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.
