The development of a landuse-stratified soil map (BUEK1000N) at a scale of 1 : 1,000,000 aimed at both the spatial differentiation of the base map and a specification of the pedological parameters related to the main types of landuse, i. e. arable land, forest and grassland.
For this purpose, the landuse units of the CORINE Land Cover 1990 project were included in the processing. The intersection of the soil map with the spatial extent of the land use types arable land, grassland and forest, spatially generalized for the scale 1 : 1,000,000, led to the cartographic basis of the new soil map. It comprises 14 land use classes with a minimum area size of the individual polygons of approx. 4 km2. Furthermore, regional entities such as soil regions and great soilscapes have been incorporated into the map body.
The determination of area-representative soils for the landuse-specific identification of the mapping units (differentiated into arable land, grassland, forest) and the characterization of these soils by means of soil profiles was carried out in close cooperation with the State Geological Surveys of the German federal states. It is the result of analyses of soil associations in medium-scale soil maps and the evaluation of grid points of the National Forest Soil Inventory.
Extracts can be made from the landuse-stratified soil map for arable land, grassland and forest and provided with landuse-specific content. The data basis used, the processing methods and the available results are described in detail in a booklet accompanying the map.
Notes on distribution
The printed explanatory booklet with the three map extracts of arable land, grassland and forest is distributed by the International Map House in Stuttgart (order information).
