Abstract
This review primarily focuses on the advancement of biochar research methods and their application in treating soil pollution and agriculture. Biochar, a novel material for soil treatment, shows great potential because of its high specific surface area, abundant functional groups, and well-developed pore structure. This work first introduces the current state and hazards of soil pollution and the limitations of traditional remediation technologies. It then discusses biochar research methods and advancements in biochar preparation techniques. This paper also discussed the application of biochar in the agricultural field. Although biochar has shown many advantages in soil remediation, technical and economic issues in its production remain to be resolved, and long-term environmental impacts and ecological safety need to be further evaluated. Future research should focus on the functional modification and application optimization of biochar to fully realize its potential in soil remediation and sustainable agricultural development.
