Bw4--33 to 52 inches; yellowish red (5YR 5/6) sand; weak coarse prismatic structure parting to weak fine and medium subangular blocky; loose, very friable; common fine roots; common fine pores; few fine and medium prominent pink (7.5YR 7/4) iron stains with clear boundaries on surfaces of peds; few fine prominent pinkish gray (7.5YR 7/2) albic materials along root channels and on surfaces of prisms; very strongly acid; diffuse irregular boundary.
Bw5--52 to 80 inches; strong brown (7.5YR 5/8); weak coarse prismatic structure; loose, very friable; common medium pores; few fine prominent pink (7.5YR 7/4) iron stains on surfaces of peds; few fine pinkish gray (7.5YR 7/2) albic materials on surfaces of prisms; very strongly acid. (Combined thickness of the Bw subhorizons is 43 to 65 inches thick.)
TYPE LOCATION: Hardin County, Texas; from the intersection of Texas Highway 327 and Farm Road 92 in Silsbee; 2.3 miles west on Texas Highway 327 to the intersection with county road; 1 mile north on county road to the intersection with county road; 1.3 miles west on county road; 0.6 mile south and east; 300 feet south in woodland. (Latitude 30N, 21, 46; Longitude 94W, 13, 54)
RANGE IN CHARACTERISTICS: The solum thickness is more than 80 inches. Weighted average clay content in the particle-size control section ranges from 5 to 7 percent and sand content ranges from 80 to 90 percent. The texture is sand or loamy sand. Reaction ranges from extremely acid to strongly acid.
The A horizon has hue of 10YR, value of 3 to 5, and chroma of 2 or 3. Pedons with color value of 3 and chroma of 2 or 3 are less than 10 inches thick.
The Bw horizons have hue of 5YR or 7.5YR , value of 4 to 6, and chroma of 4 to 8. It has few to common iron stains on sand grains in shades of yellow or brown. Albic material in shades of gray or white is few to common and along root channels and prism faces.
GEOGRAPHIC SETTING: Turkey soils are on level to gently sloping terraces of streams and rivers. Slopes are 0 to 3 percent. These soils formed in sandy sediments of the Deweyville Formation of late Pleistocene age. Mean annual precipitation is 48 to 56 inches. Mean annual temperature is 67 to 69 degrees F. Frost free days range from 240 to 270 days. Elevation is 50 to 100 feet. The Thornthwaite P-E index is 68 to 80.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Belrose, Babco, McNeely, Tyden, and Votaw soils. Belrose, Babco and Tyden soils have a argillic horizon and are on lower landscape positions. McNeely soils have less than 5 percent clay in the particle-size control section and are on higher landscape positions. Votaw soils have aquic conditions for some time in most years and are on lower landscape positions.
DRAINAGE AND PERMEABILITY: Turkey soils are somewhat excessively drained. Runoff is negligible. Permeability is moderately rapid.
USE AND VEGETATION: Used primarily for timber production and wildlife habitat. Native vegetation is longleaf pine, sandjack and blackjack oak, sweetgum, yaupon, highbush blueberry, andropogons, panicums, and threeawns.
DISTRIBUTION AND EXTENT: The Western Gulf Coast Flatwoods (MLRA 152B) of southeast Texas. The series is of small extent.
MLRA OFFICE RESPONSIBLE: Temple, Texas
SERIES ESTABLISHED: Hardin County, Texas; 1998.
