Vermi-compost is a measure produced by composting waste materials by using earthworm. Earthworm digest as low as two percent of the food consumed by it and hence excrete about ninety eight percent of food consumed. The excreta of earthworm is always considered as a natural manure. The modern method of controlled feeding and collection of excreta is known as vermin-composting. It has already become a popular process of manufacturing Bio-fertilizer.
With massive propagation of Chemical fertilizer and pesticides in last few decades demerits of such fertilizer and pesticides came into focus of the world. It was found that such fertilizers and pesticides harm not only human health but also the environment and the very soil on which agriculture is done. Alternatives like manure and compost are therefore found to be better fertilizer. Balanced fertilizer can be achieved by vermi-composting where right balance of N.P. and K can be ensured.
Other natural fertilizers find it difficult. Thus vermi-compost is one step ahead in natural fertilizers. By mixing Neem and Tobacco extracts with others vermi-compost can be made to serve properties of fertilizer as well as pesticide.
