Abstract
The biological activity of humic acids produced from the coals of the Kansk-Achinsk and South Ural basins was evaluated by means of phyto-testing in a series of laboratory and field tests. A connection between the structural group parameters of the organic acids of humic preparations (humic acids) and their biological activity was revealed in the series of field experiments at the sites characteristic of the most widespread technogenic landscapes of Siberia. It was established that in the case when humates are applied at the burrows of open-pit coal mines with the lack of moisture, it is necessary to take into account the hydrophobic-hydrophilic parameters of the preparations. Preparations with the high degree of aromaticity of humic acids are more efficient for the-reclamation of the burrows of brown coal deposits.
