Soils worthy of protection in Lower Saxony 1 : 50 000 - Soils with high natural soil fertility (WFS Service)

Description

Soils that are particularly worthy of protection include soils that fulfil the natural functions as well as the archiving function to a particular extent. According to soil protection law, impairments of these functions should be avoided (cf. §1 BBodSchG). A key factor in assessing a soil's habitat function is its natural fertility. It characterizes the potential of the soil for the production of biomass. Soils with very high natural soil fertility are considered particularly worthy of protection. They enable land management with low inputs. This in turn contributes to the sustainable safeguarding of the performance of the natural balance. The designated specially protected floors on the basis of the BK50 represent search spaces on a scale. If necessary, these can be differentiated in more detail within the framework of large-scale mapping. The methods for determining the protection of soils in Lower Saxony are described in detail in Geoberichte 8 (Bug et al. 2019) is described. The evaluations are based on the soil map of Lower Saxony 1 : 50 000 (BK50). These are soils with a high to extremely high soil fertility in a national comparison (levels 5-7). In order to meet the different landscapes of Lower Saxony, the analysis is differentiated according to soil regions (cf. georeports 8). The evaluation is carried out using the NIBIS® evaluation method ‘soil fertility’ (cf. georeports 19). It determines soil fertility on the basis of the soil water balance and the nutrient supply of a site. The assessment is differentiated for arable, grassland and forest soils over the different effective root space of the vegetation. Soils with a regionally high fertility, but which have only a medium fertility in a national comparison, can only be covered to a limited extent with this approach. For regional or municipal considerations, Geoberichte 26 offers an adapted methodology.
