ESTIMATION OF PHYSICO-CHEMICAL PROPERTIES OF VERMIWASH OF DIFFERENT COMBINATIONS OF MSW WITH ANIMAL DUNG THROUGH VERMICOMPOSTING BY EARTHWORM EISENIA FETIDA

Harendra Kumar Chauhan , Keshav Singh

The municipal solid wastes (MSW) caused environmental hazards and various ill effects on human life and their domestic animals. Managment of MSW through vermicomposting by the help of epigeic earthworm Eisenia fetida had an appropriate alternative technology for recycling and production of organic fertilizers. The significant decrease in pH, C/N ratio and organic carbon whereas, significant increase in the level of potassium, phosphorus and calcium in different combinations of vermiwash of MSW with animal dung with respect to the initial feed mixture were observed. The organic carbon was significantly decreased 67.42 % MG25 (MSW with goat dung in ratio of 75:25). The pH of initial mixture in all combinations was tending to acidic/neutral nature. The nitrogen content in vermiwash was significantly increased 68.02% in MG50 (MSW with goat dung in ratio of 50:50) where as maximum organic nitrogen observed 28.31 in MG25 (MSW to goat dung ratio 75:25). The C/N ratio in all vermiwash was ranged 6.80 to 25.30 and significantly decreased in initial feed mixture. Data obtained from present study is helpful to prepare the specific type of combination of vermiwash for particular nutrients. The aim of present study was to investigate the production and characteristics of vermiwash of MSW with different animal dung by earthworm Eisenia fetida
