Potential compression sensitivity of the soil in 35 cm reference depth of the state of Brandenburg — INSPIRE Download-Service (WFS-LBGR-VERDICHTEMPFINDL)

The INSPIRE Download Service provides an overview of the potential compaction sensitivity of the soil in a reference depth of 35 cm. It is based on the legend units (LE) of the soil overview map (BÜK300) with corresponding allocation of parametrised floor shapes. The individual Surface Floor Forms (FBF) were provided with soil physical characteristics, which were determined by field and laboratory tests. For this purpose, the characteristics of soil type, humus and carbonate content, skeletal content, dry raw density, water content at field capacity and effective rooting depth were statistically derived for the same Horizon-Substrate combinations (usually median values). In addition, the following input data were taken into account: Upper edge Gr horizons, soil-based moisture level, climatic water balance. The evaluation method 1.1 of the method documentation Soil Science (AG Boden, 2010) was used to estimate the potential compression sensitivity (Sm) in 35 cm reference depth. This classifies the first compaction behaviour (in the sense of compaction intensity) of a naturally stored, segregated subsoil due to its physical and hydrological properties and is applicable to both agricultural and forestry soils. The basis of the qualitative assessment is the basic classification of the potential compression sensitivity per HSK according to the soil type.
