The solubility of components in the Ca(NO3)2-Mg(NO3)2-H2O system was studied in a wide range of temperatures and concentrations using the visual-polythermal method. Based on the data obtained, a polythermal solubility diagram of the system was constructed, on which the crystallization fields of ice, four, three and two aqueous calcium nitrate, and nine and six aqueous magnesium nitrate are delimited. System of simple euthenic type. Analysis of the solubility diagram of the Ca(NO3)2-Mg(NO3)2-H2O system shows that due to its good solubility, calcium nitrate has a significant salting-out effect on magnesium nitrate, which increases with increasing temperature and concentration of the system components. Also, to develop technological solutions for the production of fertilizers, the physicochemical properties of the system solutions were studied and a “composition-property” diagram of the system was constructed depending on the composition of the components.
