METHOD OF APPLYING BIOCOMPONENTS ON SURFACE OF GRANULAR NPK-FERTILIZER Russian patent published in 2025 - IPC C05G1/00 C05C3/00 C05F11/08 C05G3/40 C05G5/12 

FIELD: agriculture.

SUBSTANCE: method of applying biocomponents on the surface of a granular NPK fertilizer - a mixture of mono- and diammophos with potassium chloride of grades of composition (5–20)–(10–30)–(10–30), is characterized by that the granules are in contact with an adhesive, which is heated to temperature of 40–80 °C polymerised sunflower oil, after which the granules are brought into contact with the applied adhesive with excess powder containing spores of the following bacteria: endophytic bacteria Bacillus pumilus strain BIS88, rhizosphere bacteria Bacillus subtilis strain “Ч-13” and endophytic bacteria Bacillus subtilis strain 8A, in the form of individual strains or mixtures thereof, until the powder ceases to stick to the adhesive, after that, excess powder containing bacterial spores is separated, and finished granules are collected and packed in sealed containers.

EFFECT: invention enables to increase the biomass of bacterial strains: endophytic bacteria Bacillus pumilus strain BIS88, rhizosphere bacteria Bacillus subtilis strain “Ч-13” and endophytic bacteria Bacillus subtilis strain 8A, in soil medium for biochemical processing of components of mineral fertilizers into forms assimilated by cultivated agricultural plants, and to block growth of pathogenic bacteria in soil and cultivated plants.
