Biochar and Soil Remediation

Biochar is the charred organic matter formed under high heat and low oxygen conditions that occur in natural fires and modern pyrolysis systems. Biochars have various properties for the remediation of polluted soils which include negative charge and large surface area. The use of biochar facilitates nutrient availability, enhance the microbial activity, soil organic matter availability, water holding and enhance crop production of soils. Biochar have excellent potential to adsorb the contaminants from soil solution and make them unavailable to organisms. Various methods come under biochar technique which includes carbon sequestration, nutrient exchange, water holding, adsorption/absorption and oxidation/reduction. Although this method (use of biochar in soil remediation) is simple, robust and suitable for many regions of the world but, its economic estimations and optimization should be taken into consideration for its large-scale implementation. Furthermore, various other public health related concern associated with biochar use should be addressed properly in order to establish biochar as a best alternative to other soil remediation methods, in future.
