ABSTRACT THE cohesional strength of a wet silt loam soil from a tilled, continuous fallow plot was reduced from an original value of 0.9 kPa to 0.4 kPa by one cycle of freeze-thaw in the laboratory. The cohesion was measured with a fall-cone device. Additional cycles reduced strength only slightly. Soil water tensions of less than 9 kPa, appHed after thawing, resulted in cohesion of about 2.4 kPa. The soil regained cohesion in proportion to the logarithm of the consohdating soil water tension.
