摘要
The composition and properties of humic acids in permafrost-affected meadow-chernozemic soils of the Transbaikal Region have been studied. The contents of carbon, nitrogen, and acid functional groups in the humic acids of the studied soils formed under the impact of cryogenic factors are relatively low. Thus, both the condensed nuclear part and the aliphatic chains are well pronounced in the humic acids of the studied soils. At the same time, the degree of their aromaticity is lower in comparison with humic acids in the analogous soils of Western Siberia and Kazakhstan.
