definition In-situ green manuring refers to growing green manure crops directly in the field where the main crop will be planted. These crops are then incorporated into the soil, typically by ploughing or tilling, before the main crop is sown. Benefits of In-Situ Green Manuring • Improved Soil Structure: The roots of green manure crops help to break up compacted soil, improving aeration and water infiltration. The organic matter added to the soil enhances its structure, making it more friable and easier to work. • Enhanced Soil Fertility: Green manure crops fix atmospheric nitrogen through symbiotic relationships with bacteria in their root nodules. When incorporated into the soil, this nitrogen becomes available to subsequent crops. They also help in solubilizing unavailable forms of phosphorus and potassium. • Weed Suppression: A dense stand of green manure crops can suppress weed growth by competing for resources such as sunlight, water, and nutrients. • Reduced Soil Erosion: The cover provided by green manure crops protects the soil from wind and water erosion, conserving topsoil and preventing nutrient loss. • Increased Soil Organic Matter: The incorporation of green manure adds organic matter to the soil, which improves its water-holding capacity, nutrient retention, and overall soil health. • Beneficial Microbe Activity: Green manuring promotes the growth and activity of beneficial soil microorganisms, such as bacteria and fungi, which play a crucial role in nutrient cycling and disease suppression.
  • 33.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 Methods of In-Situ Green Manuring 1. Growing Green Manure Crops Before the Main Crop: This involves planting a green manure crop after harvesting the previous main crop and allowing it to grow for a specific period before incorporating it into the soil. 2. Intercropping Green Manure Crops with the Main Crop: Green manure crops can be intercropped with the main crop, either in rows or as a cover crop between rows. The green manure crop is then incorporated into the soil after the main crop is harvested or at a suitable stage of growth. 3. Relay Cropping Green Manure Crops: This involves planting the green manure crop before harvesting the main crop, allowing it to establish before the main crop is removed. The green manure crop then continues to grow and is later incorporated into the soil. Suitable Crops for In-Situ Green Manuring • Legumes: Legumes such as cowpea (Vigna unguiculata), sunn hemp (Crotalaria juncea), dhaincha (Sesbania aculeata), and cluster bean (Cyamopsis tetragonoloba) are excellent green manure crops due to their ability to fix atmospheric nitrogen. • Non-Legumes: Non-legumes such as mustard (Brassica juncea), buckwheat (Fagopyrum esculentum), and rye (Secale cereale) can also be used as green manure crops. They are effective at scavenging nutrients from the soil and improving soil structure. Considerations for In-Situ Green Manuring • Timing: The timing of planting and incorporating the green manure crop is crucial. It should be planted early enough to allow sufficient growth before incorporation, but not so late that it interferes with the planting of the main crop. • Incorporation: The green manure crop should be incorporated into the soil when it is succulent and easily decomposable. This is typically at the flowering stage. • Moisture: Adequate soil moisture is essential for the decomposition of green manure. If the soil is dry, irrigation may be necessary. • Nutrient Management: The amount of nitrogen fixed by the green manure crop depends on factors such as the species of crop, soil conditions, and management practices. It is important to consider the nutrient requirements of the subsequent crop and adjust fertilizer applications accordingly. Green Leaf Manuring
  • 34.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 Definition Green leaf manuring involves collecting green leaves and twigs from trees, shrubs, and other plants growing in nearby areas and incorporating them into the soil of cultivated fields. Benefits of Green Leaf Manuring • Nutrient Enrichment: Green leaves are rich in essential plant nutrients such as nitrogen, phosphorus, and potassium. When incorporated into the soil, these nutrients are released slowly, providing a sustained supply to the crop. • Improved Soil Structure: The organic matter added through green leaf manuring improves soil structure, increasing its water-holding capacity and aeration. • Weed Suppression: A layer of green leaves on the soil surface can suppress weed growth by blocking sunlight and preventing weed seeds from germinating. • Reduced Soil Erosion: Green leaf manure acts as a mulch, protecting the soil from wind and water erosion. • Cost-Effective: Green leaf manuring can be a cost-effective alternative to synthetic fertilizers, especially in areas where green leaves are readily available. Methods of Green Leaf Manuring 1. Collection of Green Leaves: Green leaves and twigs are collected from trees, shrubs, and other plants growing in nearby areas. 2. Application to the Field: The collected green leaves are spread evenly over the field before plowing or tilling. 3. Incorporation into the Soil: The green leaves are incorporated into the soil by plowing or tilling. Suitable Sources of Green Leaves • Leguminous Trees: Leguminous trees such as Gliricidia sepium, Leucaena leucocephala, and Sesbania grandiflora are excellent sources of green leaves due to their high nitrogen content. • Non-Leguminous Trees: Non-leguminous trees such as neem (Azadirachta indica), pongamia (Pongamia pinnata), and subabul (Leucaena leucocephala) can also be used as sources of green leaves. • Shrubs and Weeds: Certain shrubs and weeds can also be used as sources of green leaves, provided they are not toxic or invasive. Considerations for Green Leaf Manuring • Availability: The availability of green leaves is a major consideration. It is
