Harvard, Plano, and St. Charles soils are on nearby similar landscape. Virgil soils are generally less sloping and are somewhat poorly drained. Surface runoff is slow on the gentle slopes and rapid on the steeper slopes. Permeability is moderate in the solum and moderate or moderately rapid in the substratum. Most areas of these soils are cultivated.
Native vegetation is a mixture of prairie grasses and trees.
The extent is moderate. Kendall County, Illinois, 1941.
