METHOD OF PRODUCING CHELATED BIOHUMUS Russian patent published in 2024 - IPC C05F17/05 C05F17/50 C05F11/02 

FIELD: agriculture; biotechnology.

SUBSTANCE: method involves preparation of a substrate by mixing components consisting of agricultural wastes of vegetable and animal origin, placing the substrate in a vermicultivation device, introduction of worms of the Lumbricidae family into it, vermicultivation, separation of worms from the obtained biohumus. Further, the obtained biohumus is irrigated with 0.5–1% solution of chelate fertilizer at ratio of 0.5–0.65 l per 1 ton, after which the chelated biohumus is dried in natural conditions. Substrate contains 60 wt.% cattle manure and 40 wt.% wheat straw. Chelated fertilizer solution is represented by “KompleMet” additionally diluted to concentration of solid substances of 0.5–1%. Density of Lumbricidae worm population is 3–5 thousand individuals per 1 m² of compost mass. Clamp or a vermireactor is used as a vermicultivation device.

EFFECT: method ensures reduction of chemical load on soil, increase of ecological compatibility and balance of organomineral fertilizer, intensification of utilization of agricultural production wastes.
