FIELD: agriculture.
SUBSTANCE: granular sulfur-containing nitrogen-potassium fertilizer includes a nitrogen-containing component and potassium sulfate, while additionally contains potassium nitrate at a mass ratio of potassium sulfate and potassium nitrate of 1: (1.1 - 1.2), and the nitrogen-containing component is ammonium sulfate nitrate of the composition (NH4)2SO4⋅2NH4NO3 with its content in the fertilizer of 60-70 wt%. A method for producing sulfur-containing nitrogen-potassium fertilizer is proposed.
EFFECT: inventions make it possible to obtain a granular sulfur-containing nitrogen-potassium fertilizer with an optimal ratio of the main nutrients (NK) and an optimal ratio of sulfur to these elements, while increasing the physical and mechanical properties of the granules.
