A Review on Vermicompost Enrichment: In Prospect of Village Level

Cow dung is very useful as fertilizer, with help of earthworms a unique product vermicompost is formed. Importance of vermicompost over chemical fertilizer is accepted by all. There is plenty of cow dung but vermi tank are limited, here we have discussed some innovations to fasten the process of maturation by using decomposer, bacteria and fungi species, here we have reviewed different methods. It found significantly higher phosphorus percent in slurry method, slight more K percent compare to conventional method, not much difference in N content are reported, almost two folds increase in useful bacteria fungi and azotobacter population are recorded as compare to conventional. There are reported increase in N and P contents of manure after inoculation of phosphate solubilizing bacteria (PSB) and N-fixing bacteria. Waste decomposer which contains fungi Trichoderma viridae and strains of bacteria Pseudomonus fluorescence and Azotobactor chroococcum also impart positive effects on nutrients composition in manure and also a symbiosis effect on earthworm population. The method of Pile composting enriched with decomposer will be prove as very useful for huge quantity waste with less resources and time.
