Base saturation and sorption capacity — INSPIRE View-Service (WMS-LBGR-BOBASENSORP)

The INSPIRE View Service represents the base saturation and sorption capacity in the effective root space in the state of Brandenburg. The content presented was for scale 1: 300,000 created and are larger for representations in scales 1: 100,000 are not suitable. The service is based on the legend units of the soil overview map with corresponding assignment of parameterised surface soil shapes. These represent a soil form society for each legend unit. Base saturation: The individual (area) soil shapes were used with parameters, including the pH and KAC values necessary to derive base saturation, which were determined by ground and laboratory tests. For this purpose, the corresponding parameters (such as pH and KAC values) were statistically derived for the same horizontal-substrate combinations (usually the median value). The sequence of horizontal-substrate combinations in the surface soil forms with their ph and KAC values formed the basis for the calculation of base saturation in the effective root space (see Hennings 2000, link rule 2.4). Sorption capacity: The individual (area) soil shapes were provided with parameters, including the corresponding KAK values determined by terrain and laboratory tests. The same horizontal-substrate combinations were summarised and the corresponding parameters (such as KAK values) were statistically derived (usually the median value). The sequence of horizontal-substrate combinations in the surface soil forms with their KAC values formed the basis for the calculation of the sorption capacity in the effective root space (see Hennings 2000, link rule 2.3).
