Collamer, Dunkirk and Niagara soils formed in fine-silty lake deposits. Colonie, Elnora and Stafford soils formed in sandy deposits lower in silt and clay content than Arkport soils. Galen, Minoa and Lamson soils are in a drainage sequence with Arkport soils and are in lower lying landscape positions. Howard and Palmyra soils are on nearby glacial outwash terraces that are gravelly. Runoff is slow to rapid.
Permeability is moderately rapid.
Most of the acreage is cultivated. The dominant crops are corn, hay, and small grains but vegetable crops and deciduous fruits are prominent in many places. Some areas remain in woodlots of sugar maple, red oak, and American beech. The Arkport series is of large extent. Steuben County, New York, 1931.
