TYPE LOCATION: Noble County, Oklahoma; about 6 mile east and 8 miles north of Perry; 3,000 feet east and 2,450 feet south of the northwest corner of sec. 2, T. 22 N., R. 1 E.
RANGE IN CHARACTERISTICS: Solum thickness and depth to bedrock ranges from 10 to 20 inches. The mollic epipedon is 7 inches or more thick. Texture of all horizons is loam, silt loam, very fine sandy loam, or fine sandy loam and stony phases. Content of coarse fragments of sandstone ranges from 0 to 30 percent by volume. About 0 to 10 percent by volume is less than 76 mm in diameter and 0 to 20 percent by volume is more than 76 mm in diameter. Reaction of all horizons ranges from moderately acid through slightly alkaline.
The A and BA horizons have hue of 2.5YR to 7.5YR, value of 4 or 5, and chroma of 2 or 3.
The Bw horizon has hue of 2.5YR to 7.5YR, value of 4 to 6 and chroma of 2 to 6.
The Cr horizon has hue of 2.5YR or 5YR, value of 4 to 6, and chroma of 4 to 8. It is rippable sandstone interbedded with clay, siltstone, or sandy shale. Reaction ranges from moderately acid to moderately alkaline, but is noncalcareous. This material is paralithic with a high excavation difficulty. Fractures are greater than 10 cm apart. The material is dense enough to be root restrictive. Most of this material slakes in water within 15 hours.
Some pedons may have a Cr1 horizon that is non paralithic with a low to moderate excavation difficulty, and a Cr2 horizon as described above.
COMPETING SERIES: This is Loco series in the same family. Soils in similar families are Cordell, Darnell, Gerlane, Kiti, Missler, Quinlan, Rayford, Renish, Shidler, Timhill, Travertine, and Velow series. Cordell, Darnell, Quinlan, and Travertine soils lack a mollic epipedon. In addition, Cordell and Travertine soils are underlain with lithic bedrock and Travertine soils have a loamy-skeletal control section. Gerlane, Missler, and Velow soils have a solum more than 20 inches thick. In addition, Missler soils have a fine control section. Kiti, Rayford, Renish, Shidler, and Timhill soils are underlain with lithic bedrock. In addition, Kiti, Rayford, and Timhill soils have a loamy-skeletal control section. Loco soils are calcareous and moderately alkaline throughout the solum.
GEOGRAPHIC SETTING: Lucien soils are very gently sloping to steep upland soils on convex ridges and upper side slopes in the Central Rolling Red Prairies. Slopes range from 1 to 30 percent. They formed in material weathered from sandstone interbedded with clay, siltstone, or sandy shale of Permian age. The climate is dry or moist subhumid.
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: 200 to 230.
Elevation: 700 to 1500 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Shidler series and Coyle, Grainola, Kingfisher, Nash, Steedman, Stoneburg, and Zaneis series. Coyle, Grainola, Kingfisher, Nash, and Steedman soils have a solum more than 20 inches thick. In addition, Coyle, Grainola, Kingfisher, Steedman, Stoneburg, and Zaneis soils have Bt horizons. In addition, Grainola and Steedman soils have a fine control section. Coyle, Grainola, Kingfisher, Nash, Steedman, Stoneburg, and Zaneis soils usually occur on adjacent side slopes. Shidler soils occur on ridges.
DRAINAGE AND PERMEABILITY: Well drained; runoff is very high; permeability is moderately rapid.
USE AND VEGETATION: Mainly in rangeland and used for grazing for livestock. Some of the less sloping areas in complexes with deeper soils are cultivated to small grains or tame pasture. Native vegetation consists of mid and tall prairie grasses.
DISTRIBUTION AND EXTENT: Central Rolling Red Prairies of Oklahoma, Kansas, and Texas. The soil is of moderate extent.
MLRA OFFICE RESPONSIBLE: Temple, Texas
SERIES ESTABLISHED: Noble County, Oklahoma; 1947.
REMARKS: Diagnostic horizons and features recognized in this pedon are: Mollic epipedon - the zone from the surface of the soil to a depth of 8 inches (A and BA horizons).
Cambic horizon - the zone from 8 inches to a depth of 14 inches (Bw horizon).
Paralithic contact - the material encountered at a depth of 14 inches (Cr horizon).
