Usable field capacity in effective root space in Germany

The map of the usable field capacity in the effective root space in Germany gives an overview of the ability of soils to store plant-available water. The size of the water reservoir of the soil depends on the type of soil, the storage density and the humus content. The effective root space is determined by land use and soil data. The map is based on the evaluation of the utilisation-differentiated soil overview map 1:1,000,000 (BUEK1000N) and shows the classified usable field capacity. The method is published in the Soil History Carting Instructions (KA4) and in the Method Documentation Soil Science of the Ad-hoc-AG Boden. Data from the CORINE Land Cover Project (2006) are used as land use information and for the usage-dependent differentiation of profile data.
