Nutrient recycling through vermicomposting can enhance plant nutrient content. Earthworms Eudrilus eugeniae and Perionyx excavatus were studied for vermicomposting rice straw. P. excavatus produced vermicompost with higher N, P, K, and Mg levels, while E. eugeniae had more Ca and humic acid. Despite lower nutrient levels in initial plant residues, vermicomposting rice straw resulted in the highest nutrient content. Enzyme and microbial activity in vermicompost remained active even after 6 months of storage, suggesting continued nutrient cycling benefits for agricultural land.
