Vermicomposting is a cost–effective and eco-friendly process used to treat organic waste. Vermicompost is nutrient rich organic compost with active microorganisms resulting from the interaction between earthworm and microorganisms on the breakdown of organic matter. Earthworms convert the waste material in to small particles by breaking in the gut of earth worm obtaining nutrients from the microbes that harbor on them. These processes increase the rate of degradation of the organic waste matter, modify the physico-chemical properties of the waste materials and forms humus in which unstable waste matter is completely oxidized. | Nội dung Text Study of vermicompost and vermiwash produced from cow manure and rice bran waste on the physiological growth of Abelmoschus esculentus L.
