1. BIOMASS ENERGY FROM AGRICULTURAL WASTE
Agricultural waste products are gathered and used as fuel for energy
production. In the power plant, the biomass is used as efficient fuel for
energy production which is fed into the regional power supply system.
Agricultural waste products are gathered and used as fuel for energy
production.
Biomass waste streams are potential feed
stocks for a variety of products ranging
from the production of fuel, polymers and
building products.
Agricultural biomass wastes/residues are
predominantly crop stalks, leaves, roots,
fruit peels and seed/nut shells that are
normally discarded or burned but are in
practice a potential valuable supply of
feed-stock material.
The complex environmental impacts,
including the positive (e.g., biomass
renewability and carbon neutrality) and
negative (e.g., land use change, depletion
of soil carbon and nutrient stocks and loss
of biodiversity and water scarcity)
implications, the use of biomass for energy
production cannot be overlooked.
Renewable bioenergy includes crop-based
bio hydrogen production, e.g., from maize
and sweet sorghum; herbaceous species,
e.g., miscanthus, switchgrass and kenaf
RICE HUSK GASIFIIER
It can be used for thermal applications
in agro industries particularly in Rice
Mills. Its thermal efficiency is 55 – 60%.
NUTRIENT MANAGEMENT IN AGRICULTURE
Nutrient management is the science and practice directed to link soil, crop,
weather, and hydrologic factors with cultural, irrigation, and soil and water
conservation practices to achieve optimal nutrient use efficiency, crop
yields, crop quality, and economic returns, while reducing off-site transport
of nutrients.
Chemical fertilizers are the immediate source of nutrients in the soils.
Micro nutrients are best applied through fortification of major fertilizers.
They have a significant impact on plant growth and life.
Comprehensive and authentic database on micro nutrient/bio- fertilizer
production and distribution in the State by public and private sectors
needs to be built up for the benefit of all the stakeholders.
TECHNIQUES OF SUSTAINABLE FARMING
• INTEGRATED PEST MANAGMENT(IPM)
• CROP ROTATION
• BIOTECHNOLOGY
• USE OF ORGANIC FERTILIZERS
• CONSERVATION TILLAGE
Sustainable agriculture is the practice of farming using principles of ecology ,the study
of relationship between organisms and their environment. this form of agriculture
enables us to produce healthful food without compromising future generations ability
to do the same.
SUSTAINABLE AGRICULTURAL PRACTICES
IPM is a broad based approach that integrates
sustainable practice for economic control of pests. It
is a careful consideration of all available pest control
techniques and subsequent integration of
appropriate measures that discourages the
development of pest population and keep pesticides
to levels that reduce or minimise the risk to humans
health and environment.
INTEGRATED PEST MANAGMENT(IPM)
CROP ROTATION :
Sustainable practice of growing series of
different types of crops in same area in
sequential seasons . crop rotation gives
various nutrients to soil, it also mitigates the
build up of pathogens and pests that often
occurs when one species is continuously
cropped and also improve soil structure and
fertility.
BIOTECHNOLOGY:
Use of living systems or organisms
to develop or make useful products.
Biotechnology can provide
appropriate new tools for use in
solution of specific problems in
sustainable agriculture.
USE OF ORGANIC FERTILIZERS:
Organic waste are derived from
animal matter or veg matter. The
use of organic fertilizes in
sustainable gardens and farms are
quickly gaining popularity.
CONSERVATION TILLAGE :
conservations tillage is any method of soil cultivation that leaves the
previous years crop residue on fields before and after planting the next
crop.
SUSTAINABLE CROPPING MANAGEMENT METHODS
It is an efficient management system of
renewable resources including soil,
forests, crops, biodiversity and
ecosystem without degradation, to
provide adequate food and other needs
for the current and future generations.
Components of sustainable system.
2. Fauna is all of the animal life present in a particular region or time. The corresponding
term. For plants is flora. Flora, fauna and other forms of life such as fungi are collectively
referred to as biota.
• Higher Concentration of Mammals is found in the region of this villages. Mammals especially
cows,monkeys,cats are found in higher numbers in the village.
• Various varieties of birds are also found in this village,espicially three types of hens and cocks are
locally spotted in the region.
• As the village mostly has dense thick patch of landscape covers trees and foliage, a large variety
of snakes and other reptiles are predominantly spotted in the village.
• Due to vast extent of rivers in the region, fishes are available in plenty for both aesthetic as well as
commercial purposes. Most of the fishes caught there are sold in the market and are helpful for
improving livelihood.
• Certain variety of amphibians are found in the region such as frogs and tadpoles.
• Cow and buffalo have found to given higher
• Economy gains to the community due to
• The good production of milk.
• Goats have been breaded locally and sold in
• Local markets
• The hen farms has found to given good source
• Of egg sand meat.
• Cow and buffalo have found to given higher economy gains to the
community due to the good production of milk.
• Goats have been breaded locally and sold in local markets.
• The hen farms has found to given good source of eggs and meat a long
with the meat rendered from goose and duck
• The cow prefers Blue grass, Bermuda grass, rye, wheat, and
corn. A cow will often try to eat plants like grass at first
before moving on to greener.
• hens main feed for Chickens Alfalfa meal, corn ,field peas
,wheat.
• Goats will eat hay, grasses, weeds, grain, and sometimes
even tree bark.
• The main diet for the buffalo is roughage such as grass,
legumes and straw.
