This article is devoted to the use of ammonium sulfate in the production of nitrogen-phosphorus fertilizers, which are widely used in agriculture today. In the research work, the possibilities of obtaining azo superphosphate are described in detail by the use of intensive technology based on low-grade phospharites of the Central KyzylKum. X-ray and IRspectroscopic analyzes of a new type of NP-complex fertilizers obtained using a solution of ammonium sulfate in sulfuric acid are described in detail. The X-ray analysis of the obtained sample on the X-ray diffraction pattern of the azo-superphosphate fertilizer revealed the appearance of peaks in the interplanar spacing line (NH4)2SO4 of ammonium sulfate and NH4Н2РO4 of ammonium dihydrogen phosphate. It has been substantiated that in addition to the main nutrient components dicalcium phosphate and monocalcium phosphates, the sample also contains (NH4)2SO4 and NH4Н2РO4. The results of IR spectroscopic analyzes show that the process of decomposition of the CO3 2-ion in the composition of phosphorites, peaks with high intensity formed by stretching vibrations, in the regions of 873.75 and 1417.68 cm-1, were not detected in the IR spectra of the obtained sample and this proves that that the complete decomposition process is complete. Also, the formation of stretching vibrations of the H2PO4-ion - 1215.15 cm-1, the PO4 3-ion - 532.35 cm-1 and bending vibrations of the H2PO4 -ion - 1033.85 cm-1 in the IR spectrum of the sample in this NH4Н2РO4 sample and the formation of stretching vibrations of SO4 2-ion 1436.97 cm-1 confirmed the presence of (NH4)2SO4.
