Phosphate Rock is an excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30 percent total phosphate (3-8 percent available) and 48 percent calcium (as CaO). Phosphate rock has approximately one fifth the neutralizing power of lime. Natural rock phosphates are from deposits of apatite rock formed ...

Florida's phosphate rock deposits are believed to have originated in several ways. Some of the phosphate may have formed when conditions in the seawater caused dissolved phosphorus to solidify, a process scientists call precipitation. As material settled to the bottom of the shallow coastal waters, it became part of the sedimentary layers ...
