These are the Blackhammer , Lamoille , Nodine , Rollingstone , Seaton , and Valton soils. Blackhammer soils are fine-silty and on similar positions. Lamoille soils lack contrasting textures and are on steep and very steep hill slopes. Rollingstone, Seaton, and Valton soils are on similar positions. Runoff is medium on the gentle slopes and rapid on the steeper slopes.
Permeability is moderate in the upper part and slow in the lower part of the solum.
Most of Southridge soils are cultivated. Corn, alfalfa hay, and small grain are the principal crops. The remaining areas are used for pasture or woodland. Native vegetation was deciduous forest, with white oak, northern red oak, basswood, and hickory being the more common species. The soils of this series are of moderate extent.
