Abstract

With porous structure, large surface area and rich oxygen-containing functional groups, biochar has been concerned widely as a soil conditioner for its potential use in soil improvement and remediation. In this paper, the characterizations of different biochar were firstly studied, then the application of biochar in improving soil fertility and repairing heavy metal pollution were summarized. Finally, future perspectives of biochar were also proposed. It was found that effects of biochar on soil improvement mainly included soil properties increasement, such as pH, cation exchange capacity (CEC) and nitrogen content, plant growth and crop yield enhancement, and microbial community improvement. In soil remediation of heavy metals pollution, biochar prepared from different raw materials could immobilize heavy metal ions by direct functions of electrostatic adsorption, ion exchange, complexation, precipitation, and indirect reactions with plant uptake and soil microorganism. Through this study, it can provide a reference for the application of biochar in soil improvement and pollution remediation, and give alternative method for resource utilization of solid wastes.
