METHOD FOR OBTAINING GRANULATED ORGANIC FERTILIZER FOR INCREASING SOIL FERTILITY IN CULTURING CROPS Russian patent published in 2023 - IPC C05F3/00 A01C3/00 

FIELD: agriculture.

SUBSTANCE: method for obtaining granular organic fertilizer to increase soil fertility in the cultivation of crops includes supplying a raw material component of organic fertilizer, mixing, disinfection and drying, whereas chicken manure with a moisture content of 50-60% is used as an organic fertilizer, bringing it to a moisture content of 13-14% and disinfection at a temperature of 70-90°C for 60-80 minutes, while to obtain granulated fertilizer, the Solovey-6 flat-matrix granulator is used for granulation, which combines one common technological line, the obtained granules are 8-12 mm long and have a diameter of: 6, 8, 10 mm are scattered before cultivation at a dose of 0.5 t/ha, if green crops growing on the field are cultivated, the predecessor is pumpkin crops, if potatoes of the SKARB variety are cultivated, then the granules are applied by scattering on the soil surface, the predecessor is spring wheat, before cultivation at a dose of 2.0 t/ha, and mineral fertilizers at a dose of N₁₄₀P₁₀₀K₂₂₀ kg a.r./ha, then planting potatoes of the SKARB variety is carried out when cutting the ridges, in the third decade of May with a density of 52 thousand tubers per 1 ha, respectively, the potatoes are treated by spraying with a solution of the Panther herbicide at a dose of 1 l/ha, protection against late blight with a triple treatment with Ridomil Gold at a dose of 0.3 l/ha, and protection against the Colorado potato beetle with the Biskay preparation at a dose of 0.3 l/ha.

EFFECT: invention allows to develop a method for fast, safe processing of chicken manure to obtain a pure organic granular fertilizer, which increases soil fertility with high and high-quality yields.
