ACID COMPOSITION BASED ON LEONARDITE AND AMINO ACIDS Russian patent published in 2020 - IPC C05F11/02 C05G3/00 

FIELD: agriculture.

SUBSTANCE: acid composition for use as a fertilizer, biostimulant and/or nutrient is an aqueous dispersion containing micronized leonardite, amino acids and surfactants. Method of producing composition includes following steps: a) preparation of initial aqueous solution containing antifoaming agent and surfactants; b) adding an amino acid source to the aqueous solution from step a); c) adding leonardite and dispersing said leonardite; d) wet-micronization of the dispersion obtained at step c), is characterized by that the composition has acidic pH from 3 to 6, step (b) of adding amino acids can be carried out at any time before or after the step of micronizing the aqueous dispersion.

EFFECT: inventions allow to create a composition which will be stable and functional with acidic pH without formation of precipitation of amino acids or humic acids.
