Abstract

The production of NK and NMg fertilizers of various compositions from urea and finely crystalline potassium sulfate or urea and caustic magnesite powder was optimized. The commercial characteristics (qualitative composition, hygroscopicity, and strength) of the granulated NK and NMg fertilizers obtained were studied. The possibility of undesirable chemical reactions occurring on fusing potassium sulfate or magnesium oxide with urea in the fertilizer mixture was studied by X-ray phase analysis and IR spectroscopy.
