Annotation
It was studied that it is possible to obtain complex phosphorus-sulfur and nitrogen-phosphorus-sulfur fertilizers with insecticidal properties necessary for agriculture by reprocessing low-grade Kyzylkum phosphorites in the presence of sulfur with incomplete standards of sulfuric and nitric acid. 30-40% of acid consumption is saved by replacing the amount of sulfur in the sulfuric acid used in the decomposition process with elemental sulfur. The received fertilizers contain phosphate minerals in mono- and dicalcium phosphate form, and sulfur in SO42- ion and elemental form. It was found that the sulfur in the fertilizer is in a completely hydrophilic form.