  • 35.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 important to ensure that there is a sustainable supply of green leaves without depleting natural resources. • Decomposition: The rate of decomposition of green leaves depends on factors such as the species of plant, the age of the leaves, and soil conditions. It is important to choose leaves that decompose readily. • Nutrient Content: The nutrient content of green leaves varies depending on the species of plant and growing conditions. It is important to analyze the nutrient content of the leaves to determine the appropriate application rate. • Labor Requirements: Green leaf manuring can be labor-intensive, especially for collection and application. It is important to consider the labor requirements when planning to use this practice.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 EXERCISE NO. 8 NUTRIENT MANAGEMENT IN NATURAL FARMING Natural Farming, at its core, emphasizes working in harmony with nature to create a self-sustaining agricultural ecosystem. Nutrient management in this context is not about directly supplying nutrients to plants through synthetic fertilizers. Instead, it focuses on creating a thriving soil ecosystem that naturally provides plants with the nutrients they need. Key principles include: • Soil as a Living Ecosystem: Recognizing the soil as a complex web of life, including bacteria, fungi, earthworms, and other organisms, is fundamental. These organisms play a crucial role in nutrient cycling and availability. • Minimizing Soil Disturbance: Tillage disrupts the soil structure and harms beneficial organisms. Natural Farming advocates for minimal or no-till practices to preserve soil health. • Cover Cropping and Mulching: These practices protect the soil surface, suppress weeds, retain moisture, and add organic matter, which feeds soil organisms. • On-Farm Input Generation: Natural Farming promotes the use of locally available resources to create nutrient-rich inputs, reducing reliance on external sources. • Diversity and Integration: Integrating diverse crops and livestock creates a more resilient and balanced ecosystem, enhancing nutrient cycling. Key Practices for Nutrient Management Several key practices are employed in Natural Farming to manage nutrients effectively: 1. Enhancing Soil Health • No-Till or Minimal Tillage: Avoiding or minimizing tillage preserves soil structure, reduces erosion, and protects beneficial soil organisms. • Cover Cropping: Planting cover crops between cash crops helps improve soil fertility, suppress weeds, and prevent erosion. Leguminous cover crops, such as clover or vetch, fix atmospheric nitrogen, enriching the soil. • Mulching: Applying organic mulches, such as straw, leaves, or wood chips, helps retain soil moisture, suppress weeds, regulate soil temperature, and add organic matter as they decompose. • Composting: Composting organic waste materials, such as crop residues, animal
  • 43.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 manure, and kitchen scraps, creates a nutrient-rich soil amendment. Compost improves soil structure, water-holding capacity, and nutrient availability. 2. On-Farm Input Preparation Natural Farming emphasizes the use of locally available resources to create nutrient-rich inputs. Some common preparations include: • Jivamrita: A fermented microbial culture made from cow dung, cow urine, jaggery, pulse flour, and soil. Jivamrita is applied to the soil to inoculate it with beneficial microorganisms, which enhance nutrient availability and soil health. • Beejamrita: A seed treatment made from cow dung, cow urine, lime, and soil. Beejamrita protects seeds from soilborne pathogens and promotes germination and seedling vigor. • Ghanajivamrita: A solid form of Jivamrita, made by drying and powdering the fermented mixture. Ghanajivamrita is applied to the soil as a slow-release fertilizer. • Neemastra: A biopesticide made from neem leaves, cow urine, and water. Neemastra repels pests and protects crops from damage. • Brahmastra: A biopesticide made from various plant extracts, such as neem, datura, and custard apple leaves. Brahmastra is used to control a wider range of pests. • Agniastra: A biopesticide made from tobacco, green chilies, garlic, ginger, and cow urine. Agniastra is used to control sucking pests. 3. Optimizing Nutrient Availability • Crop Rotation: Rotating crops with different nutrient requirements helps prevent nutrient depletion and improves soil health. Legumes, for example, fix nitrogen in the soil, benefiting subsequent crops. • Intercropping: Growing multiple crops together can enhance nutrient utilization and suppress weeds. Companion planting, where specific crops are grown together to benefit each other, is also a valuable strategy. • Panchagavya: A fermented mixture of cow dung, cow urine, milk, curd, and ghee. Panchagavya is used as a foliar spray to promote plant growth and enhance nutrient uptake. • Effective Microorganisms (EM): EM solutions contain a consortium of beneficial microorganisms that can improve soil health, enhance nutrient availability, and suppress plant diseases.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 Benefits of Nutrient Management in Natural Farming • Improved Soil Health: Natural Farming practices enhance soil structure, water- holding capacity, and nutrient availability, leading to healthier and more fertile soils. • Reduced Reliance on External Inputs: By utilizing on-farm resources and promoting natural nutrient cycling, Natural Farming minimizes the need for synthetic fertilizers and pesticides. • Enhanced Crop Quality: Crops grown using Natural Farming methods are often more nutritious and have better flavour and shelf life. • Increased Biodiversity: Natural Farming promotes biodiversity by creating a more diverse and balanced ecosystem. • Environmental Sustainability: Natural Farming practices reduce pollution, conserve water, and promote carbon sequestration, contributing to a more sustainable agricultural system. • Climate Resilience: Healthy soils are more resilient to climate change impacts, such as drought and flooding. Challenges and Considerations While Natural Farming offers numerous benefits, it also presents some challenges: • Transition Period: Converting to Natural Farming may require a transition period during which yields may initially decline. • Knowledge and Skill: Successful implementation of Natural Farming requires a good understanding of soil ecology, crop management, and on-farm input preparation. • Labor Intensive: Some Natural Farming practices, such as on-farm input preparation, can be labor-intensive. • Market Access: Access to markets that value and reward Natural Farming products may be limited in some areas. • Validation and Research: More research is needed to validate the effectiveness of Natural Farming practices and to optimize them for different agro-ecological zones. Nutrient management in Natural Farming is a holistic approach that focuses on building healthy soils and promoting natural nutrient cycling. By adopting practices such as no- till farming, cover cropping, mulching, on-farm input preparation, and crop diversification, farmers can create self-sustaining agricultural ecosystems that are both

