This paper presents the results of studies on the study of the chemical composition of ammophosphate obtained on the basis of phosphoric acid processing of off-balance phosphorite ore of the Central Kyzyl Kum. The effect of the mass ratio of phosphate raw material and extraction phosphoric acid on the content of nitrogen in the finished product, as well as the general and assimilable forms of P2O5, has been established. The results obtained indicate the possibility of using technogenic waste - off-balance ore as an alternative source of phosphorus-containing raw materials, and the resulting fertilizers on their basis fully satisfy the requirements of agriculture.
