Abstract
A comparative study of the chemical composition and biostimulation activity of humic acids from natural and mechanochemically oxidized brown coals was performed. It was found that the humic acids obtained from mechanochemically oxidized coal exhibited higher biological activity in comparison with the humic acids from coal oxidized under natural conditions. In this case, they were characterized by a maximum concentration of oxygen-containing groups bound to the aromatic carbon skeleton.
