Beschreibung
Zusammenfassung:	FIELD: production of granulated mineral fertilizers containing humate of alkaline metals; granulated phosphate fertilizers in particular, such as ammophos, diammonium and super-phosphate. ^ SUBSTANCE: proposed method includes preparation of granules containing ammophos, for example or diammonium or super-phosphate and humate of alkaline metal. Granulation is performed in drum-type apparatus by spraying pulp of phosphorus-containing fertilizer at moisture content of 8-15% onto recycled particles mixed preliminarily with loose humate of alkaline metal at size of particles not exceeding 0.15 mm. Humate is preliminarily mixed with recycled particles in separate reservoir or on conveyer feeding the recycled particles to granulation apparatus or directly in granulation apparatus. ^ EFFECT: improved agro-chemical properties of product. ^ 4 cl, 1 tbl, 1 ex
