LOCATION GLENHALL IN
The Glenhall series consists of very deep, moderately well drained soils that formed in as much as 51 cm (20 inches) of silty material and in the underlying loamy outwash. Glenhall soils are on outwash plains and on till plains which have a layer of outwash. Slope ranges from 1 to 4 percent. Mean annual precipitation is about 940 mm (37 inches), and mean annual temperature is about 10.6 degrees C (51 degrees F).

Depth to redox depletions with chroma of 2 or less: 76 to 102 cm (30 to 40 inches)
Chroma: 1 or 2
Texture: silt loam or loam
Reaction: moderately acid to neutral depending on liming history
Value: 4 or 5
Chroma: 4 to 6
Texture: typically loam, sandy clay loam, or clay loam but ranges to silty clay loam where the thickness of the silty material is near the maximum
Rock fragment content: 0 to 12 percent
Reaction: moderately acid or slightly acid
Chroma: 4 or 6
Texture: gravelly sandy loam or gravelly sandy clay loam
Rock fragment content: 15 to 25 percent
Reaction: slightly acid or neutral
Value: 5 or 6
Chroma: 3 or 4

Rock fragment content: 3 to 14 percent
Reaction: slightly alkaline or moderately alkaline; carbonates are present in some pedons
COMPETING SERIES: These are the
Octagon series. Neda and Octagon soils have carbonates within a depth of 102 cm (40 inches).
GEOGRAPHIC SETTING: Glenhall soils are on outwash plains and on till plains which have a layer of outwash. Slope ranges from 1 to 4 percent. The soils formed in as much as 51 cm (20 inches) of silty material and in the underlying loamy outwash. Mean annual precipitation ranges from 889 to 1016 mm (35 to 40 inches). Mean annual temperature ranges from 10.0 to 12.8 degrees C (50 to 55 degrees F). Frost-free period is 150 to 180 days. Elevation is 207 to 305 meters (680 to 1,000 feet) above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the poorly drained
Drummer soils, the somewhat poorly drained La Hogue soils, and the moderately well drained
Billett soils. Drummer soils have grayer subsoils and are in depressions and swales. La Hogue soils have redox depletions at shallower depths and are on slightly lower lying rises. Barce soils have the lower part of the solum formed in till and are on similar landscape positions. Billett soils contain more sand in the solum and are on slightly higher lying landscape positions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. Potential for surface runoff is low. Saturated hydraulic conductivity is moderately high or high in the solum and high in the underlying material. Permeability is moderate in the solum and moderately rapid in the underlying material.
USE AND VEGETATION: Soils are mostly cropped to corn and soybeans. Small grain is also grown. Native vegetation is mixed forest and prairie grasses.
DISTRIBUTION AND EXTENT: MLRAs 110 and 111C in west-central Indiana. The type location is in MLRA 110. The series is of small extent.
