It is the water held between field capacity and the wilting point adjusted downward for rock fragments and for salts in solution. DEFINITION Field capacity: maximum water content expressed in percent (mass fraction or volume fraction), that an unsaturated soil can retain against gravity under undisturbed soil conditions (conventionally stated as the water content 2 to 3 days after full saturation with water). DEFINITION Wilting point: water content of the soil below which the plants are not able to uptake water with their root system. SOURCE ISO 11074 NOTE The water available capacity is a parameter to be taken into account for meeting the (i) Directive 2009/28/EC of the European Parliament and of the Council (energy from renewable resources)
