Soil Associations 1990
A complete Soil Association Map for West Berlin was prepared by Grenzius in 1984, and the map was published in the Environmental Atlas (SenStadtUm 1985). Soils in a landscape segment interact with neighboring soils, air, water, and vegetation. Grenzius did not identify individual soil types, but rather combined soil types that interact with each other in a given landscape segment (geomorphic units) into soil associations. These soil associations were studied and evaluated for their location characteristics.
The Concept Map of Soil Associations was prepared for West Berlin based on 1) the Map of Soil Associations and commentaries by Grenzius (Grenzius 1987), which define and describe soil associations, and 2) the updated Soil Association Map of 1990. The assignment of soil associations, the determination of new soil associations and concept soil associations for East Berlin were enabled by a transposition concept (Aey 1991) based on analogical conclusions, and with the aid of information from geologic and topographic maps, forest site surveys, detailed maps, aerial photography evaluations, and information about area uses and degrees of sealing. Newer soil maps and an updated map of area uses in West Berlin necessitated a reworking and updating of the map of soil associations in West Berlin. Table 3 gives the map data bases and the preliminary information used.
