Bodenphysikalische Untersuchungen zum Nachweis der spätpleistozänen Bodenbildung in rheinisch-westfälischen Lößgebieten

Soil physical investigations proving the late pleistocene pedogenesis in loess areas of Northrhine-Westfalia Balancing the structure of typical Braunerde- and Parabraunerde-profiles in the loess-regions of Northrhine-Westfalia soil physical investigations had confirmed that the biggest part of the solum has been clearly compacted als related to parent material. Above C-horizon there has been found a small part of Bv-horizon without compaction, characterized by distinctly increasing pore volume, especially by that of the 10–50 μm fraction, following the carbonate losses. This horizon represents an important mark in soil genesis, probably dating the border between preholozene and holozene soil forming processes. Because the disturbing effects of permafrost conditions the preholozene soil genesis is of definite importance in soil mapping and describing properties of the soils.
