GRANULAR SULFUR-CONTAINING NITROGEN-POTASSIUM FERTILIZER AND METHOD FOR ITS PRODUCTION Russian patent published in 2021 - IPC C05G1/00 C05G5/12 C05D1/02 C05C3/00 C05C5/02 

Abstract RU 2747779 C1

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.
