Current agriculture faces multiple challenges due to rapid increases in food demand and environmental concerns. Recently, biochar application in agricultural soils has attracted a good deal of attention. According to literature findings, biochar has proven to play various beneficial roles with respect to the enhancement of crop yield as a fertilizer and soil quality as a soil conditioner. It can further be used to remediate soil pollution as an adsorbent, while supporting the mitigation of greenhouse gases (GHGs) through the expansion of the soil carbon pool. The efficacy of biochar application on agricultural environments is found to be controlled by various factors such as pyrolysis temperature, feed stock, soil type, and biotic interactions. The combined effects of these factors may thus exert a decisive control on the overall outcome. Furthermore, the biochar application can also be proven to be detrimental in some scenarios. This review evaluates both the potential benefits and limitations of biochar application in agriculture soils.
当前，由于粮食需求的快速增长和环境问题的出现，农业面临着诸多挑战。最近，生物炭在农业土壤中的应用引起了广泛关注。根据文献研究，生物炭已被证明在提高作物产量方面具有多种有益作用，它可以作为肥料来改善土壤质量，也可以作为土壤调节剂。此外，它还可以作为吸附剂来修复土壤污染，并通过扩大土壤碳库来支持温室气体（GHGs）的减排。生物炭在农业环境中的应用效果受到多种因素的控制，如热解温度、原料、土壤类型和生物相互作用等。因此，这些因素的综合影响可能对整体结果产生决定性的控制。此外，生物炭的应用在某些情况下也可能有害。本综述评估了生物炭在农业土壤中的应用的潜在益处和局限性。
