NITROGEN-POTASSIUM FERTILIZER AND METHOD FOR MANUFACTURE THEREOF

摘要

FIELD: mineral fertilizers. SUBSTANCE: fertilizer containing 12-43% (on conversion to N) of urea and 3-40% (on conversion to K2O) of potassium sulfate-potassium chloride mixture is prepared by mixing urea solution with potassium sulfatepotassium chloride mixture, granulating resulting blend on drum granulator at 100-140 C and temperature fall gradient over the drum length 1.9-3.9 C/m. EFFECT: improved physicochemical and agrochemical properties and extended range of suitable crops. 3 cl, 7 ex
