Chemical analysis of vermicomposts/vermiwash of different combinations of animal, agro and kitchen wastes.

Abstract

2 Abstract: In India million tons of livestock excreta, agro and kitchen wastes are produced every year which are serious problems for society. This work to evaluate the potential of an epigeic earthworm Eisenia foetida to convert the different combination of variety of wastes in to rich nutrient vermicomposts/vermiwash and pre and post chemical analysis of feed mixtures. Vermicomposting results in significant decreased in pH, Total organic carbon (TOC), electrical conductivity (EC) and C:N ratio while significant increase in total Kjeldohl nitrogen (TKN) available phosphorus, exchangeable potassium and calcium in vermicomposts/vermiwash. The increased level of plant nutrients in final products in different organic resources demonstrated that the vermicompost/vermiwash of these wastes will be a valuable biofertilizer for sustainable land restoration practices. This study clearly indicates that vermicomposting of animal, agro/kitchen wastes not only produced a valuable vermicompost/vermiwash but also increased level of plant growth supplements in final vermicompost.
