The researchers used earthworms to turn Phumdi from Loktak Lake into organic fertilizer through vermicomposting. They mixed Phumdi with cow dung slurry, pre-composted it, and then harvested the vermicompost after 60 days. The earthworms' growth improved during the experiment, and the compost and vermicompost had higher levels of primary nutrients. However, the trace elements decreased. The optimal temperature for worm activity was 23-24℃, with a moisture content of 57-61%. The C/N ratio decreased over time, with final ratios of 14.09 for compost and 11.22-10.41 for vermicompost. Vermicomposting Phumdi produces nutrient-rich fertilizer and helps clean up excess Phumdi around the lake.
