The biological cycle of phosphorus differs from that of other bulk elements in so far that the complete cycle has a long half-life. The cycle is described and man's inputs are analysed. The immediate problems are the inputs to the environment of phosphate through fertilizers and detergents, but the long-term problem is the availability of workable sources of phosphate.
磷的生物循环与其他大量元素的生物循环不同，因为整个循环的半衰期很长。本文描述了该循环并分析了人类的输入。当前的问题是通过肥料和洗涤剂向环境中输入磷酸盐，但长期问题是可行的磷源的可用性。
