(Combined thickness of the Bt horizons is 8 to 38 inches)

TYPE LOCATION: Shiawassee County, Michigan; about 3 miles east of Corunna; 2,310 feet west and 450 feet south of the northeast corner of sec. 25, T. 7 N., R. 3 W.
RANGE IN CHARACTERISTICS: Thickness of the mollic epipedon is 8 to 15 inches. Thickness of the solum ranges from 24 to 50 inches and normally corresponds to the depth of free carbonates. Coarse fragments range from 0 to 15 percent throughout the pedon.
The Ap horizon has hue of 2.5Y, 10YR, or is neutral, value of 2 or 3, and chroma of 0 to 2. It is loam, silt loam, fine sandy loam, sandy loam, or mucky loam. Reaction ranges from slightly acid to slightly alkaline.
The Btg horizons have hue of 10YR, 2.5Y, or 5Y; value of 3 to 6; and chroma of 1 to 3. It is loam, silt loam, sandy clay loam, or sandy loam. The upper 20 inches of the argillic horizon averages between 18 and 25 percent clay and averages between 50 and 70 percent fine sand or coarser. Reaction ranges from slightly acid to slightly alkaline.
The C horizon has hue of 10YR, 2.5Y, or 5Y; value of 5 or 6; and chroma of 1 to 4. It is commonly sandy loam and less commonly loam, fine sandy loam or loamy sand. Thin strata of sand are in the C horizon in some pedons. The C horizon is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Berville, Brookston, Buntingville, Clackamas, Cordova, Hamel, Jameston, Marengo, Millgrove, Navan, Rensselaer, and Westland soils in the same family. Berville soils contain from 27 to 35 percent clay in the lower part of the argillic horizon. Brookston, Cordova soils have more than 27 percent clay in the control section, and Marengo soils contain more than 25 percent clay in the argillic horizon. Buntingville soils have mollic epipedons that range from 24 to 40 inches thick. Clackamas soils contain more than 55 percent rock fragments in the lower part of the series control section and do not have free lime. Hamel soils have mollic epipedons more than 15 inches thick. Jameston soils contain more than 25 percent clay in the series control section. Millgrove soils formed in stratified sediments and contain more than 15 percent coarse fragments at depths from 40 to 60 inches. Navan soils contain more than 25 percent clay in the lower part of the solum. Rensselaer soils contain an average of less than 50 percent fine sand or coarser in the upper argillic horizon. Westland soils contain more than 15 percent coarse fragments at depths from 40 to 60 inches.
GEOGRAPHIC SETTING: The Barry soils formed in loamy glacial till deposits and are on nearly level and depressional areas of ground moraines and end moraines. Slope gradients range from 0 to 3 percent. Mean annual precipitation ranges from 26 to 37 inches, and mean annual temperature ranges from 47 to 50 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brady, Dryden, Gilford, Lapeer, Locke, and Wasepi soils. Brady, Gilford, and Wasepi soils are associated with Barry soils in drainageways, especially on moraines. They are coarse-loamy. The well drained Lapeer, moderately well drained Dryden, and somewhat poorly drained Locke soils are in a drainage sequence with Barry soils and are in higher landscape positions.
DRAINAGE AND PERMEABILITY: Poorly drained. The soil has a seasonal high water table that ranges from 1 foot above the surface to 1 foot below the surface from November to May. The low precipitation phase has a seasonal high water table at 1 to 2.5 feet from November to July. Surface runoff is slow or ponded. Permeability is moderate.
USE AND VEGETATION: These soils are cropped to corn, small grains, soybeans, and hay where artificial drainage is adequate. Undrained areas and a small part of the drained areas are in permanent pasture or deciduous forest.
DISTRIBUTION AND EXTENT: Southern Michigan, southeastern Wisconsin, southern Minnesota and northern Indiana. The series is of moderate extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana
SERIES ESTABLISHED: Lenawee County, Michigan, 1957.
REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface to 11 inches (Ap horizon); argillic horizon - the zone from 11 to 36 inches (Btg1, Btg2, and Btg3 horizons); aquic soil moisture regime.
The shaley substratum phase is no longer within the series concept.