Mob. 9403183404 EXERCISE NO. 9 & 10 INSECT- PEST, AND DISEASE MANAGEMENT IN NATURAL FARMING Natural farming emphasizes sustainable, eco-friendly methods to manage insects, pests, and diseases, focusing on maintaining ecological balance rather than eradicating pests entirely. Below is a concise overview of strategies used in natural farming for insect, pest, and disease management, based on principles like those in Zero Budget Natural Farming (ZBNF) and organic practices: Natural pest and disease management practices harness the ecological principles such as biodiversity, food web, resilience, natural pest suppression, etc. to control pest populations and disease incidence in a sustainable way, without relying on usage of inputs such as pesticides, insecticides etc. A natural farming farm invites a wide range of organisms, including beneficial insects, birds etc providing ecosystem services such as pollination, natural pest control, maintenance of natural food cycle (predator-prey relationships which reduces the likelihood of pest outbreaks). By fostering environmental balance, promoting biodiversity, and ensuring long-term soil health, it aligns with the principles of sustainable agriculture and Natural Farming. A. Insect- pest management in natural farming The ecological and economical problems of pests and pesticides in agriculture gave rise to several eco-friendly innovative approaches which do not rely on the use of chemical pesticides. These initiatives involved rediscovering traditional practices and contemporary grass root innovations supplemented by strong scientific analysis mainly supported by non-formal institutions like NGOs. Such innovations have begun to play an important role in development sector. This trend has important implications both for policy and practice. The “Non Pesticidal Management” which emanates from collaborative work of public institutions, civil society organizations and Farmers in Andhra Pradesh shows how diverse players join hands to work in generating new knowledge and practice, can evolve more sustainable models of development. Several voluntary agencies, farmers from different regions and few scientists from the subject area established that: ❖ Red Hairy Caterpillar ➢ This pest infests crops only on light red soils
  • 47.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 ➢ There is only one generation of moths that lay eggs producing the cater- pillars which later hibernate in the soils. Adult moths appear in waves at the onset of the monsoon. Controlling the pest necessitated the destruction of the early emergence moths. ➢ The caterpillars are also attracted to some wild non-economical plants such as Calotropis, wild castor, yellow cucumber. ➢ The later instars of larvae had dense red hairs all over the body, which prevents pesticides from reaching the body of the insects as a result any pesticide sprayed will not cause the mortality of the insect. Package of practices were evolved based on the insect behaviour, which can manage the RHC before it reaches damaging stages and proportions. Deep summer ploughing exposes the resting pupae, adults of RHC. These insects are attracted to light- community bonfires. Bonfires were used to attract the insects and kill them. Alternatively light traps (electric bulbs or solar light) were also used. Trenches around the field to trap migrating larvae by use of Calotropis and jatropha cuttings were found to be effective. Neem sprays on the early instar larvae were found to be effective. Pest is not a problem but a symptom. Disturbance in the ecological balance among different components of crop ecosystem makes certain insects reach pest status. From this perspective evolved the Non Pesticidal Management which is an “ecological approach to pest management using knowledge and skill-based practices to prevent insects from reaching damaging stages and damaging pro- portions by making best use of local resources, natural processes and community action. ❖ Non Pesticidal Management is mainly based on: ➢ Understanding crop ecosystem and suitably modifying it by adopting suitable cropping systems and crop production practices. The type of pests and their behaviour differs with crop ecosystems. Similarly, the natural enemies’ composition also varies with the cropping systems. ➢ Understanding insect biology and behaviour and adopting suitable preventive measures to reduce the pest numbers. ➢ Building farmers knowledge and skills in making the best use of local resources and natural processes and community action. Natural ecological balance which ensures that pests do not reach a critical number in the field that endangers the yield. Nature can restore such a balance if it is not too much meddled with. Hence

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 no chemical pesticides/pesticide are applied to the crops. For an effective communication to farmers about the concept effectively, and to differentiate from Integrated Pest Management which believes that chemical pesticides can be safely used and are essential as lost resort it is termed as “Non Pesticidal Management. ❖ Growing Healthy Plants from Good Quality Seed • Seed Selection: o Choose locally adapted seeds (traditional farmers’ varieties or improved varieties from public sector institutions). o Use a seed matrix to evaluate: ▪ Suitability for cropping patterns. ▪ Compatibility with soil types. ▪ Resistance to insect pests and diseases. ▪ Alignment with consumption preferences. o Maintain seeds in seed banks for timely sowing and farmer control. • Timely Sowing: o Critical in rainfed areas to ensure crop health and productivity. o Enables optimal use of monsoon rains and reduces pest/disease vulnerability. • Seed Treatment: o Cow urine, ash, and asafoetida concoction: Protects against seed-borne diseases (e.g., rice blast). o Beejamrutha: Promotes soil microbial activity and eliminates seed-borne pathogens. o Milk dipping for brinjal seedlings: Dip seedlings or fingers in milk before transplanting to prevent viral infections. • Non-Pesticidal Management (NPM): o Adopt practices to prevent insects from reaching damaging stages or populations: ▪ Crop rotation and intercropping: Disrupt pest life cycles. ▪ Trap crops: Attract pests away from main crops (e.g., Calotropis for Red Hairy Caterpillar). ▪ Biological control: Encourage natural predators (e.g., birds, Trichogramma wasps) or use Bacillus thuringiensis (Bt). ▪ Physical barriers: Use nets, row covers, or sticky traps.
  • 49.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 ▪ Natural repellents: Apply neem-based solutions (e.g., Agninastra), wood ash, or cow dung ash. ▪ Field sanitation: Remove crop residues and weeds to reduce pest habitats. ▪ Light/pheromone traps: Capture moths to prevent egg-laying (e.g., Red Hairy Caterpillar moths). ▪ Hand-picking: Remove early instar larvae to prevent population buildup. ❖ Reduce Stress The pest and disease susceptibility increases with abiotic stress. Practices like mulching will improve the soil moisture availability. Fig. 1 Schematic representation of non-pesticidal management. ❖ Build Healthy Soils Healthy soils lead to healthy crops. Overuse of chemical fertilizers especially nitrogen-based ones can make plants overly succulent, which attracts sucking pests such as the brown plant hopper in rice. To maintain soil fertility and improve crop resilience, adopt production practices such as: • Applying crop residues or other biomass as surface mulch. • Using compost and green manures.
