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.
Bone meal and rock phosphate are typical sources. If you can find them, fish bone meal and soy husks are other good sources. And then there is compost :-) Composted yard waste and manures generally provide all the phosphorus normally required by most plants in most soils and if applied in excess, can create an oversupply.

Phosphorus (P) is a macronutrient required for the proper functioning of plants. Because P plays a vital role in every aspect of plant growth and development, deficiencies can reduce plant growth and development. Though soil possesses total P in the form of organic and inorganic compounds, most of them remain inactive and thus unavailable to plants. Since many farmers cannot afford …

In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the world's third-largest producer, after China and Morocco. The phosphate mining industry employed 2,200 people. The value of phosphate rock mined was US$2.2 billion. As of 2015, there are 10 active phosphate …
As part of the valorization of the Moroccan phosphate rock by extraction of rare earths, different experiments on natural Moroccan phosphate from the Gantour Basin (basin of phosphate in the Youssoufia area) were done in the REMATOP laboratory. The response surface methodology was used to study the effects of the influence of different parameters …
Phosphorus is a component of DNA, RNA, ATP, and also the phospholipids that form all cell membranes. It is not found in its free element form on Earth due to its high reactivity. Phosphorus as a mineral is present in oxidized state, as inorganic phosphate rocks. Phosphate rock is used as a phosphatic fertilizer after grinding called phosphorite or mineral phosphate.
