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.

Phosphorus is not found uncombined in nature, but is widely found in compounds in minerals. An important source is phosphate rock, which contains the apatite minerals and is found in large quantities in the USA and elsewhere. There are fears that 'peak phosphorus' will occur around 2050, after which our sources will dwindle.

Phosphate: Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite varies greatly, from 4% to 20% phosphorus pentoxide. Marketed phosphate rock is enriched to at least 28%, often more than 30% P₂O₅.

Phosphate rock (phosphorite) is a marine sedimentary rock which contains 18-40% P 2 O 5, as well as some uranium and all its decay products, often 70 to 200 ppmU, and sometimes up to 800 ppm. The main mineral in the phosphate rock is apatite, and most commonly, fluorapatite – Ca 5 (PO 4) 3 F or Ca 10 (PO 4) 6 (F,OH) 2.
