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.

About 15% of phosphate reserves are found in volcanic (extrusive) igneous rocks. These reserves are found in Russia, Finland, South Africa, and Brazil. Most phosphate reserves are from sedimentary rocks. The phosphate-rich sedimentary rock forms in the shallow oceans mainly due to bacterial activity, but only when several conditions are met.
