RAUB SERIES
The Raub series consists of very deep, somewhat poorly drained soils that are deep or very deep to dense till. The Raub soils formed in loess or other silty material and in the underlying loamy till. They are on till plains. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 940 mm (37 inches), and mean annual air temperature is about 10 degrees C (50 degrees F).

GEOGRAPHIC SETTING: The Raub soils are on till plains of Wisconsinan age. Slope ranges from 0 to 2 percent. The soils formed in 56 to 102 cm (22 to 40 inches) of loess or other silty material and in the underlying loamy till. Mean annual precipitation ranges from 813 to 1092 mm (32 to 43 inches). Mean annual air temperature ranges from 9 to 12 degrees C (48 to 54 degrees F). Frost-free period ranges from 150 to 180 days. Elevation ranges from 207 to 311 meters (680 to 1,020 feet) above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Brenton,
Chalmers,
Dana,
Drummer,
Sable, and
Toronto soils. The poorly drained Chalmers, Drummer, and Sable soils are in depressions. Brenton soils are on similar landform positions and have stratified substratums. Dana soils are moderately well drained and are on slightly higher rises. Toronto soils are on similar landform positions but have dark colored surface layers less than 10 inches thick.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. The depth to the top of an intermittent perched high water table ranges from 15 to 61 cm (0.5 to 2.0 feet) during the winter and spring in normal years. The potential for surface runoff is low. Saturated hydraulic conductivity is moderately high in the solum and low or moderately low in the dense till substratum. Permeability is moderate in the loess, moderately slow in the till subsoil, and slow or very slow in the dense till substratum.
USE AND VEGETATION: Soils are cropped to corn and soybeans. Wheat is the main small grain. Native vegetation is prairie grasses.
DISTRIBUTION AND EXTENT: West-central Indiana, east-central Illinois, and western Ohio; MLRAs 108A, 110, 111A, 111C, and 111D. The type location is in MLRA 111D. The series is of moderate extent.
