Annotation

This article presents research data on systems involving urea, nitrate, sulfuric, and phosphoric acids using the polythermal method in the production of complex fertilizers. Polythermal solubility diagrams were constructed, and the obtained data were confirmed by results from electron microscopy and X-ray structural analysis methods
