Humus formation and the elemental composition of macromolecules of humic acids of automorphic Siberian soils (gray forest soils, chernozems, and chestnut soils) have been considered in comparison with those of the analogous soils of the European part of Russia. It has been found that an increase in the continentality of climate leads to significant changes in the structure of humic acids in soils of similar origin in the meridional direction.
