FIELD: agriculture.

SUBSTANCE: method for obtaining humic and mineral fertilizer is characterized by the fact that it includes crushing raw materials (brown coal or peat), grinding and mixing it with alkaline material in the form of a solid or liquid fraction, followed by leaching, and in the process of mixing, hydrogenation is additionally carried out with steam at a temperature of up to 110 °C, and additionally, a magnesium-containing finely dispersed mineral with a specific surface area of up to 150 m²/g and a pH of up to 10 is added in the amount of 80-90 wt.%, and the crushing, grinding and mixing of raw materials is carried out in a single unit - a granulator mixer while controlling the alkali content at the level of up to pH 6.1-6.8. The invention makes it possible to simplify the method for obtaining humic and mineral products with low costs for its implementation and to expand the functionality by obtaining several products simultaneously without additional stages of target products recovery.

EFFECT: simplification of production of humic and mineral products; reduction of costs.
