Bioconversion of Biogas Slurry into Eco-Friendly Manure by Vermiculture Using the Earthworm Species Eudrilus eugeniae

Bioconversion of organic waste materials into nutritious compost by earthworm activity is an easy and effective way of recycling when it is compared to farmyard waste. Vermicompost is a potential organic manure which contains NPK, micronutrients and enzymes, which have stimulatory effect on plant growth. Eudrilus eugeniae was selected to convert the biogas slurry into vermicompost in this study. The culture was maintained for 45 days. 1^st, 23^rd and 45^th day samples from both control and experimental were taken, dried, sieved, powdered and used for estimation of physical and chemical parameters. At the end of the experiment juveniles and cocoons were observed.
