The intervention of human in phosphorus pool seems to be a vicious circle. The rapid population growth leads to the global food shortage, which leads to the massive use of phosphate fertilizer and the continuous exploitation of phosphate rocks. With the massive loss and fixation of phosphate fertilizer in the soil, the unavailable phosphorus in the soil becomes superfluous, while the phosphate mineral resources turn to scarce. Interestingly, exogenous carbonaceous materials, notably, biochar and humic substances, have been widely used as soil conditioners in agricultural production up to date, among other actions to interfere with the balance between the different phosphate species, which offer effective roles for increasing soil available phosphorus. This article reviews the regulation mechanisms of biochar and humic substances on phosphorus availability and circulation, including improving soil physicochemical characteristics, regulating microbial community structure, and directly interacting with phosphorus to affect the fate of phosphorus in soil. Finally, the prospects for future research directions are made, and it is hoped that the review of this article can arouse people's attention to the current plight of agricultural production and provide some methods for improving the efficiency of phosphate fertilizer use in the future.

人类对磷池的干预似乎是一个恶性循环。人口的快速增长导致全球粮食短缺，导致大量使用磷肥和对磷矿的不断开采。随着土壤中磷肥的大量流失和固着，土壤中无法利用的磷变得多余，而磷酸盐矿产资源却变得稀缺。有趣的是，迄今为止，外源碳质材料，尤其是生物炭和腐殖质，已被广泛用作农业生产中的土壤改良剂，其中包括干扰不同磷酸盐种类之间平衡的其他作用，这些作用为增加土壤有效磷提供了有效的作用。 。本文综述了生物炭和腐殖质对磷的有效性和循环的调节机制，包括改善土壤理化特性，调节微生物群落结构以及与磷直接相互作用以影响土壤中磷的命运。最后，展望了未来的研究方向，希望本文的综述能够引起人们对当前农业生产困境的关注，并为今后提高磷肥的使用效率提供一些方法。
