The study of humus qualitative parameters has been carried out because of their importance for soil composition and soil genesis. The most significant characteristics of humus have been analysed such as its dissolving ability in soil solutions, formation of organe-mineral compounds, podzolization and overgleying of minerals, migration between soil horizons, etc. The article presents seven fractional groups of humus content in upper soil horizons in major types of Latvia's automorphic soils. Humus fractional composition in different soils is shown graphically.
