Ontop of high analysis phosphate fertilisers like TSP, MDCP has been used to treat contaminated land. MDCP is not produced directly by mixing DCP and MCP. The first reaction step is not mixing DCP and MCP in process pond to react, which some people think so. The production process of MDCP Polifar adopts is to
Phosphate treatment has emerged as a common approach to immobilise Lead (Pb) in contaminated soils and waste media, relying on the formation of the highly insoluble mineral pyromorphite as solubility-controlling phase for lead. Phosphate Treatment of Lead-Contaminated Soil can reduce Pb bio-availability in soils. Generally high analysis phosphate fertilisers created from phosphoric acid are used
