Vermi Composting

Vermicomposting is basically a managed process of worms digesting organic
matter to transform the material into a beneficial soil amendment. As per the
USDA guidelines for compost practices (with effect from Oct 21, 2002),
vermicomposts are defined as organic matter of plant and/or animal origin
consisting mainly of finely-divided earthworm castings, produced nonthermophilically with biooxidation and stabilization of the organic material, due to
interactions between aerobic microorganism and earthworms, as the materials
pass through the earthworm gut.
