TYPE LOCATION: Grant County, Oklahoma; about 3 miles west and 1 mile north of Deer Creek; 315 feet north and 195 feet east of the southwest corner of sec. 7, T. 27 N., R. 3 W.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to more than 60 inches. The mollic epipedon is more than 20 inches thick. Concretions and soft masses of calcium carbonate occur at depths ranging from 10 to 60 inches. Depth to redoximorphic features range from 30 to 40 inches. This soil is moist for long enough duration that cracks do not open and close periodically to the soil surface.
The A or Ap horizon has hue of 10YR, value of 3 to 5, and chroma of 1 to 3. It is silt loam, loam, clay loam, or silty clay loam and ranges from moderately acid to moderately alkaline.
The Bt horizon has hue of 10YR or 2.5Y, value of 3 to 6, and chroma of 1 or 2. It is silty clay or clay and ranges from slightly acid to moderately alkaline. Iron depletions and accumulations are shades of brown, gray, or red. Slickensides occur in most pedons.
The BC horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 1 to 3. It is silty clay, clay, or silty clay loam and ranges from slightly to moderately alkaline. Iron depletions and accumulations are shades of brown, gray, or red. It is calcareous or noncalcareous.
The C horizon has hue of 10YR or 2.5Y, value of 5 or 6, and chroma of 2 or 3. It is clay, silty clay, clay loam, or silty clay loam and ranges from slightly to moderately alkaline. Iron depletions and accumulations are shades of brown, gray, or red. It is calcareous or noncalcareous.
COMPETING SERIES: These include the Benchley, Caradan, Durant and Foraker series in the same family. Soils in similar families include Abilene, Bethany, Brewer, Foard, Frankirk, Kirkland, McLain, and Renfrow series. Abilene, Bethany, Brewer, Durant and Frankirk and McLain soils have mixed mineralogy and COLE less than 0.07. In addition, Frankirk, soils have mollic epipedons less than 20 inches thick. Kirkland, and Renfrow soils have Bt horizons with hues redder than 10YR in the lower part. In addition, Kirkland and Renfrow soils have mixed mineralogy. Foraker soils have sola less than 40 inches thick.
GEOGRAPHIC SETTING: Tabler soils are on nearly level to very gently sloping concave uplands. Slope gradients are commonly 0 to 1 percent but range from 0 to 3 percent. The soils formed in calcareous loamy or clayey alluvium. Mean Annual Precipitation: 26 to 40 inches. Mean Annual Temperature: 58 to 64 degrees F. Thornthwaite Annual P-E indices: 44 to 64. Frost free days range from 190 to 230.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bethany, Kirkland, Norge, Pond Creek, Renfrow, Vanoss and Wetbeth series. Bethany, Kirkland, and Renfrow soils have mixed mineralogy and are on adjacent convex slopes. Norge, Pond Creek, and Vanoss soils are on adjacent convex slopes and have fine-silty control sections. In addition, Norge and Vanoss soils have mollic epipedons less than 20 inches thick. Wetbeth soils have a apparent water table within 60 inches of the soil surface.
DRAINAGE AND PERMEABILITY: Tabler soils are moderately well drained. Runoff is slow and permeability is very slow. This soil has episaturation with a perched water table at a depth of 7 to 12 inches in winter and early in spring.
USE AND VEGETATION: Most of these soils are used for small grains and sorghums. Native vegetation was little bluestem, big bluestem, Indiangrass, and switchgrass.
DISTRIBUTION AND EXTENT: Central Rolling Red Prairies (MLRA-80A) of north-central Oklahoma and south-central Kansas. The series is of large extent.
MLRA OFFICE RESPONSIBLE: Temple, Texas
SERIES ESTABLISHED: Grady County (Little Washita Project), Oklahoma; 1939.
REMARKS: Soil Interpretation Record: Series OK0163.
Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - the zone from the surface of the soil to a depth of 44 inches (A, Bt, and BC horizons).
Argillic horizon - the zone from 10 inches to a depth of 30 inches (Bt horizon).
Udertic - Cracks within 125 cm of the mineral soil surface that are 5 mm or more wide through a thickness of 30 cm or more for some time in most years, and slickensides or wedge shaped aggregates in a layer 15 cm or more thick that has its upper boundary within 125 cm of the mineral soil surface, or a linear extensibility of 6.0 cm or more between the mineral soil surface and a depth of 100 cm.
