The polymer tensiometer is a newly developed instrument to measure soil water pressure heads from saturation conditions to drier than the permanent wilting point. In this note we describe how the hydraulic properties of disturbed soil samples were determined in laboratory evaporation experiments with these polymer tensiometers. Soil material from the surface layer of an Ultisol was used. The relation among hydraulic conductivity, water content and pressure heads in the range from -1 to -150 m could be determined using polymer tensiometers in evaporation experiments.
