СПОСОБ ПОЛУЧЕНИЯ КОМПЛЕКСНОГО УДОБРЕНИЯ путем разложения минерального сырья, содержащего сульфат калия, фосфорной кислотой, с последующим отделением гипса, обработкой раствора аммиаком и сушкой продукта, отличающийся тем, чта, с целью повышения степени использования минерального сырья и уравновешивания содержания питательных веществ в продукте разложение фосфорной кислотой ведут в присутствии нитрата кальция, который берут в количестве, обеспечивающем связывание содержащихся в минеральном сырье сульфатионов в гипс. 'METHOD FOR PRODUCING INTEGRATED FERTILIZER by decomposing mineral raw materials containing potassium sulfate, phosphoric acid, followed by separation of gypsum, treating the solution with ammonia and drying the product, characterized in that, in order to increase the degree of use of mineral raw materials and balance the nutrient content of the product, the decomposition of phosphoric acid lead in the presence of calcium nitrate, which is taken in an amount that ensures the binding of sulfation in the minerals to gypsum.
