Vermicompost contains water-soluble nutrients which may be extracted as vermiwash and is an excellent, nutrient-rich organic fertilizer and soil conditioner. It is used in gardening and sustainable, organic farming. Vermicomposting can also be applied for treatment of sewage.

Vermicomposting is a process in which earthworms are used to convert organic materials into humus-like material known as vermicompost. A number of researchers throughout the world have found that the nutrient profile in vermicompost is generally higher than traditional compost.

Vermicomposting turns the green organic waste into dark, nutrient-rich soil, which, due to the presence of microorganisms, maintains healthy soil for growing healthy plants. Vermicomposting transforms the organic waste which is green in color, to a dark soil which enriches in nutrients.
