摘要： The over manipulation and incorrect use of soil and soil materials will continuously effect on attaining prerequisite food manufacture ranks and the biodiversity sustainability unless addressed properly. The soil pollution by inorganic substances is a main issue, predominantly regarding heavy metals and their lethal impact on agricultural production and quality of products, and health. Rapid industrial development has also fetched about hazardous contamination of soil by heavy metals in numerous republics. The soil contamination with heavy metal is of worldwide alarm as a consequence of its possible effects on the environment as well as on the human health. Generally Cu, As, Zn, Cr, Ni, Co, Sb, Th, Hg, Pb, Se, Cd and Si are all heavy metals that create in soil which tremendously damage human health and plant life by adulteration of water and soil. Heavy metals usually do not have the capability to biodegrade, hence they can persevere in contaminated soils for an extended period. Biochar can efficiently eliminate metal ions by the process of adsorption, electrostatic interaction, ion exchange, precipitation, complexation etc. The fast and easiness of production, reusability, eco-friendly nature, and economical are some of few benefits of biochar. It can be utilized as a soil stabilizer, or added to silage and fodder, or used in the treatment of water. Biochar can also be utilized for the pollutants immobilization from soil, and in the treatment of sewage. Biochar can also be utilized as a filter. Though, in this concern, biochar production and its application for soil mainly for management of waste, soil improvement, carbon sequestration and reduction in greenhouse gas emission from crop arenas has appeared as a remarkable field of research