  • 50.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 • Intercropping legumes within cropping systems. • Employing biological control methods to manage insect pests and diseases. These practices not only enhance yields but also sustain long-term soil health. ❖ Understanding the Crop Ecosystem The pest complex (types of pests present) and the natural enemy complex (beneficial predators and Parasitoides) are determined by the specific crop ecosystem. • The pest complex of cotton is entirely different from that of sorghum. • In rice, pests in a wet ecosystem differ from those in a dry ecosystem. Key Considerations for Pest Management Any pest management decision should be based on the characteristics of the crop ecosystem, which include: • Cropping pattern • Pest–predator population balance • Stage of crop growth Note: Management practices effective for one crop may not be suitable for another. Examples • Helicoverpa in pigeon pea (Andhra Pradesh & Gulbarga): Farmers shake the plants so that the insects fall onto a sheet, where they are collected and destroyed. • Leaf folder in paddy: A rope is pulled over the standing crop to dislodge and control the pest. ❖ Examples of Practices for Natural Pest and Disease Management o Disease management in natural farming A plant is considered diseased when it cannot function normally, with the primary causes being pathogens and environmental factors. Pathogens include viruses, bacteria, fungi, nematodes, mycoplasma-like organisms, and parasitic higher plants, with fungal pathogens being the most prevalent, responsible for seed rots, root rots, foliage diseases, wilts, cankers, diebacks, galls, trunk rots, and decay in aging trees. Environmental factors such as extreme temperatures, moisture stress, high winds, and ice can directly damage plants and make them more susceptible to pest attacks. Biodiversity plays an important role in sustainable agriculture, and crop diversification—particularly mixing crop varieties—can significantly reduce disease epidemics, though the best ways to structure such mixtures are still being studied. Disease management strategies can be broadly grouped into two principles: prevention
  • 51.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 (prophylaxis), which involves measures to avoid disease occurrence, and therapy, which focuses on treating or controlling existing diseases. I. Prophylactic Methods A. Field Sanitation – Regularly remove weeds and infected crop residues to reduce pest breeding grounds. B. Seed Treatment – Coat seeds with natural substances (e.g., cow urine or ash) to protect them from soil-borne pests. II. Cultural Methods A. Crop Rotation – Rotate crops to disrupt pest life cycles. Example: Rotating cereals with legumes breaks pest cycles and improves soil health. B. Intercropping – Grow pest-repellent plants alongside crops. Example: Marigold or garlic with vegetables to deter pests. C. Trap Crops – Plant trap crops (e.g., marigold, castor) near main crops to attract pests away and monitor populations. III. Adjusting Planting Schedules • Time sowing and harvesting to avoid peak pest seasons. • Example: Planting early-season crops can help avoid pest infestations during peak breeding periods. IV. Biological Methods A. Habitat for Beneficial Insects – Create environments for natural predators such as ladybugs, spiders, and predatory wasps. Example: Plant flowering hedgerows around fields. B. Botanical Extracts – Spray natural plant-based solutions to manage pest populations. Common Botanical Extracts: 1. Neemastra – Neem leaves + cow dung + cow urine; effective against sucking pests and caterpillars. 2. Neem Seed Kernel Extract – Contact insecticide that disrupts pest growth cycles. 3. Brahmastra – Neem, custard apple, papaya, and guava leaves fermented with cow urine; bio-pesticide. 4. Agniastra – Chili-garlic extract; natural pest repellent. 5. Dashparni – Fermented mixture of 10 pest-repellent plant leaves for spray applications.

Mob. 9403183404 EXERCISE NO. 11 WEED MANAGEMENT PRACTICES IN NATURAL FARMING Weed management in natural farming focuses on ecological balance, soil health, and minimal external inputs, aiming to suppress weeds without synthetic herbicides. It emphasizes working with natural processes to manage weeds while maintaining crop productivity. Below is a comprehensive overview of weed management practices in natural farming, based on principles like those advocated by pioneers such as Masanobu Fukuoka and practices observed in natural farming systems globally. Key Principles of Weed Management in Natural Farming 1. Minimal Soil Disturbance: Avoiding tillage preserves soil structure, reduces weed seed germination, and maintains beneficial microbial activity. 2. Crop Diversity and Rotation: Diverse cropping systems and rotations disrupt weed life cycles and reduce dominance of specific weed species. 3. Soil Cover: Continuous soil cover with crops, cover crops, or mulch suppresses weed growth by blocking sunlight and improving soil health. 4. Enhancing Natural Competition: Healthy crops and beneficial microorganisms outcompete weeds for resources like light, water, and nutrients. 5. No Synthetic Inputs: Avoiding chemical herbicides and relying on natural methods to control weeds. Weed Management in Natural Farming: - Name of Practices 1. Mulching. 2. Mixed cropping. 3. Crop diversification. 4. Cover crop. 5. Water management. 6. Use of Weed Free Seeds 1. Mulching Brief Description: • Mulching or covering the soil surface can prevent weed seed germination by blocking light transmission preventing seed germination. • Mulches physically suppress weed seeds emergence. • There are many forms of mulches available. The following two are suitable practices of mulching in natural farming:
  • 53.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 o Living mulch/Organic mulch: ▪ Usually a plant species that grows densely and low to the ground such as clover. ▪ Can be planted before or after a crop is established. ▪ Important to kill and till in, or manage living mulch so it does not compete with the actual crop. ▪ Primary purpose is to improve soil structure, aid fertility, or reduce pest problems; weed suppression may be an added benefit. o Soil mulch: ▪ Involves creating a protective layer of soil around plants or over the soil surface to mimic natural processes. ▪ Particularly suited to regions with limited access to organic mulch materials or where soil conservation is essential. o Plant residue mulching: ▪ Uses leftover crop parts (e.g., straw, stalks, leaves, husks) as a protective layer. ▪ Sustainable and cost-effective. ▪ Enhances soil fertility and reduces reliance on external inputs. Benefits (Impact): • Creates a physical barrier by covering the soil surface. • Blocks sunlight from reaching weed seeds → inhibits germination and growth. • Thick mulch layer suffocates small/emerging weeds. • Fills soil gaps, leaving less space for weeds to establish. • Prevents weed seed dispersion via wind/water. • Maintains consistent moisture, discouraging weeds that thrive in dry conditions. • Stabilizes soil temperature to prevent germination of weeds adapted to fluctuations. Protocol: • Remove large weeds manually or with shallow tillage. • Use crop residues like straw, husks, or leaves as by-products to minimize costs. • Material should decompose naturally, enriching the soil with organic matter. • Examples: Legumes (cowpea, mung bean), cereal residues (wheat, rice straw). • Use residues that effectively block sunlight (e.g., maize stalks, sugarcane leaves). • Ensure residues are pest- and disease-free.
  • 54.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 • Avoid residues with toxic compounds (e.g., walnut, eucalyptus leaves). • Select biomass-rich crops for thick, uniform mulch (e.g., sunflower stalks, sorghum, pigeon pea). • Choose residues suited to local soil and climate (e.g., grass clippings in tropics, straw in temperate zones). • Residues from nutrient-rich crops (e.g., groundnut, chickpea) can enhance fertility. • Consider crops with added benefits (e.g., erosion control, moisture conservation, beneficial microbes). • Apply 5–10 cm thick mulch; adjust based on material type. • Leave 3–5 cm gap around stems to prevent rotting/pests. • Spread mulch evenly to avoid patchy coverage. 2. Mixed Cropping Brief Description: • Age-old practice of cultivating two or more crops simultaneously on the same land. • Aligns with natural farming principles: ecological balance, biodiversity conservation, low-input farming. • Uses natural symbiotic relationships between crops to maintain productivity without synthetic inputs. Benefits (Impact): • Combines crops with different growth patterns (e.g., tall + spreading) to shade soil and limit sunlight for weeds. • Example: Maize (vertical) + cowpea (spreading). • Efficient nutrient use leaves fewer resources for weeds. • Varied rooting depths exploit water differently, depriving weeds of moisture. • Combined root systems occupy soil niches, preventing weed establishment. • Some crops release allelochemicals (e.g., mustard, sorghum) that inhibit weed germination/growth. • Crop residues after harvest act as natural mulch. • Crop diversity disrupts weed species lifecycles and alters microclimate to affect weed seed germination/viability. Protocol: • Ensure crops have complementary growth habits and resource needs.
