摘      要：Biochar has gained significant attention in agricultural and environmental research over the last two *** comprehensive review evaluates the effects of biochar on soil organic carbon(SOC),emission of non-CO_(2) greenhouse gases,and crop yield,including related mechanisms and major influencing *** impacts of biochar on SOC,methane and nitrous oxide emissions,and crop yield are controlled by biochar and soil properties and management ***-temperature biochar produced from lignin-rich feedstocks may decrease methane and nitrous oxide emissions in acidic soils and strengthen long-term carbon sequestration due to its stable aromatic *** contrast,low-temperature biochar from manure may increase crop yield in low-fertility *** biochar to farmlands in China can increase SOC content by 1.9 Pg C and reduce methane and nitrous oxide emissions by 25 and 20 Mt CO_(2)-eq year^(−1),respectively,while increasing crop yields by 19%.Despite the increasing evidence of the positive effects of biochar,future research needs to explore the potential factors that could weaken or hinder its capacity to address climate change and secure crop *** conclude that biochar is not a universal solution for global cropland;however,targeted applications in fields,landscapes,or regional scales,especially in low fertility and sandy soils,could realize the benefits of biochar as a climate-smart measure.
