LGRB-BW INSPIRE SB: Soil - Field Capacity - Dataset

The field capacity of a soil specifies the amount of water that remains in the soil after gravity has drained all excess water following, for instance, a major rain event. It is defined as the water content of a soil at pF 1.8. Water content at field capacity as shown in this dataset is added up for all soil horizons down to 1 m below the surface and later classified into groups ranging from very low to very high. For mineral soils, field capacity values are computed by pedotransfer functions using soil texture type, humus content and effective packing density information. Share of coarse fragments and hard rock are considered as non-water holding volume. The input parameter are themselves estimates made by soil surveyors in the field from soil material collected using soil augers.