  • 55.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 • Use suitable row ratios (e.g., 2:1, 4:1) for maximum coverage. • Synchronize sowing to establish canopy early for weed suppression. • Monitor fields in early stages to address weeds promptly. • Grow crops with varied root depths, canopy structures, and growth habits. • Grow different family crops to break weed cycles and change microclimate. 3. Crop Diversification Brief Description: • Sustainable natural farming approach to foster ecosystem health, optimize resource use, and improve resilience. • Enhances productivity while reducing environmental footprint. Benefits (Impact): • Different crops use different sunlight, water, and nutrients, limiting resources for weeds. • Tall crops (e.g., maize) shade soil; ground-hugging crops (e.g., legumes) cover soil. • Dense canopy prevents sunlight from reaching weed seeds. • Allelopathic crops (e.g., mustard, sorghum, sunflower) inhibit weed germination. • Crop rotation breaks weed lifecycles and prevents resistance. • Varying root depths occupy different soil layers, reducing weed establishment. • Example: Legumes (shallow roots) + maize/sunflower (deep roots). • Reduced soil disturbance in diversified systems prevents weed seeds from being exposed to favorable germination conditions. • Example: Cover crops in rotation suppress weeds by maintaining continuous cover. Protocol: • Understand local soil, climate, water, and pest pressure. • Select crops with complementary growth patterns. • Ensure crops differ in nutrient, water, and sunlight needs. • Include allelopathic crops in the system. • Design rotations alternating legumes and cereals. • Use appropriate crop density for optimal canopy formation. • Choose crops with staggered maturity periods for continuous coverage. 4. Cover Crops Brief Description:
  • 56.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 • Plants grown primarily to cover soil, not for harvest. • Used in natural farming to enhance soil health, manage weeds, and support sustainability. • Typically planted in off-season or between main crop cycles. Benefits (Impact): • Rapid growth forms dense canopies that shade soil, blocking sunlight to weed seeds. • Compete with weeds for water, nutrients, and space. • Some release allelopathic compounds (e.g., mustard, sunflower) to suppress weeds. • Roots disturb soil, making weed establishment harder. • When mowed/decomposed, act as mulch and add organic matter. • Rotation of cover crops disrupts weeds adapted to specific systems. Protocol: • Choose cover crops suited to climate, soil, and weed control needs. • Legumes (e.g., clover, vetch) → add nitrogen + canopy suppression. • Grasses (e.g., rye, oats) → quick coverage + root competition. • Brassicas (e.g., mustard, radish) → allelopathic suppression. • Broadleaf (e.g., buckwheat) → fast growth + smothering foliage. • Plant at right time for maximum suppression. • Ensure dense planting. • Rotate cover crop species regularly. 5. Water Management Brief Description: • Effective water use in natural farming helps control weeds by influencing germination, establishment, and competition. Benefits (Impact): • Timed irrigation (e.g., after crop emergence) reduces weed germination. • Drip irrigation minimizes water for weeds between rows. • Maintains soil moisture optimal for crops, limiting shallow-rooted weeds. • Dry periods can prevent many weeds from germinating. • Wetting/drying cycles can be managed to reduce weeds. • Combining with mulching boosts weed control. • Controlled water levels in wetland systems can suppress invasive weeds.
  • 57.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 Protocol: • Use drip irrigation to deliver water to root zones. • Adjust water to crop needs by growth stage. • Use moisture checks (e.g., feel test, sensors). • Avoid over-saturation that favors weeds. • Apply small, frequent amounts for consistent root zone moisture. • Ensure good drainage. • Schedule irrigation to limit weed germination. • Avoid watering right after weeding or tilling. • Reduce irrigation during warm/moist peak weed growth conditions. • Use rainwater harvesting if possible. • Weed or mulch before irrigating. 6. Use of Weed-Free Seeds Brief Description: • Important to prevent introduction/spread of weed species on a farm. Benefits (Impact): • Prevents weed spread through contaminated seeds. • Avoids replenishing weed seed bank in soil. • Allows crops to grow without resource competition from weeds. • Improves yields and crop health. • Consistent use prevents new weed populations and reduces need for frequent weeding. Protocol: • Choose high-quality indigenous seeds. • Inspect seeds for visible weeds or contaminants. • Clean seeds manually if needed: o Sieving: Removes small weed seeds and debris. o Air Screening: Removes lighter weed seeds and chaff. o Washing: Removes dirt and contaminants. • Store seeds in clean, dry, cool, airtight containers. • Keep storage dark to reduce mold, pests, and weeds. • Clean storage areas regularly. • Ensure soil and environment are weed-free before planting. • Combine with mulching and crop rotation for effective management.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 EXERCISE NO. 12 TECHNIQUES OF INDIGENOUS SEED PRODUCTION – STORAGE AND MARKETING Indigenous seed production in natural farming focuses on preserving local, heirloom, or native seed varieties that are adapted to specific environments, climates, and soils. These seeds are often resilient to pests, droughts, and other stresses without relying on synthetic inputs. Natural farming pioneers like Masanobu Fukuoka and organizations such as Navdanya emphasize community-led systems that maintain biodiversity, crop Vigor, and socio-cultural networks. The process integrates seed selection, production, storage, and marketing to create self-reliant farming systems. Below is an overview based on traditional and sustainable practices. Key Principles 1. Biodiversity and Adaptation: Prioritize seeds with high intra-population variation, selected for resilience to local conditions like drought, floods, and pests. 2. Community Involvement: Farmers, often women and elders, lead selection, exchange, and banking to foster reciprocity and knowledge sharing. 3. Minimal Inputs: Avoid chemicals; rely on natural methods like sun-drying, companion planting, and organic treatments. 4. Sustainability: Techniques aim to reduce genetic erosion, enhance soil health, and support long-term food sovereignty. 5. Integration with Ecosystems: Mimic natural processes, such as using cover crops or polycultures to aid seed production. Techniques for Indigenous Seed Production Production involves selecting, growing, and harvesting seeds from native varieties in ways that maintain genetic diversity and crop health. 1. Seed Selection: o Choose plants that are healthier, taller (20-25% bigger), plumper, and resistant to local stresses. For cereals like maize or wheat, select from robust patches with larger cobs or panicles; thresh by hand and sun-dry. For pulses (e.g., horsegram, pigeonpea), pick from vigorous plants and winnow to remove low-quality seeds. o Methods include mass selection (bulk harvest from superior plants), pure line selection (isolating uniform traits), or class-bulking (grouping similar
