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.

Rock phosphate, like greensand, can mineralize the soil and improve the quality of crops and soil structure. However, its principal uses are to build phosphate fertility where levels are low and/or to increase rooting activity in transplants and sprouting seeds. Phosphate Rock offers a small per cent age of its total phosphate content as immediately available.  Applications of Phosphate Rock can last 5 years or longer, depending on soil conditions.

Phosphate Rock is also often used in landscape and nursery applications to help plants adjust to the stress associated with transplanting.  Phosphates trigger root branching which gives the plant greater access to more of the nutrients it needs. OMRI Certified
