FIELD: fertilizers.
SUBSTANCE: invention relates to fertilizers including nitrogen-containing component and potassium-containing component. As nitrogen-containing component fertilizer includes mixture of ammonium nitrate and ammonium sulfate, and as potassium-containing component it includes mixture of potassium sulfate and potassium chloride in amount of (mass %): mixture of ammonium nitrate and sulfate 10-27 (as calculated to N), mixture of potassium sulfate and chloride 3-40 (as calculated to K2O). Chlorine ions content is up to 0.25. Method for fertilizer production includes component blending to produce slurry which is additionally neutralized with ammonia at 130-160°C. Granulation is carried out at 120-160°C.
EFFECT: explosion-proof process; increased content of ammonia nitrogen; reduced chloride content.
