Abstract: The process of obtaining NK and NMg-fertilizers of various compositions from carbamide and fine-crystalline potassium sulfate or carbamide and caustic magnesite powder has been optimized. The commodity properties (qualitative composition, absorbability, strength) of the obtained granulated NK and NMg fertilizers have been studied. By the methods of X-ray phase analysis and IR spectroscopy, the possibility of undesirable chemical reactions during the fusion of potassium sulfate or magnesium oxide with carbamide in fertilizer mixture melt has been investigated.
Key words: prilled carbamide, complex fertilizers, consumer qualities, carbamide melt, fine-crystalline products.