  • 59.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 varieties). Farmers use criteria like high yield without inputs, early maturity, and pest resistance across five crop stages (seedling to maturity). o In participatory plant breeding (PPB), collaborate with communities to adapt varieties for organic systems. 2. Field Preparation and Planting: o Use well-drained soils (sandy loams or silt loams) isolated from hybrid varieties to prevent cross-pollination. Control weeds through minimal tillage or summer fallow. o Row spacing: 30-48 inches for species like Arizona cottontop or plains bristlegrass to facilitate cultivation and higher yields. Plant at 25-50 pure live seeds per linear foot, shallowly (0.25-1 inch deep). o Timing: Late summer or spring for irrigated fields; ensure moisture for germination. Incorporate intercropping or polycultures to enhance biodiversity. 3. Harvesting: o Harvest at hard-dough stage for optimal germination; use thumbnail test (seed indents under pressure). Methods: Direct combining for short plants, swathing for shatter-prone species, or mechanical brush/vacuum for large quantities. o For rice, harvest whole panicles; use ratooning or cloning for asexual propagation. Sun-dry post-harvest to 13-14% moisture. 4. Fertilization and Weed Control: o Avoid nitrogen during establishment; use phosphorus if soil tests indicate need. For established fields, apply natural fertilizers like compost. o Mechanical inter-row cultivation (1-2 inches deep) or hand-roguing for weeds; promote natural competition. Techniques for Seed Storage Storage preserves viability, preventing mold, pests, and genetic degradation. Aim for cool, dry conditions (temperature + humidity < 100). 1. Drying: o Naturally sun-dry seeds to 10-15% moisture; use warm air (<108°F) for bulk. Smoke treatment for some vegetables. 2. Containers and Methods: o Traditional: Clay pots, earthenware, calabashes, or handcrafted vessels

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 sealed with mud, neem leaves, ash, sand, or matchsticks for pest control. Store on shelves to avoid moisture. o Vacuum sealing for tropical climates; wooden boxes or soil pits for tubers like potatoes. o Community Seed Banks: Store orthodox seeds (e.g., rice, maize) at room temperature or controlled (0-10°C active, -20°C base). Digital documentation via apps for traits and knowledge. 3. Duration and Monitoring: o Viability lasts 3-6 years under ideal conditions; check regularly for infections. Regenerate in similar environments if needed. Techniques for Marketing Marketing focuses on value addition, community networks, and niche markets for organic, heritage seeds. 1. Community Exchanges and Loans: o Exchange within villages or networks; return with 20-25% interest to account for losses. Seed loans via cooperatives foster reciprocity. 2. Cooperatives and Sales: o Form Farmer Producer Organizations (FPOs) for local/online sales, organic markets, or festivals. Package as "climate-smart" or "heritage" with certifications. Value addition: Process into grains or products for revenue. 3. Seed Tourism and Digital Platforms: o Promote villages via trails, festivals, and workshops; generate income for conservation. Use online databases (e.g., Genesys) for global access. 4. Contracts and Niche Markets: o Secure contracts with agencies for restoration; certify for purity to enhance marketability. Advantages • Resilience: Indigenous seeds reduce input costs and improve yields in changing climates. • Biodiversity: Preserves genetic diversity, supporting food sovereignty. • Economic: Low-cost methods; marketing creates income through cooperatives. • Cultural: Strengthens community networks and traditional knowledge.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 EXERCISE NO. 13 PARTIAL AND COMPLETE NUTRIENT AND FINANCIAL BUDGETING IN NATURAL FARMING Partial and Complete Nutrient and Financial Budgeting in Natural Farming Natural farming prioritizes sustainable, low-input systems that enhance soil health, biodiversity, and self-sufficiency without synthetic chemicals. Nutrient budgeting in this context assesses the balance of essential elements like nitrogen (N), phosphorus (P), and potassium (K) through natural cycles, while financial budgeting focuses on minimizing costs and maximizing returns via local resources. These tools help farmers evaluate efficiency, identify imbalances, and make informed decisions. Below is an expanded overview drawing from organic and zero-budget natural farming (ZBNF) practices, incorporating additional data from case studies and research. In ZBNF, nutrient sources include microbial inoculants, mulching, and crop residues, aiming for a closed- loop system where 98-98.5% of plant nutrition comes from air, water, and sunlight, and only 1.5% from soil. Budgets can be partial (simplified) or complete (comprehensive), applied at field, rotation, or farm levels. Nutrient Budgeting in Natural Farming Nutrient budgeting quantifies inputs (e.g., atmospheric deposition, biological fixation, manures) and outputs (e.g., crop removal, losses via leaching) to maintain soil fertility. In natural farming, it aligns with principles like using Jeevamrutha (microbial cultures) and mulching to recycle nutrients. Additional research highlights the role of nutrient budgets in quantifying sustainability across scales, from plots to national levels, with challenges in measuring terms like gaseous losses or internal transfers. For instance, in East African mixed farming systems, field-scale budgets revealed N surpluses of 10- 30 kg/ha in high-input fields but deficits in low-input ones, emphasizing the need for legume integration. Key Principles • Focus on Sustainability: Emphasizes biological fixation (e.g., legumes fixing 100-200 kg N/ha in clover leys), minimal external inputs, and reducing losses through cover crops and no-till. In organic farms, farm-gate budgets assess N, P, K, S, and Mg, showing surpluses (e.g., +20 kg N/ha) in livestock-integrated systems but deficits in stockless ones. • Nutrients Considered: Primarily N, P, K; secondary macronutrients (Ca, Mg, S)
