How phosphate is mined and processed

Phosphorus in rock is pretty insoluble and thus not directly available to plants. In nature, rock phosphate can become soluble 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

Phosphate Rock an overview ScienceDirect Topics

Sometime colloidal rock phosphate is called soft rock phosphate, but it is no softer than regular rock phosphate. To be effective in crop nutrition, rock phosphate should be mixed well, not banded, in soil at pH 5.5 to facilitate its dissolution, and organic matter should be added to facilitate dissolution of the phosphate and to help keep it in solution. It may need to be applied
