Abstract: \nDuring the preparation of samples containing non-caking AN combined with serpentinite (SP), the mass ratio of AN to SP ranged from 100 : 0.5 to 100 : 2.5. The prilling method was employed to granulate the melt of serpentinite-nitrate. It has been demonstrated that the AN melt activates SP, facilitating the conversion of MgO from an indigestible form to a form that is readily absorbable by plants. In this scenario, serpentinite undergoes conversion, resulting in the formation of magnesium nitrate. The primary criterion for assessing the non-caking AN is the strength of the granules. If the strength of the granules for pure AN is measured at 1.32 MPa, then for fertilizers with the AN : SP ratio of 100: 0.5 and 100: 2.5, the corresponding strengths are 3.74 and 4.72, respectively. Based on the DTA studies carried out, we can conclude the following: an increase in the temperature of the modification transition IV→III and the reverse transition II→IV leads to the preservation of high strength and a decrease in the caking of AN granules during transportation and storage.\n
