Potential Agronomic Benefits and Carbon Sequestration Ability of Biochar: Review

Abstract

Due to its aromatic structure, biochar is highly stable form of carbon in the soil that contributes to improve physicochemical and biological properties of soil and increased productivity due to the improvement of soil attributes and nutrient-use efficiency. Biochar can also play a great role to mitigate greenhouse gas emissions, like CO , N O and CH .This paper is briefly reviewed and synthesized recent findings and 2 2 4 discussions regarding the agronomic benefits of biochar and its effects on global climate change and particularly in relation to the agricultural environmental effect of biochar in soil. Therefore, suitable experimental trials combining biochar types and different pedoclimatic conditions are needed to determine the extent to which these reactions influence the potential of biochar as a soil amendment, crop responses for increasing yield and instrument for carbon sequestration.
