TYPE LOCATION: Hardin County, Texas; from the intersection of Farm Road 92 and Texas Highway 327 in Silsbee; 3.0 miles west on Texas Highway 327 to the intersection with county road; 0.4 mile south on county road; 30 feet north in woodland. (Latitude 30N, 20, 37; Longitude 94W, 14, 44)
RANGE IN CHARACTERISTICS: Solum thickness is more than 80 inches. The weighted average clay content of the particle-size control section ranges from 1 to 5 percent, and the sand content of the particle-size control section ranges from 90 to 95 percent. Texture is sand or loamy sand. Reaction is very strongly acid or strongly acid.
The A horizon has hue of 10YR, value of 3 to 6, and chroma of 2 to 4. Areas with value of 3 and chroma of 2 or 3 are less than 10 inches thick.
The Bw horizons have hue of 10YR, value of 5 to 7, and chroma of 3 to 6. It has few masses of albic material in hue of 10YR, value of 7 or 8, and chroma of 1 or 2 in root channels and in pores.
The E horizons have hue of 10YR, value of 7 or 8, and chroma of 2 to 4. It has few masses of iron accumulation on sand grains in shades of brown or yellow, and few masses of albic material in hue of 10YR, value of 7 or 8, and chroma of 1 or 2 in root channels and in pores.
The B'w horizon has hue of 7.5YR and 10YR, value of 5 to 7, and chroma of 4 to 6. It has few to common masses of iron accumulation in shades of red, brown, and yellow on sand grains, and few lamellae less than 1 centimeter thick.
COMPETING SERIES: These include the Alaga, Bigbee, Cainhoy, Darden, Foxworth, Glentosh, Lakeland, Tonkawa, Turkey, and Wando series in the same family. Alaga soils have 10 to 25 percent silt plus sand in the particle size control section. Bigbee soils have a water table at 20 to 40 inches for short periods and are subject to flooding. Cainhoy soils are formed in sandy marine sediments and have a Bh horizon greater than 80 inches. Darden soils have 10 to 25 percent silt and clay in the control section. Foxworth soils have a fluctuating seasonal high water table. Glentosh soils have a mean annual precipitation less than 46 inches. Lakeland soils formed from aeolian materials and can be on steeper landscapes. Tonkawa soils occur in areas of mean annual precipitation ranging from 40 to 50 inches section. Turkey soils have more than 5 percent clay in the particle-size control section. Wando soils are well drained.
GEOGRAPHIC SETTING: McNeely soils are on level to gently sloping terraces of streams and rivers. Slopes are 1 to 5 percent. These soils are on the flatwoods east of the Trinity River. These soils formed in sandy sediments of the Deweyville Formation of late Pleistocene age. The climate is hot and humid in the summer and cool and moist in the winter. 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 ranges from 50 to 100 feet. Thornthwaite P-E index is 68 to 80.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Babco, Belrose, Turkey, and Tyden soils. Babco soils have spodic horizons and are on lower landscape positions. Belrose soils have argillic horizons and are on lower landscape positions. Turkey soils have hue redder than 10YR and are on slightly lower landscape positions. Tyden soils are very poorly drained and are on lower landscape positions.
DRAINAGE AND PERMEABILITY: McNeely soils are excessively drained. Runoff is negligible. Permeability is very rapid.
USE AND VEGETATION: These soils are used mainly for wildlife habitat. Some areas are in timber production. Native vegetation is sandjack and blackjack oak, longleaf pine, sweetgum, yaupon, highbush blueberry, bull nettle, horsemint, threeawns, panicums and bluestems.
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.
REMARKS: The McNeely soils were formerly included with the Tonkawa series. It is named for McNeely Creek.
