Title
:
Ceramic plate with considerably low air entry value. Samples are placed with upon the plate and a defined pressure is applied on the plate. Controlled by the pressure, water flows from the samples into the plate until equilibrium is obtained. Subsequently, samples are weighted and related to the dry soil matter. The difference between gives then the volumetric water content at the defined pressure, since samples are within soil cores of defined volume.

Title
:
Samples in soil cores of defined volume (usual 100cm³) are weighted and related to the dry soil matter. The difference between gives then the volumetric water content. By dividing 1g / 100cm³ --> 1cm³ / 100cm³ --> counts between 0 and 1.
