Abstract

Functional groups and molecular fragments are identified and quantified and the paramagnetic activity of humic substances is assessed. It is shown that, compared with fulvic acids, humic acids have fewer oxygen-containing functional groups and more aromatic structures.

Key words  humic substances - structure - podzolic and bog-podzolic soils
