Sudbury soils are moderately well drained. The potential for surface runoff is low to medium. Permeability is moderately rapid in the solum and very rapid in the substratum. In pedons that have a loamy substratum, permeability of the substratum below 40 inches is rapid. Most of these soils have been cleared and are used for crops, or are in suburban development.
Principal crops are potatoes, cauliflower, cabbage, corn, and hay.
