TYPE LOCATION: Payne County, Oklahoma; 5 miles north on OK-18 Highway and 1 mile east of Cushing; 600 feet south and 200 feet east of the northwest corner of sec. 11, T. 18 N., R. 5 E.
RANGE IN CHARACTERISTICS: Solum thickness is 10 to 60 inches. Depth to bedrock is more than 80 inches. Texture is loamy fine sand or fine sand. The soil is commonly noncalcareous in the upper 40 inches, but ranges to calcareous throughout.
The A horizon or Ap horizon, where present, has hue of 5YR to 10YR, value of 4 to 6, and chroma of 2 to 4. Reaction ranges from slightly acid to moderately alkaline.
The AC1 horizon, where present, has hue of 5YR to 10YR, value of 5 to 7, and chroma of 3 to 6. Reaction ranges from slightly acid to moderately alkaline.
The AC2 horizon, where present, has hue of 5YR or 7.5YR, value of 5 to 8, and chroma of 4 to 8. Reaction ranges from slightly acid to moderately alkaline.
The C horizon has hue of 5YR or 7.5YR, value of 5 to 8, and chroma of 4 to 8. Bedding strata of eolian origin are evident and cross bedding is common. Sandy alluvial sediments with loamy strata occur in some pedons below a depth of 60 inches. Reaction ranges from slightly acid to moderately alkaline. Most pedons are calcareous.
COMPETING SERIES: These are the competing Jester and Tivoli series in the same family. Soils in similar families are the Aline, Derby, Eufaula, Gaddy, Goltry, Likes, Milsand, Nutivoli, Pratt, and Sayers series. Likes Milsand, Nutivoli, and Tivoli soils are dry for longer periods. Aline, Derby, and Eufaula soils have lamellea that begin within 2 meters of the surface. Gaddy and Sayers soils have strata of finer texture within the control section. Goltry and Pratt soils have an argillic horizon. Jester soils are dry in the control section for longer periods.
GEOGRAPHIC SETTING: These very gently sloping to moderately steep soils are on hummocks and dunes. Slope gradients range from 0 to 45 percent. These soils are formed in material weathered from sandy eolian Holocene sediments. 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 200 to 230. Elevation ranges from 800 to 1500 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Derby and Gaddy series and the Amber, Canadian, Gracemore, Hawley, Miller, Reinach, and Yahola series. Derby soils are higher in elevation. Gaddy soils occur on lower flood plains adjacent to these soils. Amber and Reinach soils are coarse-silty and occur on flood plains. Gracemore, Miller, and Yahola soils are on flood plains. In addition, Gracemore soils have thin strata of finer textures in the control section. Miller soils have a fine control section. Yahola soils have a coarse-loamy control section.
DRAINAGE AND PERMEABILITY: Excessively drained; runoff is negliglible on 0 to 5 percent slopes, very low on 5 to 20 percent slopes, and low on 20 to 45 percent slopes; rapid permeability.
USE AND VEGETATION: Used mainly for rangeland and improved pasture. Improved pastures are mainly bermudagrass or lovegrass. Present native vegetation includes prairie sandreed, little bluestem, sand paspalum, sand dropseed, sand lovegrass, stinging nettle, pricklypear cactus, sand plum, American elm, redbud, chittamwood, eastern redcedar, eastern cottonwood, liveoak and post oak.
DISTRIBUTION AND EXTENT: Along major streams in the Central Rolling Red Prairies Oklahoma and Texas. The series is of small extent.
MLRA OFFICE RESPONSIBLE: Temple, Texas
SERIES ESTABLISHED: Grant County, Oklahoma; 1983.
REMARKS: These soils were formerly included in the Eufaula, Lincoln, and Tivoli series. Diagnostic horizons and features recognized in this pedon are: Ochric epipedon - the zone from the surface of the soil to a depth of 5 inches (A horizon). The true moisture subclass is udic, but since there is not a udic subgroup, typic is used.
Diagnostic Horizons and features recognized in this pedon are:
Ochric epipedon - 0 to 5 inches ( A horizon).
