Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO4³⁻), located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on ...

Phosphates move quickly through plants and animals; however, the processes that move them through the soil or ocean are very slow, making the phosphorus cycle overall one of the slowest biogeochemical cycles. Initially, phosphate weathers from rocks and minerals, the most common mineral being apatite.

Humans affect the phosphorus cycle mainly by the use of fertilizers and raising livestock, especially hogs. Fertilizers and hog waste are high in phosphorus, which makes its way into the soil (where it is necessary in moderate amounts) and, due to runoff, in water.
