TYPE LOCATION: Tillman County, Oklahoma; About 2 miles west and 2 miles north of Tipton; 200 feet north and 2,300 feet west of the southeast corner of sec. 28, T. 1 N., R. 19 W; Latitude: 34 degrees, 31 minutes, 20 seconds N; Longitude: 99 degrees, 12 minutes, 02 seconds W; Tipton, Oklahoma USGS quad; NAD 27.
RANGE IN CHARACTERISTICS:
Soil moisture: An ustic moisture regime bordering on aridic. The soil moisture control section is dry in some or all parts for more than 90 but less than 205 days cumulative in normal years. July through August and December through February are the driest months. These soils are intermittently moist in September through November and March through June.
Mean annual soil temperature: 57 to 64 degrees F.
Solum thickness: 60 to 80 inches.
Particle-size control section: 0 to 15 percent silicate clay.
Coarse fragments: 0 to 10 percent
A horizon:
Hue: 5YR to 2.5Y
Value: 4 to 7 dry, 3 to 5 moist
Chroma: 2 to 6
Texture: loamy fine sand, sand, fine sandy loam, loam, clay loam
Effervescence: none to strong
Reaction: slightly to moderately alkaline
Note: Where the moist color value and chroma are less than 3.5, the thickness is less than 10 inches.
C horizon:
Hue: 5YR to 2.5Y
Value: 5 to 8 dry, 3 to 5 moist
Chroma: 2 to 6
Texture: sand, loamy fine sand stratified with thin strata of fine sandy loam, sandy clay loam, clay loam
Effervescence: slight to strong
Reaction: moderately alkaline
Note: The strata are less than 1 inch thick, are darker colored, and contain more organic carbon than the remainder of the soil.
COMPETING SERIES: The
Sayers (TX) series is the only competing series. Similar soils are the
Gad,
Gaddy,
Gracemore,
Guadalupe, and
Westola series.
Sayers series: is noncalcareous in the 10 to 40 inch particle-size control section.
Gad series: is moist in the soil moisture control section for longer periods of time and has mean annual temperatures of 65 to 70 degrees F.
Gaddy series: is moist in the soil moisture control section for longer periods of time.
Gracemore series: has a udic moisture regime and has a water table within 40 inches of the soil surface.
Guadalupe series: has a cambic horizon.
Westola series: has a coarse-loamy particle-size control seciton.
GEOGRAPHIC SETTING:
Parent material: sandy fluvial material of Recent age.
Landform: nearly level to undulating flood plains in the Central Rolling Red Plains and Southern High Plains Breaks.
Slopes: range from 0 to 3 percent.
Mean annual air temperature: 57 to 64 degrees F.
Mean annual precipitation: 18 to 28 inches.
Frost-free period: 185 to 230 days.
Elevation: 900 to 2700 feet.
Thornthwaite annual P-E Index Values: 31 to 44.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Gracemont (OK),
Gracemore (OK),
Heman (OK),
Jester (OK),
Likes (TX),
Tivoli (OK), and
Westola (OK) series.
Gracemont, Gracemore, and Heman soils all have water tables at or near the surface and occur on similar landscapes.
Jester and Tivoli soils lack fluventic features and occur on hummocky to duney areas.
Likes soils occur on gently undulating to rolling uplands.
Westola soils have a coarse-loamy control section and usually occurs further from the stream channel and at slightly higher elevations.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained. Rapid permeability. Surface runoff is negligible on 0 to 1 percent slopes and very low on 1 to 3 percent slopes. A water table is at a depth of 5 to 8 feet during the months of November to May. These soils are rarely to frequently flooded for very brief to brief periods during the spring and summer months.
USE AND VEGETATION: Used mainly for rangeland. Native vegetation is tall grasses with small percent of trees, mainly eastern cottonwood and tamarisk. Some areas are cultivated to bermudagrass, weeping lovegrass, winter wheat, and forage sorghums. This soil has been correlated to the Sandy Bottomland.
DISTRIBUTION AND EXTENT: Central Rolling Red Plains (sub-MLRAs-78 B and 78C) and Southern High Plains Breaks (sub-MLRA-77E) of western Oklahoma and Texas and southwestern Kansas. The soil is extensive.
MLRA OFFICE RESPONSIBLE: Temple, Texas.
SERIES ESTABLISHED: Russell County, (Russell Area), Kansas; 1903.
REMARKS: Series revised March 2002 by Mike Risinger and Charlie Cailto correct elevation, precipitation, temperature, and slope ranges.
Diagnostic horizons and features recognized in this soil are:
Ochric epipedon: 0 to 11 inches. (A horizons)
Fluventic feature: Irregular decrease in organic matter content with depth.
