Vermicast (also called worm castings, worm humus or worm manure) is the end-product of the breakdown of organic matter by an earthworm.[1] these castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than do organic materials before vermicomposting. At chackra we make 100% organice vermicomposting using indian indigeneous cow dung and other organic waste.
