Phosphate Rock is a natural, untreated soft phosphate with colloidal clay containing valuable minor minerals in OMRI listed rgbaddition to phosphorus. It is not acid forming, will not cake or harden and spreads easily through any type of lime, phosphate or fertilizer spreader.

{tab Details}
Phosphate Rock is not a complete fertilizer and should never be used as such, however, this is an excellent source of phosphate that can be used profitably on certified organic farms. When applied to the soil, Phosphate Rock adheres to and becomes a part of the soil. It will not leach and once applied, remains in the soil until used by the plants. Phosphate Rock contains no harmful acids and encourages growth of soil bacteria and earthworms. Natural rock phosphates are from deposits of apatite rock formed eons ago by sea life that left behind fossils and shells composed primarily of calcium phosphates. Over millions of years, the remains accumulated and were subjected to millions of tons of pressure; creating sedimentary rock deposits. One of the richest deposits of apatite rock in the world was discovered in the Southern United States. Most of the phosphates used in modern agriculture, science, and industry are refined from apatite rock.
