Vermicomposting offers an efficient biological method for transforming organic residues into valuable soil amendments through the activity of earthworms and associated microorganisms. This study investigates the changes in physico-chemical characteristics and enzyme activities during the vermicomposting of kitchen and agricultural wastes, along with their influence on soil fertility in the Kanpur region. Important parameters such as pH, electrical conductivity, organic carbon and essential nutrients (nitrogen, phosphorus, and potassium) were monitored throughout the process. Enzymatic activities, including dehydrogenase, urease, phosphatase, and catalase were also assessed to evaluate microbial functionality. The findings revealed a gradual decline in pH and C: N ratio, indicating stabilization of organic matter, while nutrient concentrations increased significantly in the final product. Enhanced enzyme activities suggested active microbial involvement in decomposition and nutrient transformation. Comparative results showed slight variations between waste types, though both produced high-quality vermicompost. Vermicompost improved soil nutrient status and biological activity, demonstrating its potential as a sustainable alternative to chemical fertilizer and environment conservation.
