The soil moisture regime was studied in two paired sets of sites in northern Wisconsin. In comparison of a forested and non‐forested Spencer silt loam there was less available soil moisture in the surface 1 to 2 feet of the forested site because of heavy depletion of soil moisture by the tree stand, as compared with the nearby site with a timothy hay crop. Bulk density of the soil in the hay land was 25% greater for the top foot and 32% greater for the top 2 feet than the forested site. In a comparison of two paired forested sites both on sands and with permanent water table at 2.0 and 4.5 feet respectively, there was around 0.4 inch more water in the surface foot in the former, or around 4% on a weight basis in the top 2 feet during much of the growing season. Jack pine had almost the same site index on both sites, but in the case of aspen, the site index was 10 feet greater on the shallower water table area.
