Abstract RU 2139270 C1

FIELD: agriculture, more particularly preparation of organomineral fertilizer for various types of crops. SUBSTANCE: preammonated peat is mixed with any mineral compounds such as ammonium phosphate, carbamide potassium, magnesium and sodium sulfates. Mixing is carried out at 45-55 C for 12-25 minutes, and the resulting mixture is granulated in drum. Granulation is carried out at 50-65 C till granules with particles size of 1-4 mm are formed in amount of at least 87% of total weight. Granules are then dried. Method makes it possible to obtain certain grades of fertilizers for certain type of agricultural product. EFFECT: higher yield of commercial products and greater strength of granules. 2 cl, 3 ex
