Zusammenfassung:	agriculture. SUBSTANCE: method comprises mixing ammonium nitrate fusion cake with potassium chloride which is added in amount of 5.00-36.35 wt %, granulation of the resulting melt by drilling melt drops in granulating mill. Melt drops result from separating melt jets flowing out of granulating mill and air current, ratio of dynamic pressure of melt jet to hydrostatic pressure in granulating mil is chosen within 1.3-5.3. Besides, ratio of specific weight flow rates of melt jet and air current is maintained within (4,5-17,3)x103. Nitrogen-potash fertilizer comprises, wt %: N, 21.43/32.3; and K2O, 3.00-22.17. EFFECT: unchanged efficiency and improved parameters of the resulting fertilizer. 5 cl, 5 ex, 2 tbl
