摘要：

The structure of humic and fulvic acids from podzolic and bog-podzolic soils was studied. It was found that the development of hydromorphism results in the enrichment of humus substances with aliphatic fragments. The agricultural development of soils increases the portion of aromatic components and decreases the content of carboxylic and ester groups in the structure of humus substances. Humic acids from paleopedorelics are enriched with aromatic fragments and oxygen-containing functional groups.
