COMPACTED POTASSIUM FERTILIZER CONTAINING MICRONUTRIENTS, AND METHODS OF THEIR PRODUCTION Russian patent published in 2017 - IPC C05D1/02 

FIELD: agriculture.

SUBSTANCE: invention relates to inclusion of micronutrients in fertilizers based on potassium chloride using methods of packing. Combined product based on potassium chloride (MOP product), obtained from compacted MOP composition, where composition contains: potassium chloride with potassium content from approximately 48.0 wt% to approximately 62.0 wt% in terms of K₂O; and source of boron in amount, at which content of boron in MOP product is from 0.001 to 1.0 wt%. Method of producing combined MOP product, containing micronutrients, involves obtaining MOP composition, containing potassium chloride with potassium content from approximately 48.0 wt% to approximately 62.0 wt% in terms of K₂O, and source of boron in amount, at which content of boron in MOP product is from 0.001 to 1.0 wt%: packing of MOP composition to produce compacted MOP composition; milling of MOP composition to form granules to obtain combined MOP product.

EFFECT: invention enables to obtain cheap, compacted, crushed and sorted by size granular MOP fertilizer with additional useful properties, which maximize introduction of micronutrients in soil solution and ultimate delivery into root zone of plants.
