Field trials were made to test the applicability of a recently proposed method for measuring the unsaturated hydraulic conductivity (K) of crust-capped soil materials in a one-dimensional flow system, where the matric suction gradient is zero. K-values were determined from infiltration rates into crust-capped soil columns carved out in situ 30 cm in height. Matric suctions were measured with tensiometers. Examples are given for four Wisconsin soil horizons.
