Map of sulfatous soils in Schleswig-Holstein in scale 1:250,000

The map of sulphate acid soils shows the distribution frequency of sulphate acid soils in Schleswig-Holstein on a 5-stage scale from very rare occurrence to highly widespread occurrence. The map is based on an evaluation of the soil map 1:250,000 from Schleswig-Holstein (BÜK250). This has been done as follows: Depending on their soil type socialisation and geological stratification, the soil societies identified in the BÜK250 have been assigned a probability of occurrence in levels ranging from 0 to 5. For level 5 areas, the proportion of sulphate-saur soils is particularly high (strongly widespread), and in the area of level 1, their proportion is very low. The map distinguishes: — Very rare occurrence (level 1) — Rare occurrence (level 2) — Low incidence (level 3) — Wide occurrence (level 4) — Highly widespread occurrence (level 5). The biggest jump is between levels 3 and 4. While it is not possible to expect a regular occurrence of sulphate-saturated soils for Stage 3, the probability of encountering sulphate-acid soils is significantly increased at Stage 4.
