METHOD OF PRODUCING LIQUID-PHASE BIOLOGICAL AGENT FOR CROP GROWING AND AGRICULTURE Russian patent published in 2011 - IPC C05F11/02 

FIELD: chemistry.

SUBSTANCE: method of producing liquid-phase biological agent for crop growing and agriculture involves fermentation of a peat-dung mixture rich in a biologically active additive - hardwood ash in amount of 3% of the weight of the peat-dung mixture in three steps: first and third step - in 48 hours at temperature 37°C, second - for 24 hours at temperature 55-60°C. The mixture is blown with air in the longitudinal and transverse directions for 30 minutes every 24 hours, followed by extraction of the solid-phase fermentation product with 1% potassium phosphate solution for 48 hours at temperature 22°C and filtration of the extracted mass. At the end of the extraction process, sodium chloride is fed into the extracted mass in dry form in amount of 8-12 wt %. The components are mixed until complete dissolution, after which the extracted mass is held for 12 hours at temperature 22°C.

EFFECT: ready liquid-phase biological agent can retain its composition and properties for 6 months when stored at temperature 3°C.
