Soil map of Lower Saxony 1: 50 000

The BK50 describes the distribution of the soils of Lower Saxony in high resolution and in the current state of knowledge. With the creation, numerous knowledge could be gained new and clarified old ones. The aim is to present the complex relationships around the ground professionally correct, comprehensible and transparent for the professional public and the layperson. The BK50 is closely coordinated with other maps and databases available throughout the country. A uniform set of rules ensures comparable quality throughout the country. With 13,000 legend units and 196,000 areas, the BK50 has a large technical and spatial depth of statement. It thus meets the requirements of medium-sized ground maps. The BK50 divides Lower Saxony into 6 soil regions, 13 large soil landscapes and further into soil landscapes. These land-based aggregation levels are gradually displayed according to scale. From a scale of 1:128,000, the NIBIS map server displays the ground types of the BK50 and thus the most small-scale mapping units. The map is characterised by, among other things, a high spatial differentiation of soil types, an updated moor spread with consideration of the soil levels and soils following soils of crop soils (e.g. deep breakage, plaggenesch, spitt culture soils, marsh hoof soils), as well as the designation of culturally significant areas and regional peculiarities (e.g. sausages, dyke lines). With the systematic application of the top layer division, flat-grown soils (endzines, tendrils, flat brown earths and parabrown soils) are described more precisely and spatially. The soil map contains information on the guide floor shape and associated soil forms and is differentiated in use. With the utilisation differentiation, the characteristics, horizons and soil types are adapted to the respective uses. This affects e.g. the upper soil horizons, the humus surfaces under the forest, the groundwater levels and the wetting information as well as, if necessary, soil erosion under arable land.
