What Is Rock Phosphate and How to Use It in Your Garden

· Rock phosphate also referred to as phosphate rock or phosphorite, is a type of nondetrital sedimentary rock packed with phosphate mineralization, including apatite In addition to being an essential organic source of phosphorus, phosphate rock also contains limestone, clay, and some other essential trace minerals Traditionally, gardeners used the rock, on its own, to add phosphorus to the

Should any of these countries choose to do so, they could dictate the world's food supplies That makes phosphorus a potential political weapon This 'situation' was considered so important that in 2014 the EU declared it a "critical raw material" This term

Use of phosphate rocks for sustainable agriculture

In the phosphate industry, the phosphate content of the rock is usually expressed as tricalcium phosphate and traditionally referred to as bone phosphate of lime (P 2 O 5 × 21853 = BPL) The latter term is reminiscent of the time when bones were the principal source of phosphate in the fertilizer industry Manufacturers of phosphoric acid and P fertilizers normally stipulate a minimum
