An organic amendment is any material of plant or animal origin that can be added to the soil to improve its physical, chemical and biological properties.
EFFECT OF ORGANIC AMENDMENTS ON DISTRIBUTION, STABILITY AND CARBON CONCENTRAT...Dr. Kashif Bashir
The behavior of different organic manures may vary in soil because of their compositional differences. The basic objective of this study was to examine the fundamental characteristics of the traditional organic manures and their direct effect upon aggregate formation and stability. The organic manures i.e. municipal solid waste compost, farmyard manure and poultry litter were characterized on the basis of total organic carbon, total polysaccharides, microbial biomass carbon, humic and fulvic acid content. A two years field trial was executed by applying each of these manures at four levels i.e. 0, 0.25, 0.50 and 1% of soil organic carbon in a randomized complete block design. Poultry litter dominated in the carbonaceous compounds in its composition and under field conditions its application at 0.25% level significantly enhanced the macro aggregate formation (2-4 and 1-2 mm) which reflected in mean weight diameter (MWD) as 1.48 mm and effective sizes at D10, D30 and D60 (0.0261, 0.099 and 0.732 mm, respectively). The application of MSW compost at 0.25% level significantly improved the MWD of wet aggregates (5.5 mm) and carbon concentration of macro aggregates (2-4, 1-2 and 0.5-1 mm).

Why Soil Conditioner Is Important For Healthy GardeningShivaniPadole
Soil conditioners, also called soil amendments, assist improve soil structure by increasing aeration, water holding capacity, and nutrients. They assist chop up compacted clay soils that lack enough space for air and water, which square measure vital for microorganisms to thrive and for plant roots to grow. They additionally cycle nutrients otherwise sure up within the soil. Soil conditioners embody a spread of merchandise made of many alternative materials, each organic and inorganic. Organic (carbon-based) soil conditioners like Bloom can be made of animal manure, fertilizer from yard waste or food waste, cover crop remnant, biosolids, sawdust, ground pine bark, peat moss, or other materials. Common ingredients in inorganic soil conditioners on the other hand square measure usually mineral-based mostly, like enlarged clay or sedimentary rock and even sand.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
3. Introduction
• A soil conditioner, also called a soil amendment, is a material added to
soil to improve plant growth and health.
• The type of conditioner added depends on the current soil composition,
climate and the type of plant.
• A conditioner or a combination of conditioners corrects the soil's
deficiencies.
• Fertilizers, such as peat, manure, anaerobic digestate or compost, add
depleted plant nutrients.
• Gypsum releases nutrients and improves soil structure.
4. Characteristics of soil conditioners
• Soil conditioners are natural and earthy.
• Absorb water rapidly.
• Compost is “Synthetic manure made from decomposing
materials, fertilizer and soil.
• Leaves and manures are also natural products.
5. Function of soil conditioners
• They help to improve the amount of minerals in the soil.
• Soil that is rich in minerals will produce much healthier vegetation.
• Leaves work by attracting earthworms which create a healthy soil .
• Soil improved by
• Physical
• Chemical
• Biological
6. Importance of soil conditioners
• Soil conditioner is a product which is added to soil to improve the soil
quality.
• Soil conditioners can be used to rebuild soils which have been damaged
by improper management, to make poor soils more usable, and to
maintain soils in peak condition.
• A wide variety of products can be used to manage soil quality, with most
being readily available from nurseries and garden supply stores.
• People can also generate their own soil conditioner with materials from
home.
7. Importance of soil conditioners
• Many soil conditioners are designed to improve soil structure in some
way.
• Soils tend to become compacted over time, which is bad for plants,
and soil conditioners can add more loft and texture to keep the soil
loose.
• They also add nutrients , enriching the soil and allowing plants to
grow bigger and stronger.
• Soil conditioners improve the water retention in dry, coarse soils
which are not holding water well, and they can be added to adjust the
PH of the soil to meet the needs of specific plants or to make highly
acidic or alkaline soils more usable.
8. Soil physical conditions and soil conditioners
• Soil physical condition is one factor that can limit
crop production.
• Poor soil physical condition can restrict water
intake into the soil and subsequent movement,
plant root development, and aeration of the soil.
• These goals can be accomplished in part through
the use of good management techniques.
• Producers and researchers alike are interested in
improving the physical condition of the soil and,
thus, enhance crop production.
9. Vital role of soil conditioners
• Improved soil structure and aeration
• Increased water-holding capacity.
• Increased availability of water to plants
• Reduced compaction and hardpan conditions.
• Improved tile drainage effectiveness
• Alkali soil reclamation
• Release of “locked” nutrients
• Better chemical incorporation
• Better root development
• Higher yields and quality
10. Role of soil conditioners/Amendments under INM
• Soil conditioners may be used to improve water retention in dry,
coarse soils which are not holding water well, and they can be added
to adjust the pH of the soil to meet the needs of specific plants or to
make highly acidic or alkaline soils more usable.
