The phosphorus cycle — Science Learning Hub

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 farmland. Animals absorb phosphates by eating plants or plant-eating animals.

Rock Phospate vs. Superphosphate - Houzz

Rock phosphate and colloidal phosphate are both pulverized forms of the mineral apatite, generally by-products of a mining process, and slow-release forms of phosphorous. "Colloidal" simply refers to the particle size. Superphosphate is apatite that has been reacted with an acid, thereby changing the chemistry and concentrating the phosphorous.

How phosphate is mined and processed

rock phosphate can become soluble (and available to plants) either by chemical weathering or through the actions of certain types of plants. The solubility also depends on rock type and the pH of the soil; phosphorus is most soluble when contained in sedimentary rocks as opposed to igneous rock, and when soil pH is between 5.5 and 7.2.
