streszczenie
This paper presents laboratory investigations of grain size distribution, content change, as well as the change of static and dynamic angle of repose of mineral fertilizers Carbamide (CO(NH2)2), calcareous ammonium nitrate (NH4NO3 + CaCO3, 60:40), and ammonium nitrate (NH4NO3) depending on the hygroscopic influence of environment ie on the increased moisture of the fertilizers. Using charts, the functional dependence and the statistical data were analyzed. The conclusions are satisfactory, suggesting ways to overcome the discussed problem, and motivate further investigations in this field.
