Efficient Recycling of Crop Residue through biochar for better agriculture and environment

Abstract

Biochar is a solid material obtained from the carbonisation of
biomass. Large varieties of biomass products can be used to produce biochar. It improves fertility and quality of poor soils, thus, reducing the need for fertilizer inputs and enhancing crop productivity, by transforming low value crop residue into potentially high value carbon source. Application of biochar has several environmental benefits including mitigation of greenhouse gas emission and long term carbon storage in soil. So, biochar can be an important tool to increase food security and cropland diversity in
areas with severely depleted soils, scarce organic resources, and
inadequate water and chemical fertilizer supplies in a sustainable way.
