Vermicompostng as Advocacy for Climate Change Due to Crop Production - A Review

Abstract

In sub- Saharan Africa including Ethiopia, vermicompost is painstaking a valuable or organic fertilizer in many tropical areas, but has hardly been used. Organic litters after completion of decomposition returned to the soil can preserve, improves eminence, fertility and productivity through promising effect on soil physical, chemical and biological characteristics and other processes. Vermicomposting technology for composting of organic wastes is unusually effective for reduction in the processing time of decomposition and produce good quality compost in terms of nutritional contents. Vermicomposting serves as a significant factor of integrated plant nutrient supply system for balanced fertilization along with maintaining health to sustain the productivity of soils. Organic wastes returned to soil as vermicompost contribute to reduce the fertilizer requirement of the crop. Vermicomposting increase crop yield by many fold, these increased yield directly helps in minimization of cultivable land for the objective of crop production, so this can directly help for ecological conservation.  More beneficial effects vermicomposting on yield and quality of crop are also highlighted in the review.
