The process by which earthworm convert organic manure in to fertile manure is called Vermi-composting. Important species of earthworm used for vermicomposting in Indian conditions are Epigeic Eugeniae, Eisenia Foetida, and Perionyx Excavatus. Vermi-compost are used in farming and small scale sustainable organic farming because they contains water-soluble nutrients and is an excellent, nutrient-rich organic fertilizer and soil conditioner. Earthworms grind and uniformly mix minerals in simple forms, which makes it easy for the plants to obtain them. The end-product of the breakdown of organic matter by earthworms is called vermicast. These castings contains reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting. Hence, Worm castings can be used as an organic fertilizer.
