Role of Vermitechnology for Enhancing Crop Productivity and Mitigation of Global Warming

Fasil Shimelis Gebreyohannis* and Abrha Gebregiyorgis

The global scientific community today is searching for a technology which should be economically viable, environmentally sustainable and socially acceptable. Vermicomposting is a low-technology, environmentally-friendly process used to treat organic waste. Yet its role in the nutrition of agricultural fields has attracted attention of researchers worldwide. 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 is a nutritive organic fertilizer rich in humus, micronutrients, beneficial soil microbes; nitrogen-fixing, phosphate solubilizing bacteria, and growth hormones auxins, gibberellins and cytokines. Both vermicompost and its body liquid (vermiwash) are proven as both growth promoters and protectors for crop plants. Therefore the objective of this review paper is scientifically prove that vermin-technology with the aid of enhancing crop productivity and mitigation of global warming.
