Description: Plant available water capacity, also known as available water-holding capacity, is a key soil attribute as it quantifies the amount of a soil's water available for plants. More precisely, the available water-holding capacity is defined as the amount of water held by soil mesopores, i.e. between field capacity (pF 1.8) and permanent wilting point (pF 4.2). Plant available water 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, plant available water 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.