Examples of soil conditioners
• Peat
• Compost
• Coir
• Manure
• Straw
• Vermiculite etc.,
14. Organic Soil ConditionersOrganic Soil Conditioners
• Soil organic matter serves as a reservoir for nutrients;
• Improves soil structure ,
• Drainage,
• Aeration,
• Cation exchange capacity,
• Buffering capacity, and water-holding capacity; and provides a source of
food for microorganisms.
• Generally soils having higher in organic matter have improved soil physical
conditions.
• The effectiveness of organic soil conditioners can be partly evaluated by
examining several properties of soil organic matter.
15. Organic Soil Conditioners
• Soil organic matter is defined as the organic fraction of the soil and
includes plant and animal residues at various stages of
decomposition, cells and tissues of organisms, and compounds
synthesized by the soil organism population.
• Soil organic matter contains a wide array of compounds ranging
from fats, carbohydrates, and proteins to high molecular weight
humic and fulvic acids.
16. Green manureGreen manure
• GM is a crop that is grown mainly to add nutrients and organic matter to the
soil, this kind of crop is used in rotation with other crops, which is ploughed
under to serve the same purposes as animal manure.
• The roots of some green manure grow deep into the soil and bring up nutrients
that are not present in shallow rooted crops.
• Leguminous crops are especially favored as green manures because they add
nitrogen to the soil.
17.
18. The green manure crop should possess the following desirable
characteristics :
• have profuse leaves and rapid growth early in its life cycle.
• have abundance and succulent tops
• be capable of making a good stand on poor and exhausted soils.
• have a deep root system.
• be legume with good nodular growth habit
19. Green manuring
• Supply Organic Matter
• Green manure supplies organic matter to the soil.
• The organic residues from green manure also help to provide the stability
of soil structure needed for optimum plant growth.
• Humus formed from green manure increases the absorptive capacity of
soil, promotes aeration, drainage and granulation, which help the plant
growth.
• Green manuring improves the structure of the soil. Organic matter
stimulates the activity of soil micro-organisms.
• The ability to bind contaminants is exhibited when using organic soil
mulches in construction of filter germs.
20. Addition of Nitrogen:
•The green manuring crop supplies additional nitrogen to organic
matter, if it is a legume crop, which has the ability to fix nitrogen from
the air with the help of its root nodule bacteria (e.g. Rhizobium).
•The legume crop adds nitrogen for the succeeding crop.
•So all the legumes crop leave the soil in better physical condition and
richer in nitrogen content.
•They return the plant nutrients of deeper layers to the upper top soil
Nutrient and Soil Conservation
•Green manuring crops act as cover crop.
21. • They protect the soil from erosion and nutrient loss by taking up soluble
nutrients which might otherwise have been lost in drainage water or due to
erosion.
• Green manuring crops make available phosphorous and other nutrients
fort he succeeding crops.
• Green manure has a marked residual effect also.
• Increases the biochemical activity.
• The organic matter added to soil by way of green manure acts as food for
micro-organisms.
• The organic matter stimulates the activity of micro-organisms and they
stimulate the biochemical changes accordingly.
22. Green manuring increases crop yield:
• Green manure increases the organic matter and nitrogen content
(in case of leguminous green manuring crop) of the soil.
• It is proved that if green manuring is done properly, it always
results in increased yields of the succeeding crops.
23. Compost
• Composting is comes naturally to plant materials.
• They return to the earth to supply nutrients for the next cycle of
seeds.
• kitchen scraps can be recycled and yard waste composting them.
• Instead of throwing out produce scraps, egg shells and coffee
grounds, can be compost of along with the leaves raked up and
the dead plants cleared out of the garden.
24. Importance of composting
• Improve the soil quality to reap their benefits and vitality by releasing
the rich nutrients in the compost into the soil
• Prevent greenhouse gas emissions by encouraging the aerobic
breakdown of organic material and reduces the amount of garden and
kitchen waste going to Landfill.
• Recycle valuable nutrients and reduce the use of artificial fertilizers
25. Importance of composting
• Adding raw material to compost
• Vegetable and food scraps
• Fallen leaves (in layers)
• Tea leaves and tea bags Sawdust
• Coffee grounds , Egg shells, Weeds, Wood ash
• Compost and organic soil mulches instead of more conventional
methods sediment control are numerous.
• Probably the two greatest benefits of using compost as a soil mulch in
sediment control
• immediate effectiveness
• its ability to bind and degrade specific contaminants.
26. CompostCompost
• Compost is made by forming
alternate layers of organic matter
and soil, commercially made
fertilizer can also be added to the
compost.
28. Components needed during CompostingComponents needed during Composting
• Decomposition can take place even without these ingredients, but the
process can be slow and unpleasant.
• Vegetables, if decomposed in plastic bag, will develop a foul smell
29. Home compost
• Composting is the controlled decomposition of organic material
such as leaves, twigs, grass clippings, and vegetable food
waste.
• Compost is the soil amendment product that results from proper
composting.
• composting helps to keep the high volume of organic material
out of landfills and turns it into a useful product
31. Application
• General application rates for compost or other organic soil amendments are
based on the salt content of the materials and soil and on the depth to which
it is cultivated into the soil.
• Ideally, cultivate the soil amendment into the top six to eight inches of the
soil.
