Crawleyville and Starks soils are somewhat poorly drained and are in positions below the Ridgway soils. Hickory soils formed in less than 20 inches of loess and the underlying till and are on steep valley slopes above Ridgway soils. Alvin and Skelton soils are on similar landforms as Ridgway soils. Sexton soils are poorly drained and Geff soils are somewhat poorly drained and are in the hydrosequence with Ridgway soils. The potential for surface water runoff is negligible to medium.
Permeability is moderate in the upper part of the profile and rapid in the lower part.
Ridgway soils are used mainly for cultivated crops. The soils formed under mixed hardwood forest vegetation. The extent is small. White County, Illinois, 1990.
