- Problem /need addressed by technology developed:
As far as organic farming, application of quality inputs at appropriate time would contribute to increase in yield of crops. Vermicompost is one such input adopted by organic farmers. Commercially, this is not available in all fertilizer shop. This made us think to develop a model - Community Vermicompost Unit where farmers can get good quality vermicompost and it serve as income generation source for the community. Secondly, making of vermicompost can be done by using locally available raw materials. These raw materials include cattle dung or leaf compost. This organic manure is available within the vicinity of the rural women.
- Description / specification of technology developed:
This is the community owned enterprise where farmers can buy the inputs at lesser cost, this unit serves as input facilitation centre for quality organic inputs in Nagapattinam District. e.g, Biofertilisers, biopesticide are also available for sale.
Vermicompost is the result of treatment of such low quality organic manure (high C: N ratio) and converting them into high quality organic manure (low C: N ratio). The quality of organic manure is inversely proportional to the C: N ratio of the manure. This process of conversion is made possible by earthworms which digest organic manure and the entire process of conversion is completed for one batch within 30 days.
The final produce in the form of vermicompost is a moist granular produce which can release nutrients immediately to crops, unlike raw organic matter, which needs to be decomposed in the first place.
