Reaction is slightly alkaline or moderately alkaline. The Ayrshire, Capac, Warnut, and Whitaker soils average less than 15 percent rock fragments in the lower part of the series control section. The Crawleyville, Mongle and Jimtown soils are more acid than slightly alkaline in the lower part of the series control section. The Mitiwanga and Shadeland soils have lithic contacts in the series control section. The Sleeth soils do not have subhorizons in the lower part of the control section with less than 85 percent sand and commonly are more than 44 inches to the base of soil development.
Digby soils are on terraces and outwash plains.
Slope is typically 0 to 4 percent but ranges to 6 percent. They formed in loamy and gravelly outwash and the underlying gravelly, loamy, and sandy outwash. The well drained Belmore, moderately well drained Haney, and very poorly drained Millgrove soils are part of a toposequence with the Digby soils. Belmore and Haney soils are on higher positions in the landscape, and Millgrove soils are in depressions. Somewhat poorly drained.
