Rock phosphate

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rockwhich contains high amounts of phosphate bearing minerals. Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize. In the past, rock phosphate was used alone as a fertilizer, but due to a lack in supply, as well as low concentration, most applied fertilizer is processed. We supply in bulk quantity.
