Earthworm cast is the earthworm waste. From
the component terms,it contains organic matter, humic acid, nitrogen,
phosphorus and potassium. It has been
shown to contain reduced levels of contaminants and a higher saturation of
nutrients than do organic materials before vermicomposting. A research from scientificresearch publishing has state the worms composting technology, its importance,
use and some salient results obtained in the globe so far,I think it may advance
the course of vermicompost:
Earthworm has caught imagination of
philosophers like Pascal and Thoreau. Yet its role in the nutrition of
agricultural fields has attracted attention of researchers worldwide only in
recent decades. Waste management is considered as an integral part of a
sustainable society, thereby necessitating diversion of biodegradable fractions
of the societal waste from landfill into alternative management processes such
as vermicomposting. Earthworms excreta (vermicast) is a nutritive organic
fertilizer rich in humus, NPK, micronutrients, beneficial soil microbes;
nitrogen-fixing, phosphate solubilizing bacteria, actinomycets and growth
hormones auxins, gibberlins & cytokinins. Both vermicompost & its body
liquid (vermiwash) are proven as both growth promoters & protectors for
crop plants. We discuss about the worms composting technology, its importance,
use and some salient results obtained in the globe so far in this review update
of vermicompost research.
