Umbrisols

Umbrisols have a significant accumulation of organic matter in the mineral surface soil and a low base saturation somewhere within the first metre (in most cases in the mineral surface soil). Umbrisols are the logical counterpart of soils with a chernic or mollic horizon and a high base saturation throughout (Chernozems, Kastanozems and Phaeozems). Many of these soils are classified in other systems as several Great Groups of Entisols and Inceptisols (United States of America), Sombric Brunisols and Humic Regosols (France), Mountain-meadow soils (former USSR) and Mucky-dark-humus soils (Russia), Brown podzolic soils (e.g. Indonesia) and Umbrisols (Romania). In the Soil Map of the World (FAO–UNESCO, 1971–1981) most of them belong to Humic Cambisols and Umbric Regosols.
