Abstract

In this present study, Jatropha Carcus cake, a by product from the bio diesel production process was destabilization through vermicomposting to produce bio fertilizers. Jatropha Curcas cake was vermicomposted over a period 30 days using Eisenia Fetida earthworms. The nitrogen, phosphorous and potassium (NPK) content in the cake was continuously monitored using AOAC methods and the same was done for the leachate (vermiwash) produced during the vermicomposting process. The NPK content in the Jatropha Curcas cake increased with increase in the vermicomposting period with a 35% increase in N, 58% increase in P and a 98% increase in K. Furthermore, the vermiwash produced had an NPK with a composition of 2.1%, 0.75% and 0.51% respectively. The bio stabilization of the Jatropha Curcas cake through vermicomposting to bio fertilizers.