  • 63.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 and micronutrients (e.g., Zn, Cu) in detailed assessments. • Data Sources: Farm records, soil tests, published tables (e.g., nutrient content in manures, crops), and lab analyses. Partial Nutrient Budgeting This simplified approach compares major inputs and outputs without accounting for all losses (e.g., erosion, runoff) or additions (e.g., sediment deposition), making it practical for quick assessments. It's useful in natural farming for monitoring harvested nutrients vs. applied organic matter. In maize-based systems under low-external-input farming, partial budgets showed N balances of -5 to +15 kg/ha, with improved efficiency from intercropping. • Methods and Calculations: o Steps: 1. Measure crop yield (e.g., dry matter in tons/ha). 2. Determine nutrient removal using concentrations (e.g., % N in crop) and formulas like: Nutrient removal (kg/ha) = (Concentration % / 100) × Dry matter yield (kg/ha). 3. Sum inputs (e.g., manures, fixation) and subtract removals: Budget (kg/ha) = Inputs - Removals. o Applications: For single crops or fields; positive budgets build soil reserves, negative deplete them. In India, partial budgets for primary nutrients indicate national deficits (e.g., -10 to -20 kg K/ha), highlighting overuse of N but underuse of K in natural systems. • Example: In a ZBNF paddy field, partial budget for N might show inputs from Jeevamrutha (providing ~39% of needs) minus crop removal, revealing a deficit if not supplemented by fixation. For alfalfa, removal is ~12 kg P₂O₅/ton dry matter. A potato case study details partial N budgets, estimating removals of 150- 200 kg N/ha based on yield, aiding fertilizer adjustments in organic setups. Complete Nutrient Budgeting This holistic method includes all inputs, outputs, internal flows (e.g., crop residues, manure cycling), and losses, providing a full picture for long-term soil health in natural farming. In forage and grain crops, complete budgets measure removals via sampling, with N losses up to 50 kg/ha from leaching in high-rainfall areas. • Methods and Calculations: o Steps:
  • 64.
    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 1. Record all inputs: Fixation (e.g., 100-200 kg N/ha from clover), deposition, manures (e.g., 50 kg N/ton cattle slurry). 2. Track outputs: Crop off-take (e.g., 150 kg N/ha in wheat), livestock products, losses (leaching ~30 kg N/ha surplus target). 3. Include internal cycles: Residues returned to soil. 4. Calculate surplus/deficit: Surplus (kg/ha) = Total inputs - (Outputs + Losses). o Systems Framework: Covers Soil-Plant, Animal, and integrated systems. In wastewater-agroforestry integration, complete budgets in Jamaica showed nutrient recovery rates of 70-80% for N and P. • Example: On a mixed organic farm (60 ha), complete budget shows N surplus +51 kg/ha, P +1 kg/ha, K -19 kg/ha, guiding adjustments like more legumes for K balance. In German organic farms, farm-gate budgets revealed S deficits (-5 kg/ha) in vegetable systems, recommending sulfur-rich amendments. Comparison of Partial vs. Complete Nutrient Budgeting Aspect Partial Budgeting Complete Budgeting Scope Inputs vs. removals only All inputs, outputs, losses, internal flows Complexity Simple, quick Detailed, time-intensive Accuracy Approximate; ignores losses Comprehensive; accounts for sustainability Use in Natural Farming Monitoring crop-specific needs (e.g., ZBNF deficits) Long-term planning (e.g., rotations) Example Surplus +20 kg N/ha (inputs - harvest) +51 kg N/ha (including fixation - losses) Added Data Example Maize: -5 to +15 kg N/ha in low- input systems Organic farms: S deficit -5 kg/ha in vegetables Financial Budgeting in Natural Farming Financial budgeting plans income, expenses, and cash flows, emphasizing cost reduction in natural farming through local inputs like cow dung and mulching. In ZBNF, it's "zero- budget" as net costs approach zero via self-produced inputs. Case studies from Andhra Pradesh show ZBNF reducing input costs by 9-36%, with yields 1-23% higher, potentially saving Rs. 12,396 crore statewide if scaled. In Karnataka, ZBNF adoption via

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 peasant movements has scaled to millions, with economic benefits from reduced debt. Key Principles • Low-Cost Focus: Eliminate chemical inputs; use on-farm resources (e.g., Jeevamrutha costs ~3-75% less). Partial ZBNF adopters spend INR 4,664/acre on mixed inputs. • Types: Enterprise (crop-specific), whole-farm (overall), cash flow (timing inflows/outflows). • Government Support: Schemes like PKVY (Rs. 12,200/ha over 3 years) aid transitions. Partial Financial Budgeting Assesses marginal changes (e.g., adopting mulching), comparing added revenues/reduced costs vs. reduced revenues/added costs. In soil health case studies, partial budgets showed ROI of 15-30% from practices like cover cropping. • Methods and Calculations: o Steps: List gains (e.g., higher yields) and losses (e.g., new tool costs); calculate net change: Net = Total gains - Total losses. o Applications: Evaluate shifts like herbicide-resistant seeds in natural contexts. • Example: Switching to ZBNF for rice: Gains (22.6% lower costs, Rs. 42,765/ha vs. Rs. 55,286/ha conventional) minus losses (potential yield drop); net +Rs. 12,521/ha if yields stable. In AP, partial budgets for ZBNF showed cost savings of INR 3,000-5,000/acre in initial years. Complete Financial Budgeting Whole-farm or cash flow budgets cover all operations, forecasting revenues (e.g., crop sales) and expenses (e.g., labor). In climate-resilient ZBNF, complete budgets in Anantapuramu district revealed 20-40% higher net incomes due to diversified cropping. • Methods and Calculations: o Steps: Project inflows (sales, subsidies) and outflows (inputs, labor); monitor monthly cash flow. o Applications: For diversified farms; in ZBNF, aims for zero net (e.g., savings Rs. 300-360 crores statewide). • Example: Andhra Pradesh ZBNF farm: Costs 9-36% lower, yields 1-23% higher, net revenues up, with state savings Rs. 12,396 crore if scaled. A multi-state study showed ZBNF farms achieving net profits 15-25% higher than conventional due

