Disposal of enormous amounts of wastes generated from various sources is becoming a serious problem in our country. Vermicomposting is an economically viable technology in conversion of wastes into a high quality manure which is a valuable input in organic agriculture. Hence an experiment was carried out to study the changes occurring during vermicomposting of different bio-degradable wastes for assessing the stability & maturity of vermicompost. Four different bio-degradable  wastes i.e., Vegetable market waste, Agricultural waste, Kitchen waste and Paddy straw were composted separately using earthworms. Irrespective of wastes, C/N ratio (Ratio of Carbon to Nitrogen) decreased significantly during the process of vermicomposting. Humic acid (HA) production was increased while production of fulvic acid (FA) was decreased during vermicomposting of bio-degradable  wastes. It was observed during different time intervals that humic acid levels were high when compared to fulvic acid. Among the different wastes under study, higher and lower values of humic and fulvic acids were recorded in vermicompost prepared out of agricultural waste and paddy straw respectively.


Key words: Vermicompost, Bio-degradable wastes,  C/N ratio, Humic acid, Fulvic acid, HA/FA ratio.
