Apatite is acidulated with HCl towards the stoichiometric amount required for producing dicalcium phosphate. The reaction product when mixed with ammonium sulphate sufficient to doubledecompose calcium chloride and dicalcium phosphate yields a nonhygroscopic product made up of Just about all phosphorus within the water-soluble form.Hydroponic incre
