METHOD FOR PRODUCING A BIOFERTILISER Russian patent published in 2022 - IPC C05F5/00 C05F11/08 C12N1/20 

FIELD: biotechnology.

SUBSTANCE: invention constitutes a method for producing biofertilisers, including the production of a liquid bacterial culture, preparation of the substrate and seeding thereof, wherein steep waters or extracts of cereal and leguminous crops, potato juice from starch plants are used as a carrier substrate, alkalised to a pH of 6.5 to 8.5, subjected to heat treatment at 90 to 120°C for 10 to 15 minutes, cooled to a temperature of 24 to 32°C, then humic acids are introduced in an amount of 0.05 to 0.005%, and monocultures of the Azotobacter, Azospirillum, Bacillus, Rhizobium, Lactobacillus genera, or a community thereof composed in any ratio, are seeded, then the bacterial suspension is mixed and directly introduced into the soil, or the bacteria are grown for 6 to 24 hours at a temperature of 24 to 35°C until a concentration of bacteria of 10⁷ to 10¹¹ cells/ml is reached.

EFFECT: expanded range of biofertilisers and carrier substrates for the production thereof.
