Abstract:

China is confronted with severe challenges of desertification, sandy land expansion, and soil degradation, which urgently necessitate ecological restoration and soil conservation efforts. Biochar is a carbon-rich material derived from the pyrolysis of various feedstocks, which is commonly used as an amendment for soil improvement and remediation, and is of significant importance for improving sandy soils in arid regions. This study examines the effects of biochar on soil physical and chemical properties, carbon sequestration capacity,and crop growth in sandy soils. This review is conducive to understanding the current status of biochar application in sandy soils and enhancing the understanding and comprehension of the mechanisms underlying biochar-mediated soil improvement. It provides a reference for both practical applications and theoretical research on the use of biochar in sandy soils.

Key words: biochar, sand restoration, soil improvement, soil carbon sequestration, soil amendment
