Al–Fe-gumus soils are differing morphologically and chemically pronounced accumulation of Al-, Fe- and humic compounds. They form spodic horizon BHF brown or buff-brown tones. Coloring a horizon depends on the ratio of it organic matter and iron oxides. The Division of soils characterized by: acid reaction to the entire profile, desaturated bases, fulvic or gumic-fulvic type of humus. Al–Fe-gumus soils are distributed mainly in the taiga and tundra zones. They are formed in a free drainage on unconsolidated sandy sediments. Let's take a look at different kinds of spodosols, containing in profile spodic horizon
