Rock Phosphate

Rock phosphate is a naturally mined product rich in phosphorous, calcium, and carbon as well as many trace minerals. It supplies crops with a form of P that is much more stable in the soil profile and feeds soil biology which ultimately makes more phosphorous available to growing plants.

Application rates: 200-500 lb./acre and up to 1 ton per acre depending upon crop and soil.
