Management of water hyacinth (Eichhornia crassipes), an aquatic weed waste, by vermicomposting technology
Water hyacinth has become a menace in Sambhaji tank, Solapur city, Maharashtra, India. An attempt has been made to convert this water hyacinth into a nutrient rich vermicompost using the earthworm Eudrilus eugeniae. The macronutrient and microbial analysis of vermicompost at various intervals of time has been studied and compared with decomposing water hyacinth. It was found that nitrogen, phosphorous, potassium and moisture were increased while organic carbon, C/N ratio, EC and pH were decreased. Microbial study revealed an increase in total count when compared with decomposed water hyacinth. The study of macronutrients is first of its kind in the water hyacinth vermicompost. The present work is a viable alternative for managing solid waste and pollution.
