FIELD: agriculture, fertilizers. SUBSTANCE: invention relates to the field of production of liquid nitrogen-potassium fertilizers. Liquid nitrogen-potassium fertilizer has carbamide, potassium chloride, ammonium nitrate and water taken in the following ratio, wt.-%: carbamide, 20-34; potassium chloride, 5-25; ammonium nitrate, 25-42 and water, the balance. Except for, liquid nitrogen-potassium fertilizer has additionally 0.3-3 wt.-% of magnesium sulfate or 1.5-3 wt. -% of clay. Liquid nitrogen-potassium fertilizer has high content of potassium and nitrogen in amide, ammonium and nitrate forms in the total content of nutrient substances 32.64-32.9 wt.-%. Freezing point of fertilizer is -27.5-30 C. EFFECT: enhanced agrochemical properties of fertilizer. 3 cl
