Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43), loed 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 farmland. Animals absorb phosphates by eating plants or planteating animals.
