Abstract
The features of structural transformations of peat humic acids in the course of mechanical activation with iron oxyhydroxides and the changes in their surface-active and adsorption properties are revealed. It is shown that the maximum biological activity of the aqueous solutions of sodium humates is manifested when the concentration of the active substance of humic acids is below the critical concentration of micelle formation.
