ODELL SERIES

The Odell series consists of very deep, somewhat poorly drained soils that are moderately deep to dense till. Odell soils formed in as much as 46 cm (18 inches) of silty material and in the underlying loamy till. They are on moraines and till plains. Slope ranges from 0 to 6 percent. Mean annual precipitation is about 889 mm (35 inches), and mean annual air temperature is about 10.0 degrees C (50 degrees F).

TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Aquic Argiudolls

COMPETING SERIES: These are the Andres, Aztalan, Darroch, Francesville, Gilboa, Houstenader, La Hogue, Lahoguess, Le Sueur, Marcellon, Newhaven, and Protivin series. Andres and Aztalan soils have more than 20 percent clay in the lower part of the series control section. Darroch, Le Sueur, Marcellon, and Protivin soils do not have a densic contact within the series control section. Francesville soils commonly have a lithic contact within a depth of 152 cm (60 inches). Gilboa and Newhaven soils have sola thicker than 102 cm (40 inches). Houstenader soils have more than 14 percent rock fragments in the lower part of the series control section. La Hogue soils do not have carbonates within a depth of 102 cm (40 inches). Lahoguess soils have more than 60 percent sand in the lower part of the series control section.

GEOGRAPHIC SETTING: Odell soils are on swells on till plains and moraines of Wisconsinan age. Slope ranges from 0 to 6 percent. Odell soils formed in as much as 46 cm (18 inches) of silty material and in the underlying loamy till. Mean annual precipitation ranges from 762 to 1067 mm (30 to 42 inches). Mean annual temperature ranges from 8.9 to 11.7 degrees C (48 to 53 degrees F). Frost-free period is 130 to 180 days. Elevation is 177 to 466 meters (580 to 1,530 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brookston, Chalmers, Conover, Corwin, Francesville, Parr, Treaty, and Wolcott soils. The poorly drained Brookston, Chalmers, and Treaty soils and the very poorly drained Wolcott soils are in depressions. The somewhat poorly drained Conover soils are on similar landform positions but have a thinner dark colored epipedon. The moderately well drained Corwin and Parr soils are on slightly higher lying positions. The somewhat poorly drained Francesville soils are on similar positions but are underlain by limestone bedrock.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Potential for surface runoff is low or medium. Saturated hydraulic conductivity is moderately high in the subsoil and low in the underlying material. Permeability is moderate in the subsoil and slow or very slow in the underlying material.

USE AND VEGETATION: Soils are mostly cropped to corn and soybeans. Small grain and hay are also grown. Native vegetation is prairie grass.

DISTRIBUTION AND EXTENT: MLRAs 95B, 108A, 110, 111A, 111B, 111C, and 111D in west-central Indiana, Illinois, and western Ohio. The type location is in MLRA 111D. The series is of moderate extent.

NASIS Data Mapunit ID 154998 represents the fine sandy loam surface phase.
NASIS Data Mapunit ID 154999 represents the fine sand loam surface phase in complex with Francesville soils.

ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S99IN-007-001) from the National Soil Survey Laboratory in Lincoln, Nebraska. Transect data is on file in the MLRA Project Office in Plymouth, Indiana.
