OUIATENON SERIES
The Ouiatenon series consists of very deep, somewhat excessively drained soils that formed in calcareous, sandy and gravelly alluvium on flood plains. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 914 mm (36 inches), and mean annual air temperature is about 10 degrees C (50 degrees F).
TAXONOMIC CLASS: Sandy, mixed, mesic Fluventic Hapludolls
TYPICAL PEDON: Ouiatenon loamy sand, on convex, 1 percent slope in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 30 cm (0 to 12 inches); very dark gray (10YR 3/1) loamy sand, dark grayish brown (10YR 4/2) dry; moderate medium granular structure; very friable; few gravel; slightly effervescent; moderately alkaline; abrupt smooth boundary.
A--30 to 41 cm (12 to 16 inches); very dark grayish brown (10YR 3/2) loamy sand, dark grayish brown (10YR 4/2) dry; weak medium subangular blocky structure; very friable; thin very dark gray (10YR 3/1) organic coatings on faces of peds; 3 percent fine gravel; strongly effervescent; moderately alkaline; clear smooth boundary. [Combined thickness of the A horizon is 25 to 61 cm (10 to 24 inches).]
AC--41 to 51 cm (16 to 20 inches); dark brown (10YR 3/3) coarse sand, brown (10YR 5/3) dry; weak medium subangular blocky structure; very friable; thin very dark grayish brown (10YR 3/2) organic coatings on faces of peds; 10 percent fine gravel; strongly effervescent; moderately alkaline; clear wavy boundary. [8 to 25 cm (3 to 10 inches) thick]
C1--51 to 122 cm (20 to 48 inches); brown (10YR 4/3) coarse sand with one 5 cm (2 inches) thick layer of very gravelly sand; single grain; loose; 10 percent fine gravel; strongly effervescent; moderately alkaline; clear smooth boundary. [25 to 114 cm (10 to 45 inches) thick]
C2--122 to 152 cm (48 to 60 inches); brown (10YR 4/3) very gravelly coarse sand; single grain; loose; 38 percent gravel; strongly effervescent; moderately alkaline.
TYPE LOCATION: Tippecanoe County, Indiana; 1,000 feet west and 850 feet south of the northeast corner of sec. 21, T. 22 N., R. 4 W.
RANGE IN CHARACTERISTICS:
Series control section: slightly alkaline or moderately alkaline with carbonates present throughout
Ap or A horizon:
Hue: 10YR
Value: 3
Chroma: 1 to 3
Texture: fine sandy loam, sandy loam, or loamy sand; thickness of sandy loam or fine sandy loam layers is less than 41 cm (16 inches)
Rock fragment content: 0 to 10 percent
AC, upper part of C horizon:
Hue: 10YR
Value: 3 to 5
Chroma: 3 or 4
Texture: loamy sand, sand, or coarse sand
Rock fragment content: 5 to 14 percent
C horizon below a depth of 102 cm (40 inches):
Hue: 10YR
Value: 3 to 5
Chroma: 3 or 4
Texture: gravelly or very gravelly analogs of loamy sand or coarse sand
Rock fragment content: averages 15 to 59 percent
COMPETING SERIES: This is the
Chatterton series. Chatterton soils do not have carbonates within a depth of 51 cm (20 inches) and average less than 5 percent rock fragments in the upper part and less than 15 percent rock fragments in the lower part of the series control section.
GEOGRAPHIC SETTING: The Ouiatenon soils are on flood plains in areas of Wisconsinan glaciation. Slope ranges from 0 to 2 percent. They formed in calcareous, sandy and gravelly alluvium. Mean annual precipitation ranges from 889 to 965 mm (35 to 38 inches). Mean annual air temperature ranges from 10 to 11 degrees C (50 to 52 degrees F).
GEOGRAPHICALLY ASSOCIATED SOILS: The Ouiatenon soils are commonly associated with somewhat poorly drained
Ceresco and very poorly drained or poorly drained
Cohoctah soils. These soils are on lower lying flood plains away from stream channels. Ceresco and Cohoctah soils have gravelly substrata where they occur on nearby landforms associated with Ouiatenon soils.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat excessively drained. The potential for surface runoff is negligible. Saturated hydraulic conductivity is high or very high. Permeability is rapid or very rapid.
USE AND VEGETATION: Most areas of this soil are used for woodland or are planted to corn and soybeans. Some areas are used for hayland or pasture. Native vegetation is deciduous forest.
DISTRIBUTION AND EXTENT: West-central Indiana; MLRA 111D. The series is of small extent.

SERIES ESTABLISHED: Tippecanoe County, Indiana, 1993.
REMARKS: Diagnostic horizons recognized in this pedon are:
Mollic epipedon: from the surface to a depth of 41 cm (Ap, A horizons).
A sandy substratum phase averaging less than 15 percent gravel below 40 inches is recognized.
