Eufaula soil and landscape
Soil profile: Profile of Eufaula loamy fine sand. Lamellae begin to occur at a depth of about 90 centimeters. The Bt part (lamellae) of the E&Bt horizon is strong brown, yellowish red, or red. Texture is fine sand or fine sandy loam. The lamellae are thin, wavy, and generally horizontally continuous. (Soil Survey of Robertson County, Texas; by Harold W. Hyde, Natural Resources Conservation Service)
Landscape: Horses grazing on improved bermudagrass in an area of Eufaula loamy fine sand, 1 to 5 percent slopes. Eufaula soils are dominantly used for range. Considerable amounts of Eufaula soils with a the loamy fine sand surface on lesser slopes are cropped to sorghums, small grains, and peanuts; or used for tame pastures. Native vegetation is post oak and blackjack oak with an understory of mid and tall grasses.
SETTING:
Landform: Stream terrace
Landscape position: Broad, smooth areas
Slope: Very gently sloping or gently sloping; convex surfaces
Shape of areas: Elongated or irregular
Size of areas: 20 to 200 acres
Typical Profile
Surface layer:
0 to 7 inches—brown, moderately acid loamy fine sand
Subsurface layer:
7 to 15 inches—pale brown, moderately acid loamy fine sand
15 to 31 inches—very pale brown, moderately acid loamy fine sand
Subsoil:
31 to 80 inches—very pale brown, strongly acid loamy fine sand that has lamellae of strong brown fine sandy loam
Soil Properties
Depth: Very deep
Drainage class: Somewhat excessively drained
Water table: None within a depth of 6 feet
Flooding: None
Runoff: Negligible
Permeability of most restrictive layer within a depth of 60 inches: Rapid
Available water capacity: Low
Root zone: Very deep
Natural soil fertility: Low
Shrink-swell potential: Low
Hazard of water erosion: Moderate
Composition
Eufaula soil and similar inclusions: 80 to 90 percent
Contrasting inclusions: 10 to 20 percent
Use and Management
Major land use: Rangeland
Other land uses: Pastureland and cropland
Pasture
Major limitations:
• The low available water capacity limits the growth of improved grasses during periods of drought.
• Because of the rapid permeability of the soil, there is a high rate of leaching and a more costly fertilization program is required.
• Seepage is a problem for livestock ponds, and construction is not recommended.
Minor limitations:
• Water erosion is a moderate hazard during seedbed preparation for improved grasses.
Cropland
Major limitations:
• Because of the low available water capacity, this soil poorly is suited to most crops. The soil, however, is suited to the production of watermelons and peanuts.
Minor limitations:
• Water erosion is a moderate hazard when this soil is cultivated.
• When dry, the soil is loose and provides poor traction for farm machinery.
Rangeland
Major limitations:
• The low available water capacity limits the growth of native plants during periods of drought.
• The low natural fertility limits the yield potential of native plants.
• Seepage is a problem for livestock ponds, and construction is not recommended.
Interpretive Groups
Land capability classification (nonirrigated areas): 4s
