Nodine, Rollingstone, and Southridge soils have landscapes similar to Blackhammer soils. Nodine soils are fine-loamy. Rollingstone soils have thinner loess and a clayey 2B horizon. Seaton soils formed in thick loess and are on summits. Runoff is medium or rapid.
Permeability is moderate.
Most Blackhammer soils are cropped to corn, hay, and small grains. Those soils on steeper slopes are used for pasture and woodland. Native vegetation is deciduous forest with white and red oaks, hickory, and basswood being the more common species. It is of moderate extent. Houston County, Minnesota, 1981.