• On compacted/clayey soils, anything less can lead to a shallow rooting
system with reduced plant growth, lower vigor, and lower stress tolerance.
• Compost, which includes manure or biosolids as a component, has a
potential for high salts
• Excessive salt levels are common in many commercially available products
sold in Colorado.
32. • Compost needs to be thoroughly mixed into the upper six to eight inches of the soil
profile.
• Do not leave compost in chunks, as this will interfere with root growth and soil
water movement.
• As the soil organic content builds in a garden soil, the application rate should be
reduced to prevent ground water contamination issues.
• A soil test is suggested every four to six years to establish a base line on soil
organic matter content If using a green manure cover crop, till the cover crop in
before it reaches four inches in height.
• In the vegetable garden do not plow in woody materials such as bark or woodchips.
• They may interfere with seedbed preparation and may result in soil nitrogen
depletion.
33. Benefits of composting
• Compost that are stable in nature, possessing significant amounts
of humic acids, have the ability to bind nutrients and heavy metals,
as moisture passes through the product layer.
• Organisms found within compost have the ability to degrade organic
contaminants such as hydrocarbons found in petroleum based
materials.
• Green manure:
• The practice of ploughing or turning into soil under-composed green
plant tissue for the purpose of improving physical condition as well
as fertility of the soil is referred to as green manuring and the
manure obtained is known as green manure.
35. Crop Residues
•Crop residues contain substantial
quantities of plant nutrients.
Recycling of plant nutrients
•Soil moisture temperature regimes,
enhancement of soil structure,
erosion control
36. Crop Residues
• Leaves make dark, rich
compost that add nutrients to
your soil and help keep your
plants strong and disease
free.
• Fall cleanup is a great time to
start a compost pile and put
those leaves to work.

38. Coconut shell mulch
• The mulching made from the
grinding up of coconut shells.
• its is extremely long lasting since
it comes from a tropical plant and
decomposes very slowly;
39. Coconut shell mulchCoconut shell mulch
• It has a very strong but pleasant odor which is suppose to keep
bugs and animals (dogs and cats) away from the plants it is
mulching.
Other Organic Fertilizers
• Include bird and bat droppings, blood meal, bone meal, and
fish meal.
40. Coconut shell mulchCoconut shell mulch
• All these substances contain nitrogen and other
essential elements
• Bone meal is an excellent source of the element
phosphorus.
• But blood meal, bone meal, and fish meal is seldom
used on farms as fertilizers, because it is too
expensive.

Types of Inorganic soil conditioners
42. Synthetic Binding Agents
• New polymers applied at much lower rates have been
promoted as soil conditioners.
• These polymers include
Natural polysaccharides,
Anionic
Cationic polymers,
polyacrylamides.
43. Synthetic Binding AgentsSynthetic Binding Agents
• The compounds are very high
• molecular weight,
• long-chain polymeric,
• organic compounds,
• which bind particles together and form stable
aggregates
44. Mineral Conditioners
• Gypsum has long been recognized for its benefits on
high sodium-containing soils.
• Gypsum is a mineral with the chemical composition
CaSO4 * 2H2O.
• It occurs in nature as soft crystalline rock and varies in
purity.
45. Mineral ConditionersMineral Conditioners
• Gypsum has been shown to displace exchangeable sodium from the
cation exchange sites of soils high in sodium
• With irrigation or dryland, gypsum can be used to reclaim saline
areas or slick spots, soften and crumble alkali hard pans, supply
calcium on low exchange capacity soils, and improve infiltration for
some puddled soils.
46. Mineral ConditionersMineral Conditioners
• Gypsum is not recommended on soils containing native gypsum
or areas irrigated with water containing abundant amounts of
calcium and magnesium
• The amount of gypsum to apply depends on the purity of the
gypsum and the quantity of sodium present in the soil.
• Actual rates should be based on a salt-alkali soil test.
47. GypsumGypsum
• Lowers bulk compactness of soil
• Prevents water run-off and eroding
• Betters Soil Composition
• It affords root growth and air and water movement.
• Converts Salty Soils
48. GypsumGypsum
• An economical method to resolve salty soils.
• Ties Organic Matter to Clay
• The importance of organic matter is magnified when it is
dispensed with gypsum.
• Soil crusting is impossible and then helps seed emersion.
49. GypsumGypsum
• No crust formation allows more and faster seed emergence
and a couple days earlier to harvest and market.
• Betters low dissolved matter Irrigation Water
• Develops water use efficiency
50. GypsumGypsum
• Gypsum helps the efficiency use of water for the crops. In
periods of drought, this is exceedingly important.
• Helps moist soils to be tilled easier
• Less energy is required for the tillage
51. Quantity of gypsum applied in mineral soil conditionersQuantity of gypsum applied in mineral soil conditioners
• 10 tons/acre.
• Gypsum applied at less than 500 pounds per acre
• Limestone, crushed rock, and other products high in calcium and/or
magnesium which improve the physical condition of some soils, when
applied at several tons per acre.
52. Let Us Sum Up
• Soil conditioners to improve agricultural land and increase productivity.
• Types of soil conditioners and their role , importance , function and
usage are described.
•Farmers can adopt this technology to improve the crop production.
