PRELIMINARY OBSERVATION ON THE VERMICOMPOSTING OF VEGETABLE WASTES AMENDED WITH CATTLE MANURE

摘要

Vermicomposting of vegetable wastes amended with cattle manure using earthworm species Eisenia foetida was studied for a period of 45 days. The vegetable waste mixture had 45.15 +- 1.9% organic carbon, 1.5 +- 0.21% total nitrogen and 30.1 +- 2.1 C: Nratio initially. Organic carbon and C/N ratio decreased in both the control and experimental pots whereas nitrogen content increased during the study period. Significant variation in total organic carbon, nitrogen content and C/N ratio (P<0.05) was observed on 15th, 30th and 45th day of composting.
