  skos:definition """Tension infiltrometers have been widely used for in situ
determination of the field-saturated hydraulic conductivity
(Kfs) of soils under near-saturated conditions in the vadose
zone (Meiers, 2002). Near-saturated conditions refer to
measurements made over the negative pressure range, -20cm to
0.0cm, where water contents are nearly as high as those for
saturation (Reynolds and Elrick, 1991). Tension infiltrometers
determine the steady-state infiltration rate into the soil
through a porous plate on which a constant negative water
pressure (tension) is applied.
