The phosphorus cycle — Science Learning Hub

Here are the key steps of the phosphorus cycle. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil. The plants may then be consumed by animals. Once in the plant or animal, the phosphate is incorporated into organic molecules such as DNA. When the plant or animal dies, it decays, and the organic phosphate …

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.

01/01/1993· The main steps of the acidulation process as proposed by Becker are: 1) Ionization of H 2 SO 4 (3) H 2 SO 4 → 2 H + +SO 4 − 2 this is a very fast reaction. ii) Attack of the H + ion on the phosphate rock particles.

Phosphate - Wikipedia

Some phosphate rock deposits, such as Mulberry in Florida, are notable for their inclusion of significant quantities of radioactive uranium isotopes. This syndrome is noteworthy because radioactivity can be released into surface waters [14] in the process of application of the resultant phosphate fertilizer (e.g. in many tobacco farming operations in the southeast US).
