Abstract:
     The present invention refers to a process for the production of ammonium phosphate fertilizer by reacting ammonium bicarbonate with phospheric acid in reaction vessel and followed by vaporization and granulation. The high-efficiency compound N-P fertilizer contg. N greater than 10% and P2O5 greater than 46% is obtained by reacting low-efficiency single fertilizer, NH3HCO3, contg. N of 17% with medium or low concentration phosphoric acid (about 22%) by present process.
