Abstract: Vermicompost (also called worm compost, vermicast, worm castings, worm humus or worm manure) is the base-product of the breakdown of natural material by earthworms. Vermicompost is a nutrient-rich, organic fertilizer, and soil conditioner. The process of making vermicompost is called vermicomposting. It contains not only worm castings, but also bedding materials and organic wastes at a mixture of stages of decomposition. It also contains worms at different stages of growth and other microorganisms associated with the process. Earthworms’ castings in the home garden usually contain 5 to 10 times more additional nitrogen, phosphorous, and potassium than the adjacent soil. Secretions in the intestinal tracts of the worms, along with soil passing through the worms, make the nutrients needed by plants more concentrated and available for plant uptake.
