Abstract
Higher global warming and irregular climatic patterns significantly impacted ecosystems, mainly due to the increase in greenhouse gases from agriculture. Methane has emerged as a primary contributor among gases, hence the need to curb CH4 in combating global warming. Among the best mitigative options, the use of biochar, produced by charring crop residues at high temperature in reduced oxygen, emerges. The stable, high-carbon material sequesters soil carbon in addition to minimizing emission of CH4 and N2O. When applied to soil, biochar enhances crop productivity, improve resource use efficiency through sustainable conversion of crop residues. Its porous texture stimulates soil microbes, soil health and sustains long term fertility. Due to its permanence, the use of biochar constitutes an effective carbon capture and sequester instrument. When applied in broader sustainable applications, the material contributes significantly to climatic change mitigation in addition to the establishment of long-term resilient crops.
