Vermicomposting of Coir Pith Waste

Vermicomposting is a simple biotechnological process of composting, in which certain species of earthworms are used to enhance the process of waste conversion and produce a better end product. Coir pith wastes were collected and analyzed for their physico-chemical properties. The result clearly revealed that the collected Coir pith waste was high potential for using as an organic manure. The physico-chemical parameters, NPK content and nutrient contents were studied. The results showed that pH was bought down to neutral state by vermicomposting and electrical conductivity was also reduced effectively. The NPK content and nutrients were rich in the treatment T4 (Coir pith waste + Cow dung + Pleurotus sajor-caju + Earthworm) followed by the treatment T3 (Coir pith waste + Cow dung + Pleurotus sajor-caju) and T2 (Coir pith waste + Cow dung). Least NPK content and nutrients were recorded in the treatment T1 (Coir pith waste alone). The treatment T4 showed maximum efficiency on 90 days of incubation rather than 120 days of incubation due to the maturity of compost, there are no carbonic compounds to be break down and used for inoculated metabolism.
