PHOSUL will provide a composition and method for supplying phosphate fertilizer to plants while generating it in a way that avoids pollution， and most efficiently utilizes earth's finite phosphorus resources. PHOSUL is plant-available phosphate fertilizer. In the soil， phosphate in rock phosphate is biologically transformed into plant-available phosphate and gypsum. PHOSUL provides a natural process to make continuous release phosphate fertilizer. The PHOSUL granules should be incorporated in the soil at seeding or surface spread， as granules， or in blends， to provide vital phosphate for plant growth.
