ABSTRACT:
The present invention relates to a process for the direct manufacture of crystalline urea phosphate. The process consists in the reaction of solid urea with ortho-phosphoric acid in a substantially anhydrous form. A concentrated phosphoric acid with above 90% by weight H.sub.3 PO.sub.4 can be used as starting reagent. A preheating of the phosphoric acid at 60.degree.-90.degree.C is preferred in order to induce the spontaneous reaction with the solid urea. The urea phosphate product obtained is ready for use without any further operation. Desired micronutrients such as Mg, Co, Fe, Zn, Cu, Mn may be incorporated in the initial ortho-phosphoric acid prior to the reaction with the solid urea.
