We studied vermicomposting with Eisenia foetida of mixed garden litter with cow dung in 3: 1 ratio, in a 180 day composting experiment. The change in chemical characteristics of mixed substance measured at 45 days intervals. The Vermicomposting resulted in significant reduction in pH (9.4 to 7.8), total organic carbon (9.84 to 8.38%), and C: N ratio (46 to 27) and increase in total Kjeldahl nitrogen (0.21 to 0.302%), ammonical nitrogen (8.78 to 16.0 mg/kg), nitrate nitrogen (85.89 to 9.2 mg/kg), available phosphate (4.34 to 7.6 mg/kg) and total potassium (6.14 to 8.9 mg/kg) after 180 days of composting. The study revealed that vermicomposting might be an efficient technology to convert negligible organic solid waste to value added product.
