METHOD OF OBTAINING OF GRANULATED NITROGEN-POTASSIUM FERTILIZING Russian patent published in 2014 - IPC C05C1/02

Abstract RU 2535167 C1

FIELD: agriculture.

SUBSTANCE: method of obtaining of granulated nitrogen-potassium fertilizing includes the mixing of the concentrated solution of ammonium nitrate with potassium chloride and ammonia, granulation of mixture and drying of the product, and during granulation on the obtained dispersible product the water solution of magnesium sulfate with 24-30 - percent mass concentration is applied in the amount ensuring the content of magnesium sulfate in a ready product in terms of MgO no less than 0.5 by mass.

EFFECT: invention allows to increase the strength of fertilizing granules and to decrease its caking at a long storage.
