BURSON SERIES
The Burson series consists of very shallow, well drained, moderately permeable soils derived from loamy residuum from sandstones and siltstones of Triassic and/or Permian age. The soils are on gently sloping to very steep ridges, knolls, side slopes, and erosion remnants. Slope ranges from 3 to 80 percent. Mean annual precipitation is 635 mm (25 in) and mean annual temperature is 16 degrees C (61 degrees F).
TAXONOMIC CLASS: Loamy, mixed, superactive, calcareous, thermic, shallow Ustic Torriorthents
TYPICAL PEDON: Burson loam, on a south-facing, convex, 15 percent slope, in rangeland at an elevation of about 690 m (2,260 ft). (Colors are for dry soil unless otherwise stated.)
A--0 to 6 inches; red (2.5YR 5/6) loam, red (2.5YR 4/6) moist; weak fine granular structure; slightly hard, very friable; common fine roots; few fine pores; slightly effervescent; moderately alkaline; clear smooth boundary. (Thickness of the A horizon is 5 to 25 cm [2 to 10 in])
Cr--6 to 40 inches; red (2.5YR 5/6) weakly cemented very fine grained sandstone and siltstone interbedded with shales and siltstone; red (2.5YR 4/6) moist; common grayish areas about 3 to 6 mm in diameter; few fine roots in upper part; slightly effervescent; moderately alkaline.
TYPE LOCATION: Briscoe County, Texas; 18 miles east of Silverton on Texas State Highway 256; then 2.35 miles southeast on Burson Lake road, and 200 feet south in native rangeland or 2,100 feet southeast of the southeast end of Burson Lake dam.
USGS topographic quadrangle: Turkey, Texas
Latitude: 34 degrees, 29 minutes, 30 seconds N
Longitude: 100 degrees, 58 minutes, 31.5 seconds W
Datum: NAD 27
RANGE IN CHARACTERISTICS:
Depth to sandstone or shale: 5 to 25 cm (2 to 10 in)
Solum thickness: 7 to 25 cm (3 to 10 in)
Soil moisture: An aridic moisture regime bordering on ustic. The soil moisture control section is dry in some or all parts for more than 205 days to 270 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.
Particle-size control section (weighted average):
Silicate clay: less than 35 percent
A horizon:
Hue: 2.5YR or 5YR
Value: 4 or 5 dry, 3 or 4 moist
Chroma: 2 to 8
Other features: Epipedons with moist values and chroma lower than 3.5 are less than 18 cm (7 in) thick
Texture: very fine sandy loam, loam, silt loam, sandy clay loam, clay loam, or silty clay loam
Clay content: 15 to 35 percent
Effervescence: none to slight
Reaction: slightly alkaline or strongly alkaline
Cr horizon:
Hue: 10R to 5YR
Value: 4 or 5 dry, 3 or 4 moist
Chroma: 2 to 8
Texture: weakly to moderately cemented very fine grained sandstone or siltstone interbedded with shales and siltstone
Effervescence: none to slight
Reaction: slightly alkaline or strongly alkaline
COMPETING SERIES: This is the
Regnier (NM) series. Similar soils are the
Cottonwood (TX),
Harpersville (TX),
Lacoca (NM),
Latom (TX),
Knoco (TX), and
Quinlan (OK) series.
Cottonwood series: is wetter in the moisture control section and developed in gypsum bedrock
Regnier series: has a solum of 30 to 50 cm (12 to 20 in) and receives less precipitation during the spring
Harpersville and
Knoco series: have 35 to 60 percent clay throughout the solum
Latom and
Lacoca series: have a lithic contact over sandstone bedrock
Quinlan series: has a cambic horizon and solum thickness averages 38 cm (15 in)
GEOGRAPHIC SETTING:
Parent material: loamy residuum from sandstones and siltstones (redbeds) of Triassic and/or Permian age
Landscape: Dissected plains
Landform: moderately sloping to steep ridges, knolls, side slopes, and erosion remnants
Slopes: dominantly 15 to 45 percent, but ranges from 3 to 80 percent
Mean annual air temperature: 14 to 18 degrees C (57 to 64 degrees F)
Mean annual precipitation: 508 to 711 mm (20 to 28 in)
Frost-free period: 180 to 230 days
Elevation: 305 to 762 m (1,000 to 2,500 ft
Thornthwaite annual P-E Index Values: 28 to 40
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Aspermont (TX),
Berda (TX),
Glenrio (TX),
Knoco,
Obaro (TX),
Quay (NM),
Quinlan,
Tascosa (TX), and
Woodward (OK) soils.
Aspermont,
Berda,
Glenrio,
Obaro,
Quay, and
Woodward soils: have cambic horizons and all but Glenrio have sola more than 50 cm (20 in) thick
Tascosa and
Quay soils: have calcic horizons
Aspermont and
Woodward soils: are on more gently sloping ridges, knolls and side slopes
Berda and
Tascosa soils: are on more gently sloping landforms and developed in alluvium and colluvium derived from the Ogallala
Formation of Miocene-Pliocene age
Knoco soils: are on side slopes typically at lower elevations
Obaro and
Quinlan soils: are on adjacent, more gently sloping benches, footslopes, knolls and ridges
Glenrio and
Quay soils_ are on nearly level to gently sloping landforms and are restricted to a drier climate on the western margin of the Southern High
Plains escarpment
DRAINAGE AND PERMEABILITY: Well drained. Moderate permeability. Surface runoff is low on 3 to 5 percent slopes, medium on 5 to 20 percent slopes, and high on slopes greater than 20 percent.
USE AND VEGETATION: Most areas are used as native rangeland and support only a sparse vegetative cover. The dominant species are sideoats grama, hairy grama, little bluestem, tridens, threeawn, black grama, and juniper shrubs.
DISTRIBUTION AND EXTENT: LRR H-Central Great Plains Winter Wheat and Range Region; Central Rolling Red Plains (sub-MLRA-78B) of Texas and Oklahoma, and Southern High Plains Breaks (sub-MLRA-77E) of Texas. Burson soils are of moderate extent.
