Abstract
This article presents the results of research on the production of complex fertilizers based on the neutralization of samples of Central Kyzylkum waste phosphorite in ammonia solution of the decomposed product at incomplete levels of nitric acid. This includes the study of complex mineral fertilizers containing PN by decomposing phosphorite samples at different rates (40-90) and neutralizing the resulting slurry with ammonia solution in the atmosphere of pH with the range 5.5-8.5. All forms of P2O5 and CaO (total, plant- soluble and water-soluble) and total nitrogen content, which were the main constituents of the samples obtained, were analyzed.
