COMPETING SERIES: This is the Metamora series. Metamora soils typically have rock fragments in the lower part of the series control section.
GEOGRAPHIC SETTING: Headlee soils formed in loamy, water-sorted material 20 to 40 inches thick and in the underlying lacustrine materials and are on flats, low knolls, and ridges on lake plains. Slope gradients range from 0 to 1 percent. Mean annual temperature ranges from 48 to 53 degrees F., mean annual precipitation ranges from 30 to 42 inches, frost-free period ranges from 130 to 180 days, and elevation ranges from 600 to 1,300 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brady, Bronson, Gilford, Whiskerville, and Whitepost soils. The somewhat poorly drained Brady soils are on similar landforms but do not have lacustrine sediments in the lower part of the series control section. The moderately well drained Bronson and Whiskerville soils are on slightly higher positions on the landform. The poorly drained or very poorly drained Gilford and Whitepost soils are in depressions.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is negligible to low. Permeability is moderate in the upper loamy material and slow or very slow in the underlying lacustrine materials. The depth to the top of a perched seasonal high water table ranges from 0.5 to 1.5 feet from November to April in normal years.
USE AND VEGETATION: .Soils are mostly cultivated. Principal crops are corn, soybeans, wheat, and hay. The native vegetation is a mixture of deciduous forest and prairie grass.
DISTRIBUTION AND EXTENT: MLRAs 99 and 111 in northern Indiana and Ohio. 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)
Argillic horizon: from 9 to 42 inches (Bt1, Bt2, 2Bt3, 2Bt4, 2Bt5)
Aquic conditions: redoximorphic features present in the zone from 9 to 65 inches
NASIS Data Mapunit ID 155021 represents the typical pedon in complex with Brady soils.
ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S98IN-131-009) from the National Soil Survey Laboratory, Lincoln, NE. Transect data for the typical pedon (T97IN-131-187) is on file in MLRA project office, Plymouth, Indiana. Transect in a Headlee-Brady complex map unit shows 80 percent Headlee and similar soils, and 20 percent Strole soils.
