Sudbury soils are moderately well drained. Runoff is slow 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 and corn.
The soil is of large extent. Suffolk County, New York, 1970.
