Zur systematischen Stellung und Bodenentwicklung des Tschernosems des Oberrheintales und der Smonica in Rheinhessen

Systematical status and soil development of the Tschernosem des Oberrheintales and the Smonica of Rheinhessen (W-Germany) The Tschernosem des Oberrheintales and the Smonica of Rheinhessen are discussed respectively to their position in the soil system of the Federal Republik of Germany, as well as in the FAO/Unesco classification and USDA Soil Taxonomy. Both soils are subrelictic, and the recent behavior of the Smonica does not allow it to be placed among the Vertisols. The history of these soils is described as investigated by field work, palynology and micromorphology. Some connecting profiles between the exposed ones have been outlined.
