TOP PHOS is a new and unique type of complex super phosphate (CSP). TOP PHOS is a monocalcium phosphate protected against lock up in high and low pH soils and is fully soluble in water.
TOP-PHOS is a new and unique chemical form of phosphorus compared to standard P fertilisers. It has been recognised within the EU REACH regulations as being different to the traditional forms of P used in standard fertilisers. TOP PHOS is a molecule that complexes phosphate in an organic-matrix through a calcium bridge and is immediately available for plant uptake throughout the growing season. Phosphate availability is combined with a root system stimulator and a biological activity booster.
