COMPETING SERIES:
Carl (T) (MO): Carl soils are on nearly level (0 to 1 percent), slightly concave terraces adjacent to streams on upland derived from a thin mantle of silty loess over clayey alluvium over gravelly alluvium.
Clearwater (MN): Clearwater soils are in the frigid temperature regime and has 2 to 8 percent rock fragments throughout and formed in till.
Fargo (ND): Fargo soils are in the frigid temperature regime and formed in lacustrine sediments.
Judice (LA): Judice soils are in the hyperthermic temperature regime.
Pitvar (CA): Pitvar soils are in the mesic temperature regime.
Terouge (AR): Terouge soils are on flood plains and low terraces. They formed in alluvium from Blacklands, or intermingled areas of Blackland and Coastal Plain, MLRAs 135 and 133B. Slopes range from 0 to 3 percent. Average annual temperature near the type location is about 63 degrees F.; average annual precipitation is about 49 inches.
GEOGRAPHIC SETTING:
Landscape: major streams in River Valley
Landform: flood plains
Slope: 0 to 2 percent
Parent material: clayey alluvium
Mean Annual Air Temperature: 59 to 65 degrees F.
Mean Annual Precipitation: 38 to 44 inches
Thornwaite Annual PE Index: greater than 64.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the coarser-textured Cleora, Hepler, Lanton, Mason, McCune, Verdigris, and Wynona soils and the lighter-colored Lighting soils that are on nearby flood plains or low terraces.
DRAINAGE AND PERMEABILITY:
Drainage: Poorly drained.
Runoff: low or very low.
Permeability: very slow.
USE AND VEGETATION: Soils are cropped to wheat, soybeans, and corn. Native vegetation was mostly tall grass prairie and in some locations deciduous hardwoods and understory of grasses.
DISTRIBUTION AND EXTENT: Southwestern Missouri, southeastern Kansas, and eastern Oklahoma. The series is extensive.
