 Introduction
Definitions
ORGANIC FARMING is a system of farm design and management to create an eco
system, which can achieve sustainable productivity without the use of artificial external
inputs such as chemical fertilizers and pesticides.
Organic farming is agriculture that makes healthy soils, healthy plants, healthy
food and healthy environment along with crop productivity.
Cont..

 Many people think that traditional agriculture, sustainable
agriculture etc. are synonyms to organic farming.
 Some people are of the view that the use of organic manures
and natural methods of plant protection instead of using
synthetic fertilizers or pesticides is organic farming.
 The organic farming in the real sense is a comprehensive
management approach to improve the health of underlying
productivity of soil.
(Neerja Kapoor and Prahland kumar, 2018,)

What is organic farming
“Organic agriculture, a holistic system that focuses on improvement of
soil health, use of local inputs and relatively high intensity use of local
labor, is a admirable fit for dry lands in many ways and the dry land
offer many benefits that would make it relatively easy to implement.”
-Dr. A.P.J. Abdul Kalam

 Components of Organic Farming (Source: http://agritech.tnau.ac.in/org farm/orgfarm introduction.html)

 CONCEPT
 The concept of organic agriculture has been received differently by different people. to
most of them, it implies the use of organic manures and natural methods of plant
protection instead of using synthetic fertilizers and pesticides.
 The term organic farming describes system that works to mimic and optimize the
natural process for the production of agricultural crops (kepper, 1998).
 Organic growers utilize a wide range of cultural practices and natural inputs to
manage crops in a manner, they consider safe for environment and consumer. the use
of synthetic pesticides and fertilizers is minimized or where necessary avoided.
Cont…

 Organic farming encompasses adoption of some common practices and
agronomic aspect like crop rotation, composting, use of livestock
manure, organic farming can improve the soil by lowering bulk density,
and they can reduce soil erosion and improve soil fertility.
 organic matter encourages the formation of crumb soil structure, thus
improving soil drainage, infiltration, and aeration.

 Scope of organic farming
 Only 35 percent of India's total cultivable area is covered with fertilizers
where irrigation facilities are available and in the remaining 65 percent of
arable land, which is mainly the rainfed negligible amount of fertilizers
are being used.
 Farmers in these areas often use organic manure as a source of
nutrients that are readily available either on their own farm or in their
locality.
Cont…

 The north eastern region of india provides considerable opportunities for
organic farming due to least utilization of chemical inputs.
 It is estimated that a million hectares of such lands available in which can
be exploited for organic production.

 Importance of organic farming
 Organic agriculture can become low cost, sustainable option of
farming in the country, particularly by the small farmers in rain fed
areas and helps to improve their food and income security.
 It helps to produce and supply adequate safe and nutritious food to
the producers and consumers of the nation.
Cont…

 Environmental benefits, health aspects and farmers empowerment are
other important factors influencing farmers to shift to organic agriculture.
some of the important benefits of organic farming are organic fertilizers
are completely safe and does not produces harmful chemical
compound.

 Characteristics of organic farming
 Maximal but sustainable use of local resources.
 Minimal use of purchased input, only as complementary to local resources.
 Ensuring the basic biological functions of soil water nutrients humus
continuum.
 Maintain a diversity of plant and animal species as a basis for ecological
balance and economic stability.
 Creating an attractive overall landscape which gives satisfaction to the local
people.
 Increasing crop and animal diversity in the form of polyculture, agroforestry
systems, integrated crop/livestock systems, etc. to minimize risk.

 Aims of organic farming
 Sustainability of natural resources
 Minimizing the cost of cultivation
 Healthy food
 Augmentation of policy

 Principles of organic farming
 Cyclical principle
 Cyclical principle number one discuss is a close recycling or the
crop cycle. so, we have to grow the one crop after another from
the different groups the same crops should not be repeated
season after season.
Cont…

 Precautionary principle
 The second principle is precautionary principles; that means the better
safe than sorry; that means, prevention is better than cure. so, we
should not use anything any materials that is not allowed in organic
farming.
 So, it precaution better to have a very safe better to avoid the use of
any chemical insecticides and pesticides that is the precautionary
principles Cont…

 Nearness principle
 Third one if the nearness principles; that means, is a
transparency trust building. so, that is also very important in
organic farming.

 Advantages of the organic farming
 Prevent residues in the food material and also toxic material present in the food
material.
 And also prevent different types of the pollutions
 The foods become healthier natural and tasty
 This type of farming should be eco-friendly should not affect the environment
 We should decrease the soil degradation
 No effect to the biological diversity in the system
Cont…

 Instead of using the artificial fertilizers , weedicides and
insecticides in the organic farming natural fertilizers like bio compost and
other are been used.
 Due to usuage of the natural fertilizers no pollution will occur and no residues
 Organic matter supplies all the essential macro and micro plant nutrients.
 Organic matter improves physico-chemical and biological properties of soil.
 Organic farming improves agro eco-system and helps stopping environmentally
degradation.

 The following products are permitted for use in
manuring/soil conditioning in organic fields
 Farm yard manure, slurry, green manures, crop residues, straw and other mulches
from own farm
 Saw dust, wood shaving from untreated wood
 Plant preparation and extracts, eg. neem cake
 Vermicompost

 Organic agriculture helps
 Improve soil fertility by maintaining and building a fertile living soil through frequent
organic matter inputs in the form of green manures, compost and farmyard manure,
sustained soil cover, crop rotations and intercropping.
 Prevent wind and water erosion of soils through a better, more stable soil structure
and texture, through persistent and diversified soil cover and agro-forestry.
 Improve water infiltration and retention capacity through high levels of organic matter
and permanent soil cover, such as cover crops or mulch, which substantially reduce
the amount of water needed for irrigation.

 Government schemes for the organic farming
 National project on organic farming (NPOF)
 National horticultural mission (NHM)
 National project on management of soil health and fertility (NPMSH and F)

Conclusion
 Organic farming is agriculture that makes healty soils,healty plant,healty
food and healty environment along with crop productivity
 Application of vermicompost as per the recommended dose of fertilizer
decreased bulk density, soil temperature and increased water holding
capacity and porosity of crop
 Application of FYM @10 t/ha to cotton in vertisol recorded lowest bulk
density and highest hydraulic conductivity
 Organic farming achieved stable yield after six year of conversion from
inorganic to organic
 Effect of different organic treatments on yield and economics of various
cropping.
 Use of organic manure has beneficial effet on different growth parameters
Viz; plant hight,no.of branches, and top root length in tomato.
 Organic produce Viz; wheat, rice, grapes,pomegranate,banana fetched good
price in market as compared with non organic produce. Cont…

Use of poultry manure,cow dung decreased PH of soil, increased
