Neckar-Rhine plain
The Neckar-Rhine plain denotes a natural spatial main unit (224) on the lower terrace of the Upper Rhine Rift (D 53 according to BfN / 22 Northern Upper Rhine Lowland according to the Handbook of the Natural Spatial Structure of Germany ) in the south-west German layer level country . It extends from the exit of the Neckar from the sandstone Odenwald (144) through the Bergstrasse (226) near Heidelberg to the entry into the Rheinauen (222 Northern Upper Rhine Lowlands) in the west with the alluvial fan that tapers flat into the plain . The area continues to border theHessian Rhine Valley (225) in the north and the Hardt levels (223) in the south and is divided into the larger subunit Neckarschwemmkegel (224.2), and the Schwetzingen sand (224.1).
It is characterized by deep loam and alluvial loess soils , Ice Age sands and gravels , which are covered by up to seven meters of calcareous clay. In the gullies of the former Neckar courses, there are very humus to boggy soils, such as humus parabroun soils and brown floodplain soils made of silty loam over lime-rich silt , which allow intensive agricultural use.
The characteristic floodplain forests of the hardwood and softwood floodplains in the floodplains of the lower Neckar are rarely found.
