Phosphoric Acid

Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H2PO4-, derived from phosphoric acid, H3PO4. The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid.

phosphoric acid produced is used to make fertilizers. It is mainly converted into three phosphate salts which are used as fertilizers. They are triple superphosphate (TSP), diamonium hydrogenphosphate (DAP) and monoammonium dihydrogenphosphate (MAP).

Phosphates are also used in a variety of other ways, including in soft drinks and as a supplement in feed given to cattle, pigs and poultry.
