METHOD OF PRODUCING LIQUID PHASE BIOLOGICAL AGENT FOR GROWTH AND DEVELOPMENT OF PLANTS Russian patent published in 2020 - IPC C05F3/00 C05F11/02 

FIELD: technological processes.

SUBSTANCE: method of producing a liquid-phase bioproduct for growth and development of plants includes solid-phase fermentation of a peat-bog mixture in ratio of components of 50:50, enriched with deciduous species ashes in amount of 3 % of the weight of a peat-dung mixture for 5 days, extraction of solid-phase fermentation product with 1 % solution of potassium phosphate during 48 hours at temperature of 22 °C and separation of extracted liquid fraction from solid fraction – sediment. Sediment is extracted three times each time for 2 hours with 1.5–2.0 % aqueous solution of potassium hydroxide in ratio 1:5 at temperature 60 °C with subsequent separation and integration of liquid extract and neutralization of the latter with orthophosphoric acid to pH 7–8. Further, the extracted liquid fraction is mixed with the combined liquid extract in ratio of 1.0:0.5. Mixture is stirred at rate of 20 rpm for 5 minutes and settled for 24 hours at temperature of 30 °C. End product is added with dry sodium chloride in amount of 8 wt%, stirred until complete dissolution and held for 12 hours at 22 °C.

EFFECT: invention provides a liquid-phase bio medium with a high level of biogenicity, nutrient and physiological properties, which widens the range of liquid-phase biological agents for growth and development of plants.
