COMPETING SERIES: There are no other series in this family.
GEOGRAPHIC SETTING: Medaryville soils formed in loamy and sandy water-sorted materials 20 to 40 inches thick and in the underlying lacustrine materials. They are on flats and swells 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 580 to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brady, Gilford, Headlee, Milford, Mermill, Radioville, Rensselear, Whitepost, and Whiskerville soils. The poorly drained or very poorly drained Gilford, Mermill, Milford, Rensselaer, and Whitepost soils are in depressions. The somewhat poorly drained Brady and Headlee soils are on similar landforms. The moderately well drained Whiskerville soils are on higher swells.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is low. Permeability is moderate in the upper loamy and sandy materials 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. Corn, soybeans, wheat, and hay are the principal crops. Native vegetation is prairie grasses (tall grass prairie).
DISTRIBUTION AND EXTENT: MLRA 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:
Mollic epipedon: from the surface to 11 inches (Ap)
Argillic horizon: from 11 to32 inches (Bt1, Bt2, Bt3, Bt4)
Aquic conditions: redoximorphic features present between 11 and 84 inches
The Medaryville series was proposed for the Darroch soils with lacustrine materials in the lower part of the series control section, mapped in the Pulaski County, Indiana soil survey update. Transects and laboratory data supported a sandy over loamy particle-size class with some inclusions of pedons that have the strongly contrasting textural change below 40 inches.
NASIS Data Mapunit ID 155029 represents the typical pedon.
ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S99IN131-005) from the National Soil Survey Laboratory in Lincoln, NE. Transect data for the typical pedon (T00IN-131-002) is on file in the MLRA project office, Plymouth, Indiana. Transect shows 80 percent Medaryville soils, 10 percent Strole soils, and 10 percent Milford soils.
