Air capacity of German soils

The map of the air capacity of soils in Germany gives an overview of the content of air in a soil at field capacity. The map shows the air, which is available for plant growth from the surface to effective rooting depth, which is derived from land use and soli data. The method is published in the Bodenkundliche Kartieranleitung 4 (1994) and in the documentation of Ad-hoc-AG Boden (representing the soil experts of the geological services of the German federal states). The land use information is derived from the Corine Land Cover data set (2006).
