FIELD: mineral fertilizers.
SUBSTANCE: invention relates to ammonium nitrate-based fertilizer manufacture and consists in treatment of ammonium nitrate granules with solution containing chemical reagent and inert component, the former being potassium sulfate aqueous solution, with which prilled ammonium nitrate granules are treated at 40-50°C followed by treating granules with phosphogypsum (inert component) having moisture content 2-3% and grinding fineness no larger than 30 μm until its percentage in the granules attains 1-20%.
EFFECT: preserved high strength of ammonium nitrate granules at greater number of thermal cycles at temperatures 20 to 50C and increased temperature resistance.
