METHOD FOR OBTAINING AN ORGANIC SOIL IMPROVER BASED ON VERMICOMPOST Russian patent published in 2023 - IPC A01C21/00 C05F9/04 C05F3/00 C05F11/08 

FIELD: agriculture; crop production.

SUBSTANCE: method includes the use of cattle manure and spent blocks after cultivation of Pleurotus ostreatus as a substrate: chopped straw + wood shavings + mycelium of Pleurotus ostreatus. Substrate vermicomposting is carried out in vermireactors at a temperature of 40°C, Eisenia fetida earthworm density not less than 20,000 pcs. per 1 m³. Vermicompost is mixed with water in a ratio of 1/5 and the resulting suspension is processed in a hydromill, followed by separation of the vermicompost mass. Ballast and abrasive particles are separated by cavitation treatment in a rotary pulse apparatus for 20 minutes, followed by alkaline extraction of humic substances with 0.5% potassium hydroxide to obtain a product that is a gel-like liquid with a particle size of 10-200 microns and an organic matter content of at least 15 %.

EFFECT: creation of a gel-like mass of an organic soil improver with a high content of organic matter and solubility.
