Inspire View Service: Soil/base saturation in the effective root space Brandenburg (WMS-SO-BASEN)

The interoperable INSPIRE representation service (WMS) Soil (derived from the original dataset: Base saturation in the effective root area of Brandenburg) gives an overview of base saturation in the effective root space in the state of Brandenburg. This map is based on the legend units of the soil overview map with assignment of parameterised surface soil shapes. These represent a soil form society for each legend unit. The individual soil forms were provided with parameters, including the pH and KAC values determined by ground and laboratory tests. The same horizontal-substrate combinations were summarised and parameters (such as pH and KAC values) were statistically derived (usually the median value). The base saturation in the effective root space was derived with and without the support horizons. For different results for the soil forms of a legend unit, the area-dominant and subdominant classified values were given (see Table according to Hennings 2000, Link Rule 2.4). According to the INSPIRE data specification Soil (D2.8.III.3_v3.0), the contents of the floor map are INSPIRE-compliant. The WMS includes the following layers: — SO.baseSaturationInRootZoneDepth: Base saturation indicates the percentage of effective cation exchange capacity (KAKeff) absorbed by cations Ca2+, Mg2+, K+ and Na+. The reference depth is the effective root space, which describes the potential extraction depth of the plant available soil water. — SO.baseSaturationInRootZoneDepthWithOrganicSurfaceLayer: Base saturation indicates the percentage of effective cation exchange capacity (KAKeff) absorbed by cations Ca2+, Mg2+, K+ and Na+. The reference depth is the effective root space, which describes the potential extraction depth of the plant available soil water including the organic support. — SO.SoilBody: Demarcated and with respect to certain soil characteristics and/or spatial patterns of homogeneous part of the floor ceiling. — The compliant INSPIRE view service (WMS) Soil (derived from the original data set: base saturation in the effective root zone depth range in Brandenburg) provides an overview of the base saturation in the effective root zone in Brandenburg. This map is based on the legend units of the soil map with corresponding assignment of parameterised soil forms. These represent one soil form society per legend unit. The single soil forms were assigned with parameters, including the pH and CEC values, which were determined by field and laboratory investigations. Identical horizon-substrate combinations were summarised and the corresponding parameters (such as pH and CEC values) were statistically derived (usually the median value). The base saturation in the effective root zone was derived with and without surface layers. In the case of different results for the soil forms of a legend unit, the area dominant and the area sub-dominant classified values are displayed (see table according to Hennings 2000, Method 2.4). The content of the soil map is compliant to the INSPIRE data specification for the annex theme Soil (D2.8.III.3_v3.0). The WMS includes the following layers: — SO.baseSaturationInRootZoneDepth: Base saturation indicates the percentage of the effective cation exchange capacity (KAKeff) that is taken up by cations Ca2+, Mg2+, K+ and Na+. Reference depth is the effective root zone depth, which describes the potential extraction depth of plant-available soil water. — SO.baseSaturationInRootZoneDepthWithOrganicSurfaceLayer: Base saturation indicates the percentage of the effective cation exchange capacity (KAKeff) that is taken up by cations Ca2+, Mg2+, K+ and Na+. Reference depth is the effective root zone depth, which describes the potential extraction depth of plant-available soil water, including the organic surface layer. — SO.SoilBody: Part of the soil cover that is delineated and that is homogeneous with regard to certain soil properties and/or spatial patterns.
