Abstract

See full text

The efficiency of applied phosphorus can be improved by applying phosphorus as a coating onto plant growth (roots and shoots) or by applying phosphorus as a coating on prills or granules of other forms of fertilizers. The composition comprises (a) monoammonium phosphate, (b) struvite and (c) magnesium sulphate. The first two ingredients ensure that there is a source of rapidly available phosphorus (MAP) and a source of more slowly available phosphorus (STRUV). The third ingredient is to provide a source of sulphate which will, in the area surrounding the coated product following application thereof to the soil, act to stop ambient calcium from reacting with the phosphate thereby rendering it inactive.
