    Soft Rock Phosphate (SRP) products are an excellent natural source of phosphorus calcium and many essential trace elements including silica. The rock phosphate product is pre digested making it more soluble than other sources of phosphate rock and this form of P is readily available does not lock up to other cations such as calcium.

    Like hard rock phosphate it may only be listed as 3% available but over a few years its 100% available to plants. It does combine with calcium but not in the unbreakable bond that hard rock creates. Its also a good source of silicon and many trace minerals. In addition to the colloidal type theres reactive soft rock phosphate.
