METHOD OF PRODUCING BIOLOGICAL FERTILISER Russian patent published in 2018 - IPC C05F3/00 C05F11/02 

FIELD: biotechnologies.

SUBSTANCE: invention relates to biotechnology, agricultural microbiology. Method for producing biofertilizer includes pre-grinding chicken manure and peat, taken in a ratio of 50:50 components to a granulometric composition but not more than 10 mm followed by their mixing and alkalinization with 0.5 % aqueous solution of potassium hydroxide in an amount of 1.5 liters per 1 kg of the mixture at a temperature of 20–22 °C for 24 hours. Wheat bran in an amount of 3 % by weight, magnesium acetic acid in an amount of 0.1 % by weight % of the mixture and citric acid in an amount of 0.1 % by weight of the mixture are introduce simultaneously in the obtained primary biofertilizer. Mixture is agitated. First stage of the bioconversion of the mixture is carried out at a temperature of 36–39 °C for 96 hours. Then the second bioconversion step is carried out at a temperature of 55–60 °C for 24 hours. At the same time, every 24 hours, the mixture is agitated with air in the longitudinal and transverse direction for 30 minutes.

EFFECT: invention provides a new biofertilizer for improving the growth and development of plants enriched with a complex component stimulant represented as magnesium acetic acid and citric acid.
