2. Description of the SLM Technology
2.1 Short description of the Technology
Definition of the Technology:
The use of city compost is a sustainable solution for addressing the problem of waste management and soil degradation. Under this technology, urban municipal waste is composted and used as organic fertiliser in agriculture. This relieves the cities’ waste management, enhances rural soils and in turn improves farm productivity.
2.2 Detailed description of the Technology
Description:
In India, over 377 million people live in almost 8,000 cities or towns. They generate 62 million tons of municipal solid waste annually, according to the country’s government. More than 80% of such solid waste is deposited indiscriminately without treatment at dump yards in an unhygienic manner. In the Indian countryside, the ecological sustainability of agriculture has been at risk due to the excessive use of chemical fertilizers and monoculture since the ‘Green Revolution’ led to the degradation of land.
City compost is one of the solutions to both problems. Waste collected by municipal corporations is processed to make compost. During this process, organic waste is collected in the cities, recycled, processed to compost, and finally used as organic matter by farmers complementing the traditional farmyard manure. In such manner carbon that is contained in the waste is recycled back into the soil thus enhancing agricultural production.
Nashik Municipal Corporation in Nashik town of Maharashtra State in India has set-up a waste processing plant in the town. This plant processes the city’s organic waste into compost through a scientific process. The processed city compost is packed into bags of 50 kg each and these bags are supplied to fertilizer companies and further on to farmers. There are Government subsidies available to farmers for the purchase of compost bags subject to documentary proofs and other conditions.
Under the “Soil Protection and Rehabilitation for Food Security (ProSoil)” project of GIZ, farmers and FPOs (farmer producer organizations) have been supported for the application of city compost in their fields. Supported by the implementing agency WOTR (Watershed Organization Trust) the city compost application in farmer's fields in 3 districts of Maharashtra namely Ahmednagar, Jalna and Dhule has been introduced. Interventions covered more than 3000 farmers and around 1100 Acres of land. The entire intervention is implemented with the help of FPOs, which procured the city compost from ‘The Nashik Waste Management Centre’ and sold the procured material further to the farming communities. This has ensured easy availability to the farmers without incurring undue travel cost. Farmers applied the city waste compost in their farms during the month of May/June (before the onset of monsoon) to different crops.
City compost was applied to different crop combinations such as paddy-chickpea in Dhule District (moderate irrigation facility), greengram-sorghum in Ahmed Nagar District (Rainfed conditions) and soyabean-wheat in Jalna District (irrigated conditions). Farmers have seen the benefits of city compost across all crop combinations and geographies. The application of city compost has been of benefit to farmers in reducing the usage of synthetic fertilizers along with reducing the dependency on farmyard manure as it is getting scarce day by day. Farmers have also realized the improved soil health leading to better productivity of their farms.
The Indian government has also launched several initiatives to promote the use of city compost in agriculture. For example, the National Mission for Sustainable Agriculture provides financial assistance to farmers for the purchase of city compost, and the Fertilizer Control Order allows the use of city compost as a fertilizer. Although developing city waste as compost and its application in the farmer's field is a nascent approach from the India Government and other stakeholders, however looking at the availability of waste, the commitment of the Indian Government through its ‘Clean India Program’ and the vast issue of synthetic fertilizers usage and high subsidy burden, the use of city compost in agriculture has the potential to contribute to sustainable solutions in the area of waste management while improving soil health and reducing the use of synthetic fertilizers in India.

No
6.7 Strengths/ advantages/ opportunities of the Technology
Strengths/ advantages/ opportunities in the land user’s view |
---|
A good replacement for farmyard manure (dung) as its availability is a challenge due to reduction in numbers of livestock |
Improved productivity of major crops |
Farmers have observed improvement in soil moisture and soil texture which indicates a better soil health |
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view |
---|
This is an excellent mechanism to promote the waste management and address this long-standing problem of the country |
An economically cheaper option to meet the composting needs of farmers thus promoting the natural farming |
A good business line for FPOs as city compost is generally not available in the market |
In the longer run, regular application of compost can improve the soil organic carbon |
6.8 Weaknesses/ disadvantages/ risks of the Technology and ways of overcoming them
Weaknesses/ disadvantages/ risks in the land user’s view | How can they be overcome? |
---|---|
Currently available in Nashik city only which is 150 km from the project area | Collective procurement by FPO and selling it to its members |
Prices of city compost are very high at the non-subsidised prices | Farmers can keep their documents updated to get the subsidised compost. Also put up an application to concerned authorities for continuation of subsidy. |
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view | How can they be overcome? |
---|---|
Regular supply from the waste processing plants. Many such plants do not operate regularly due to internal and external reasons. | FPOs can undertake some longterm contracts with the company. Also in the long run they can set-up small plants for local-level composting. |
