The Cr horizon has hue of 2.5YR or 5YR, value of 4 to 6, and chroma of 4 to 8. It consists of alternating layers of weakly consolidated fine-grained sandstone and sandy shale. Reaction ranges from slightly acid to slightly alkaline. This material has high or very high excavation difficulty. It is dense enough to be root restrictive. Fractures are greater than 10 cm apart. It slakes in water within 15 hours.
COMPETING SERIES: These are the Coyle, Groesbeck and Klump series. Coyle soils have a solum less than 40 inches thick. Groesbeck soils have lithic contact at less than 40 inches. Klump soils have temperatures warmer than 64 degrees.
GEOGRAPHIC SETTING: Zaneis soils are on nearly level to sloping convex uplands in the Central Rolling Red Prairies. Slopes range from 0 to 8 percent. They formed in material weathered from interbedded sandstone and shale of Permian age. The mean annual precipitation ranges from 26 to 40 inches. The mean annual temperature ranges from 58 to 64 degrees F. The Thornthwaite annual PE indices range from 44 to 64. Frost free days range from 200 to 230 days. Elevation ranges from 900 to 1200 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bethany, Chickasha, Coyle, Grainola, Loco, Lucien, Mulhall, Nash, Renfrow, Stephenville, and Teller series. Bethany soils have a fine control section and occur on slightly higher broad flats. Chickasha and Coyle soils occur on similar areas. Grainola soils lack mollic epipedons, have a fine control section, have a solum less than 40 inches thick, and occur on side slopes. Loco and Lucien soils have a solum less than 20 inches thick, lack Bt horizons, and usually occur on ridge crest and upper side slopes. Mulhall soils occur on slightly lower side slopes and foot slopes. Nash soils have a coarse-silty control section, lack Bt horizons and usually occur on similar areas. Renfrow soils have a fine control section and occur on slightly higher convex ridge crests. Stephenville soils lack a mollic epipedon, have a solum less than 40 inches thick and occur on similar areas that have a savannah vegetation. Teller soils usually occur on slightly lower areas that are closer to the stream channel.
DRAINAGE AND PERMEABILITY: Well drained; moderately slow permeability; runoff is low on 0 to 1 percent slopes, medium on 1 to 5 percent slopes and high on 5 to 8 percent slopes.
USE AND VEGETATION: About half of the acreage is cultivated and the remainder is rangeland. Cultivated areas are cropped to small grains, grain sorghum, cotton, alfalfa, and tame pasture. Native vegetation is mid and tall grass prairie.
DISTRIBUTION AND EXTENT: Central Rolling Red Prairies (MLRA 80A) of Oklahoma, Kansas, and Texas. The soil is extensive.
MLRA OFFICE RESPONSIBLE: Temple, Texas.
SERIES ESTABLISHED: Carter County, Oklahoma; 1932.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon - the zone from the surface of the soil to a depth of 19 inches (A horizons and BA horizon).
Argillic horizon - the zone from 19 inches to a depth of 55 inches (Bt horizons).Paralithic contact - the sandstone bedrock contact at a depth of 59 inches.
The soil moisture regime is Udic-Ustic.
