COMPETING SERIES: These are the Brady, Budd, Dixboro, Wasepi, and Winamac series. Brady, Budd, Dixboro, and Winamac soils have less than 27 percent clay and more than 20 percent sand in the lower part of the series control section. Wasepi soils have rock fragments in the lower part of the series control section.
GEOGRAPHIC SETTING: Whiskerville soils formed in loamy and sandy outwash overlying lacustrine deposits on lake plains and outwash plains. Slope gradients range from 0 to 1 percent. Mean annual temperature ranges from 48 to 53 degrees F., mean annual precipitation ranges from 32 to 42 inches, frost-free period ranges from 130 to 180 days, and elevation ranges from 580 to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bronson, Headlee, Medaryville, Milford, Radioville, Strole, and Whitepost soils. The moderately well drained Bronson soils are on similar landform positions but are underlain by sand and gravel deposits. The somewhat poorly drained Headlee, Medaryville, and Strole soils are on slightly lower positions on the landform. The poorly drained or very poorly drained Milford, Radioville, and Whitepost soils are in depressional areas.
DRAINAGE AND PERMEABILITY: Moderately well drained. The potential for surface runoff is negligible. Permeability is moderately rapid in the subsoil and slow in the underlying lacustrine deposits.
USE AND VEGETATION: Soils are cropped mainly to corn and soybeans, with small areas in grass-legume hay, small grains, and permanent pasture. The native vegetation is a mixture of deciduous forest and prairie grass.
DISTRIBUTION AND EXTENT: MLRAs 98 and 111 in northern Indiana. The soils are of small extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Pulaski County, Indiana, 2001.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon (mollic intergrade): from the surface to 9 inches (Ap horizon)
Argillic horizon: from 9 to 31 inches (Bt1, Bt2, Bt3 horizons)
Udic moisture regime
The Whiskerville series was proposed for the Bronson soils with lacustrine materials in the lower part of the series control section mapped in the Pulaski County, Indiana soil survey update. Also, the Bronson series do not have a dark colored surface layer.
NASIS Data Mapunit ID 155010 represents the typical pedon in complex with Bronson soils.
ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S98IN-131-005) from the National Soil Survey Laboratory in Lincoln, NE. Transect data for the typical pedon (T97IN-131-141) is on file in MLRA project office, Plymouth, Indiana. Transect shows 70 percent Whiskerville soils and 30 percent Simonin soils.
