Background
Organic farming is a system where readily soluble, synthetic fertilizer and biocides are avoided during cultivation. It relies on crop rotation, crop residues, animal manures, particularly vermicompost, legumes, green manures, and biological pest control to maintain soil productivity and tilth. Organic farming is recommended because the present chemical and machine dominated agriculture practice has resulted in i) loss of natural habitat and species of flora and fauna, ii) pollution of ground and surface water, iii) damage of soil structure, iv) reduced fertility of sol, v) health hazards in food, vi) reduction in food quality, vii) waste of energy since it is an energy intensive system, ix) economically costly. On the contrary organic farming maintains the ecological balance, enhances soil structure, tilth and quality of food and is economically cheap.
Tamil Nadu has total cropped area of about 6.63 mha with the diversified crops as rice, cotton, sugarcane, pulses, fruits, flowers and vegetables of which 10% of the area can be brought under organic farming with the available resources. There had been a decline in soil organic matter from 1.20 % in 1970s to 0.68 % in 2000. Organic matter content is usually used as an index of soil health, since it influences the soil in three ways, such as, physically, chemically, and biologically. Crop residues and animal dung are good sources of organic wastes to improve the organic matter content in the soil. In Tamil Nadu 200 lakh tones of crop residues and 300 lakh tones of animal dung are available. These wastes can be composted and good organic manure will be obtained. Composting is allowing organic materials to decompose under more or less controlled conditions to produce a stabilized product that can be used as a fertilizer and/ or soil amendment. Daily around 75 tonnes of municipal solid waste is generated in each block. From the bio-degradable waste (45%) 16.75 tonnes of organic manure will be produced on 60th day . Annualy 5000 tonnes of organic manures produced in each block.
Project Rationale
The awareness of organic farming is lacking among the farmers. It is the need of the hour to switch to sustainable farming from intensive farming. Organic farming practices gives the opportunity to the farmers to use all the organic resources available for crop production instead of depending only on chemical fertilizers. In the solid waste management, large quantities of organic wastes are not fully utilized. for manure making. Most of the wastes are either burnt or discarded openly. If all the wastes are fully utilized for manure making large quantities of organic manure will be available for use and the environment will be very clean. So a model is necessary to educate the farmers to learn things. By utilizing all the organic manures it is possible to supply 2.1 lakh tonnes of nitrogen, 1.2 lakh tonnes of phosphorus and 2.7 lakh tonnes of potassium.
Farmers and self help groups will be trained in 129 blocks of 9 districts (Salem, Dharmapuri, Krishnagiri, Namakkal, Perambalur, Dindigul, Ramanathapuram, Coimbatore and Villupuram) on organic farming and organic manure production and establishment of vermicompost unit, model municipal waste composting unit and bio-inputs production units. The trained farmers / self help groups will start doing organic farming and organic manure production units as well as bio-inputs production units. This will serve good source of organic inputs in those areas.
- To impart training on organic farming to farmers/ SHGs
- To impart training on organic manure production to farmers/ SHGs
- Establishment of vermicompost model units in farmers holding and municipal waste composting units and bio-inputs production units at block level

f |
Inputs |
|
i. Resource material on organic farming practices for ready reference |
g |
Implementation arrangements

- TNAU: Imparting training
|
h |
Data sources and monitoring evaluation
TNAU will monitor the organic farming and get the database on organic farming for different crops. |
5.2 |
Training on organic manure production |
a |
Purpose
To create awareness among the farmers about organic manure production and motivating them to produce organic manures. |
b |
Objectives
Organic manure production should be increased in Tamil Nadu by utilizing all the wastes generated in farmers’ field. |
c |
Outputs
More organic production units will be established at block level and large quantities of organic manure will be utilized for farming. Due to this organic content will be increased in the soil and soil health is improved |
d |
Performance targets
The farmers and self help groups will understand the science of utilizing all the bio-degradable waste for agricultural production |
e |
Activity
In each block 100 farmers identified by department of agriculture will be trained on organic manure production and all the literatures on organic manure production will be given to them for practices. The interested farmers who have decided to adopt the organic manure production will be given periodical counseling. |
f |
Inputs |
|
i. Resource material on organic manure production will be given to farmers for practicing organic manure production. |
g |
Implementation arrangements
i) Department of Agriculture: Selection of farmers and self help groups
ii) TNAU: Imparting training |
h |
Data sources and monitoring evaluation
TNAU will keep in touch with organic manure producers and give advisory and technical support for quality organic manure production |
5.3 |
Establishment of vermicompot units, municipal waste compost units and bio-inputs production units |
a |
Purpose
To motivate the farmers, SHGs and NGOs to start their own production units at block level for organic manure production and bio-inputs production. |
b |
Objectives
All the farm waste generated will be fully composted and put back to the field for organic matter content increase.
All the biodegradable municipal solid waste generated will be composted and make it as manure
At block level bio-inputs production units will start functioning |
c |
Outputs
More organic manure production units will be established at block level and large quantities of organic manure will be utilized for farming.
There will not be any accumulation of municipal solid waste at block level and more manure will be available for use
All the bio-inputs will be available in large quantity at block level |
d |

One SHG will start doing the municipal waste composting in each block
One SHG/ NGO will do the bio-inputs production unit in each block |
e |
Activity
In each block 5 farmers identified by department of agriculture will be given 50% subsidy to establish the vermicomposting units
At block level one SHG will be identified and 50% subsidy will be given to establish municipal waste composting unit
At block level one SHG / NGO will be identified for getting 50% subsidy for starting bio-input production unit |
f |
