COMPETING SERIES: There are no competing series.
GEOGRAPHIC SETTING:
Parent material: These soils formed in materials weathered from shale with thin layers of interbedded sandstone and siltstone.
Landform: sloping to steep dissected uplands
Slopes: 5 to 20 percent, but can range to 30
Elevation: 500 to 1000 feet
Mean annual temperature: 57 to 63 degrees F
Mean annual precipitation: 38 to 44 inches
Frost-free period: 200 to 220 days.
Thornthwaite annual P-E index is 64 to 70
GEOGRAPHICALLY ASSOCIATED SOILS: These include the
Barden,
Eram, and
Liberal series and the
Barco,
Bates,
Collinsville,
Coweta,
Dennis, and
Vinita series. Barden, Dennis, Eram, Liberal, and Vinita soils are on landscapes in lower positions.
Bates, Collinsville, and Coweta soils are on smooth ridges and they formed in material weathered from sandstone.
All of these soils, except Collinsville and Coweta, have an argillic horizon. Collinsville and Coweta soils have less than 35 percent clay in the control section.
DRAINAGE AND PERMEABILITY:
Drainage: poorly drained
Runoff: moderate to very high
Permeability: slow
These soils have a perched water table within a depth of 0.5 to 2.0 feet for short periods of time from November to April.
USE AND VEGETATION: The primary use is native range.
The native vegetation is tall grass prairie. Scattered elm, sumac, hawthorne, persimmon, and osage-orange trees are present in some areas.
DISTRIBUTION AND EXTENT: Eastern Oklahoma, southeastern Kansas, and southwestern Missouri. The series is extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado
