The article presents the results of research on the development of new types of phosphorus-containing fertilizers based on local raw materials. The resource-saving technology of obtaining concentrated superphosphate from high-carbonate raw materials of the Central Kyzyl Kum is shown. The main advantages of this technology are: the absence of units for diluting concentrated sulfuric acid, storage maturation of acidic superphosphate, ammonization, drying and granulation. The analysis of the obtained phosphorus fertilizers, obtained by the developed technology, showed that they are low hygroscopic, have a high moisture capacity, and their physical properties begin to deteriorate sharply only at a moisture content of about 20 %.
