Abstract
Soil moisture tensions, diffusivities, and conductivities in packed columns of Grenville silt loam during wetting were compared with those during drying. In the moisture range 0.3 to 0.4 cm 3 /cm 3 tensions on wetting were only one third of those on drying. Diffusivities and conductivities on wetting exceeded those on drying in the ratios 5:1 and 10:1 respectively. These data depended on the bulk density and particle size distribution of the soil. The observed wetting to drying ratios of D and K should be representative for fragmented surface soils although lower ratios may occur below plow depth.
