HAINESVILLE SERIES


The Hainesville series consists of very deep, somewhat excessively drained, rapidly permeable, sandy soils that formed in sandy alluvial sediments. These soils are on nearly level stream terraces. Slopes range from 0 to 2 percent.

Bt&E--70 to 80 inches; yellow (10YR 7/6) fine sand; common fine distinct yellowish red (5YR 4/6) iron concentrations; single grain; very friable; common fine roots; common coarse pores; strong brown (7.5YR 5/8) discontinuous lamellae 0.2 to 2 cm thick make up combined thickness of 5 cm; common medium rounded iron-manganese concretions; about 1 percent quartzite pebbles; moderately acid. (Combined Bw/E, E/B and Bt&E horizons range from 40 to 70 inches thick)

TYPE LOCATION: Houston County, Texas; from the intersection of Loop 304 and Texas Highway 7 on west side of Crockett, 4.5 miles west on Texas Highway 7 to Farm Road 132, 4.5 miles southwest on Farm Road 132 to end of pavement, 2.0 miles west on county road to cattle guard, 0.3 mile west on private road, 0.25 mile south in cropland. (Longitude 95W 43 05, Latitude 31N 13 40).

Solum thickness: More than 80 inches
Clay content in the Control Section: 2 to 10 percent
Redoximorphic features: None
Other distinctive soil features: Lamellae are within a depth of 40 to 72 inches. These soils are dry in the moisture control section 60 to 90 cumulative days in most years.
Concentrated minerals: Rounded quartzite or ironstone pebbles range from very few to about 3 percent in most pedons.

A or Ap horizon:
Color--Hue of 7.5YR or 10YR, value of 3 to 6, and chroma of 3 or 4

Redoximorphic features--None
Texture--Fine sand or loamy fine sand
Other features--None

E/Bt or Bt/E horizon:

Reaction--Very strongly acid to slightly acid

COMPETING SERIES: These are the Alpin, Catpoint, and Duffern series in the same family. Soils in closely related families are the Bienville, Betis, Darden, Flo, Grapeland, and Tonkawa series. Alpin soils are dry in the moisture control section for less than 60 days in normal years. Catpoint soils contain more gravel in the solum and are dry in the moisture control section for less than 60 days in normal years. Duffern soils formed in Eocene Age sediments on uplands. Bienville, Betis, Flo, and Grapeland soils have an argillic horizon. Darden and Tonkawa soils do not have lamellae within a depth of 80 inches.

GEOGRAPHIC SETTING: Hainesville soils are on nearly level Pleistocene Age stream terraces with slopes of 0 to 2 percent. Areas are about 5 to 35 feet above present streams. Mean annual temperature ranges from 64 to 67 degrees F. Frost free days range from 235 to 275 and elevation ranges from 125 to 350 feet above sea level. The mean annual rainfall ranges from 40 to 46 inches and the Thornthwaite P-E index ranges from 64 to 70.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Austonio, Bernaldo, Derly, Freestone, Gallime, Mollville, and Portersprings series. Austonio, Bernaldo, Freestone, and Gallime soils are on slightly higher positions. These soils have a loamy argillic horizon. Derly and Mollville soils are on slightly lower positions. These soils have a loamy or clayey argillic horizon. Portersprings soils have a mollic epipedon and are on similar or slightly lower terrace positions.

DRAINAGE AND PERMEABILITY: Hainesville soils are somewhat excessively drained. Runoff is negligible and permeability is rapid. These soils typically do not have a water table within a depth of 6 feet; however, a flooded phase is recognized that is wet in the layers below 4 to 6 feet from mid fall through the spring months in normal years.

USE AND VEGETATION: Used mainly for pastureland or woodland. Some areas are cropped to corn or small grain and truck crops such as squash, cucumbers, and peppers. Pastures are mainly improved bermudagrass. Small grain is commonly used for grazing.

DISTRIBUTION AND EXTENT: East-central and north-east Texas. The series is moderately extensive.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Temple, Texas

SERIES ESTABLISHED: Wood County, Texas; 1992.

REMARKS: Hainesville soils were formerly included with the Bienville series. The name is from a small community in Wood County. The series was updated in 2002 to allow very stronly acid reaction in the A horizon and value 5 matrix color in the E horizon based on documentation collected in Shelby County, Texas. The series was updated in 2004 to clarify that a water table is typically not present within a depth of 6 feet, except in the flooded phase which was correlated in Vernon Parish, Louisiana.

Diagnostic horizons and features recognized in this pedon:

Ochric epipedon - 0 to 14 inches (Ap and A horizons).

Lamellae - 58 to 80 inches (Bw/E3 and Bt&E horizons).