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 to lower subsidies needs. Advantages • Nutrient: Improves soil health, reduces pollution; ZBNF cuts N deficit risks with supplements. Soil health practices yield long-term benefits like reduced erosion costs. • Financial: Lowers debt (e.g., diversified systems economically preferable). Enhances resilience; ZBNF could save fertilizer subsidies in India. Challenges • Nutrient: Initial deficits in ZBNF (e.g., 37-54% yield drops without manure). Data accuracy issues; scaling challenges in variable climates. • Financial: Yield variability affects returns; scaling risks food security. Constraints include knowledge gaps and market access.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 EXERCISE NO. 14 EVALUATION OF ECOSYSTEM SERVICES IN NATURAL FARMING (CROP, FIELD AND SYSTEM) Ecosystem services (ES) refer to the benefits humans derive from ecosystems, categorized into provisioning (e.g., food, water), regulating (e.g., pest control, climate regulation), supporting (e.g., nutrient cycling, soil formation), and cultural (e.g., recreation, education). Natural farming, encompassing practices like organic, regenerative, and agroecological systems with minimal inputs, no-till, and biodiversity enhancement, promotes these services by mimicking natural processes. Evaluation involves assessing indicators through field measurements, economic valuation (e.g., willingness to pay, contingent valuation), and modeling to quantify benefits, synergies, and trade-offs. This overview draws from studies on organic and regenerative systems, often analogous to natural farming, evaluating ES at crop (individual plant/crop focus), field (plot-scale interactions), and system (farm/landscape integration) levels. Evaluation at Crop Level At the crop level, ES focus on direct benefits to plant growth, yield, and quality, emphasizing provisioning (biomass, food) and regulating services (pollination, pest control). Natural farming enhances these through diverse varieties, intercropping, and biological inputs, reducing chemical dependency. • Key Services and Benefits: o Provisioning: Higher biomass for food/feed, e.g., in organic systems, crop yields can match conventional with added resilience. o Regulating: Pollination (e.g., by insects) and biological pest control via beneficial predators; intercropping reduces pest infestations. o Supporting: Nutrient uptake and soil fertility enhancement from microbial activity. o Cultural: Aesthetic value from diverse crops. • Evaluation Methods and Indicators: o Methods: Yield measurements, pollinator surveys, and pest predation rates; economic valuation via minimum support prices for food/by- products. o Indicators: Crop yield (tons/ha), pollinator abundance (e.g., bee

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 visits/plant), pest control efficiency (predation rates), nutrient uptake (kg/ha). For rice in eastern India, provisioning ES (food/by-products) valued at US$1052–1234/ha/year, with biological pest control at US$1.6– 2.9/ha/year. In agroecological systems, win-win outcomes include enhanced wheat yield with erosion control in conservation agriculture. • Data and Examples: In regenerative cereal crops, crop-level ES benefits include $196,504 (Fund I) for biological control, with net benefits of $3,762/acre over conventional. Organic cotton in agroecological systems shows yield enhancements with soil carbon increases. Trade-offs: Lower cereal yields in organic transitions but higher biodiversity. Evaluation at Field Level Field-level evaluation examines plot-scale interactions, including soil health, water management, and biodiversity, with strong emphasis on regulating (erosion control, nutrient cycling) and supporting services (soil structure). • Key Services and Benefits: o Provisioning: Soil fertility for sustained yields; cover crops provide additional biomass. o Regulating: Erosion reduction, water retention, and pest/weed control via cover/intercropping. o Supporting: Soil organic matter buildup, microbial diversity. o Cultural: Scenic beauty from heterogeneous fields. • Evaluation Methods and Indicators: o Methods: Soil sampling (e.g., organic carbon, erosion rates via RUSLE), biodiversity surveys, and water infiltration tests; monetization (e.g., Int.$3453/ha/year for regulating in grasslands). o Indicators: Soil carbon levels (%), water infiltration (mm/hour), species richness (arthropods/plants), erosion loss (tons/ha). In rice fields, soil formation valued at US$2.8 × 10⁻⁸/ha/year, hydrological flow at US$11.4/ha/year. Field robots/drones for real-time data on microclimates. • Data and Examples: Organic farmlands in Taiwan show higher field-level ES values for water purification and soil conservation than conventional. Regenerative fields generate $10.2 million (Fund I) in habitat services, with air quality benefits of $4.9 million net over conventional.

    Mr. M. A.Khedekar Asst. Prof Agronomy COA, Viladghat. Mob. 9403183404 EXERCISE NO. 15 & 16 CASE STUDIES AND SUCCESS STORIES IN NATURAL FARMING AND CHEMICAL-FREE TRADITIONAL FARMING Natural farming and chemical-free traditional farming in India emphasize sustainable practices like Zero Budget Natural Farming (ZBNF), organic methods, vermicomposting, and agroecology, rooted in traditional knowledge and modern ecology. These approaches reduce input costs, enhance soil health, boost biodiversity, and improve farmer incomes while addressing environmental challenges like soil degradation and water scarcity. Below is a compilation of key case studies and success stories, drawn from government initiatives, research, and farmer experiences across states. They highlight transitions from chemical-intensive to natural/organic systems, with quantifiable outcomes where available. Andhra Pradesh: Community Managed Natural Farming (APCNF) Andhra Pradesh hosts the world's largest agroecology program, APCNF, launched in 2018 by Rythu Sadhikara Samstha (RySS). It aims to transition 6 million farmers and 8 million hectares to natural farming, rejecting synthetic inputs in favor of harmony with nature. • Background and Practices: Farmers use peer-to-peer extension via Community Resource Persons (CRPs), women-led Self-Help Groups (SHGs), and practices like cover cropping, mulching, and bio-inputs (e.g., Jeevamrutha). The whole- village saturation model starts small-scale experimentation, scaling based on results. It integrates economic, environmental, and climate goals. • Impacts and Outcomes: Reaches over 1 million farmers (mostly women) on 500,000 hectares. Net income rises 56–80% in 1–2 years due to lower costs (e.g., 9–36% reduction) and higher yields (1–23% increase). Environmental benefits include 50% water savings, 7-fold earthworm increase, 55% more birds, 66.4% pest reduction, and 29.7–91.1% lower emissions per crop. Government ROI: $6– 8 per $1 invested. Challenges: Labor shortages and 3–5 year behavioral change period. Recognized with the 2024 Gulbenkian Prize.
