In majority of India, reduced soil fertility has led to declining crop yields on many small-scale farms causing food insecurity and greater poverty. Soil fertility can be increased by use of chemical fertilizers but these are too expensive for many farmers and are not always available. Increasing the decomposition of organic wastes by enrichment of chemical and biological amendments are some of the modern developments in composting technology. Traditional organic manures are mostly deficient of essential macro and micronutrients as well as beneficial microbial population. The chemical enrichment accelerates the breakdown of organics into the soluble and mineralized nutrient forms.
