Assessment of nutrient status of vermicompost of leaf litter using Eisenia fetida

Abstract

The present study of 90 days was carried out to evaluate the nutrient status of vermicompost using Eisenia fetida. Three replicates of the substrate having cowdung+ leaf litter in ratio of 3:1 were maintained and the samples of substrate were collected on initial, 30th, 60th and 90th day of study for the analysis of carbon, nitrogen, potassium and phosphorus content. The reduction in organic carbon from 13.130% to 10.780% on 90th day while an increase in nitrogen, phosphorus and potassium content upto 17.90%, 44.73% and 18.24%, has been recorded respectively. C:N also marked significant decrease upto 32.60% that stamps the enhanced levels of nutrient due to earthworms’ activity.
