Abstract

A procedure for the preparation of nitrophosphate fertilizers with different proportions of N/P2O5 in which a source of phosphorous comprising calcium is mixed with an acidic material capable of providing protons, said calcium is removed from the reaction mixture in the form of a salt, the resulting reaction mixture from which said calcium salt has been removed is treated with ammonia, and the ammonia-treated product is recovered, characterized by mixing a material containing bisulfate, selected from the group consisting of potassium bisulfate, bisulfate of ammonium and its mixtures with ammonium sulfate, with said phosphorous spring and with said acid material.
