Amboy, Wallington, and Williamson soils have fragipans and formed in silty glaciolacustrine sediments. Elnora and Stafford are moderately well drained and somewhat poorly drained soils in a drainage sequence with Colonie soils. Well drained to excessively drained. The potential for surface runoff ranges from negligible to medium. Permeability is moderately rapid or rapid.
Some areas are in woodlots of sugar maple, red oak, and other hardwoods.
Large areas are idle and are covered with poverty grass, quack grass, annual weeds, and shrubs such as sumac. Locally, the soil is used intensively for growing vegetables and deciduous fruits, and less intensively in other places for growing corn and hay. The soil is moderately extensive.
