Rock Phosphate Fertilizer
Rock phosphate is a mined rock that contains limestone and clay as well as a high concentration of phosphorus (P). The actual composition varies depending on it's source but it usually contains 16 to 20% P.

Phosphate Rock
While phosphate rock can be a valuable source of P for plants, it's not always appropriate for direct application. Its suitability depends partly on naturally occurring mineral impurities, such as clay, carbonate, iron and aluminum.

Rock Phosphate Fertilizer
Unless your soil pH is below 5.5, which is unlikely, the rock phosphate is completely insoluble. That means it does not mix with water, and it is not available to plants. One source I found suggests it starts to break down in 100 years.

Phosphate Fertilizer Plants
Phosphate fertilizers are produced by adding acid to ground or pulverized phosphate rock. If sulfuric acid is used, single or normal, phosphate (SSP) is produced, with a phosphorus content of 16–21% as phosphorous pentoxide (P 2 O 5). If phos-phoric acid is used to acidulate the phosphate rock, triple phosphate (TSP) is the result. TSP has
