(Combined thickness of the Bt horizon ranges from 50 to more than 75 inches.)
TYPE LOCATION: Meigs County, Tennessee; on River Road; 4 miles north of Decatur; 1.3 miles north of Eaves Ferry Road; on west-facing wooded slope; 150 feet east of a two-pronged chestnut oak tree which is 40 feet west of River Road.
RANGE IN CHARACTERISTICS: Solum thickness and depth to bedrock is greater than 60 inches. Rock fragments are mostly gravel and cobbles of chert and range from 10 to 45 percent in individual horizons but the particle size control section averages between 15 and 35 percent. Some pedons have more than 45 percent below 40 inches. Reaction is strongly acid or very strongly acid except where limed.
The A or Ap horizon has hue of 7.5YR or 10YR value of 3 to 6 and chroma of 2 to 4. In severely eroded areas, some Ap horizons have a hue of 5YR. Texture of the fine-earth is silt loam, loam, or fine sandy loam. Moderately eroded and severely eroded areas may be silty clay loam or clay loam.
The E horizon, if present, has a hue of 7.5YR or 10YR, value of 5 or 6 and chroma of 2 to 4. Texture of the fine-earth fraction is silt loam, loam, or fine sandy loam.
The BE horizon, if present, has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 4 to 6. Texture of the fine-earth fraction is silt loam, loam, or fine sandy loam.
The Bt horizon has hue of 2.5YR to 5YR, value of 4 or 5 and chroma of 4 to 8. The upper part may have hue of 7.5YR. Mottles are in shades of brown, yellow, or red. Texture of the fine-earth fraction is silty clay or clay except the upper part ranges to silty clay loam or clay loam.
COMPETING SERIES: These are Dewey, Henderson, Lugoff, Marlboro, Summerton and Waynesboro series. Dewey soils have less than 15 percent rock fragments in the particle size control section. Marlboro and Summerton soils lack fragments of chert. Henderson soils have 7.5YR and 10YR hues in the subsoil. Lugoff soils have fragments of quartz in the argillic horizon. Waynesboro soils have more than 20 percent sand content and formed in old alluvium.
GEOGRAPHIC SETTING: Fullerton soils are on gently sloping to very steep uplands. Slopes range from 2 to 70 percent. The soil formed in residuum from cherty limestone or dolomite. These soils are in areas that have 45 to 55 inches average annual precipitation and average annual air temperatures of about 60 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bodine, Dewey, Minvale, Dickson, and Mountview series and the competing Dewey series. Bodine and Dewey soils are on adjacent upper side slopes and ridges. Bodine soils are in a loamy-skeletal particle-size family. Minvale soils are on foot slopes and benches and are in a fine-loamy particle size family. Mountview soils are on similar positions, are in the fine-silty particle-size family, and have less than 15 percent rock fragments. Dickson soils are on slightly lower lying, smoother or concave positions and have a fragipan.
DRAINAGE AND PERMEABILITY: Fullerton soils are well drained. Runoff is medium and permeability is moderate.
USE AND VEGETATION: About two-thirds of the acreage is cleared. Pasture is the main use. Small patches of corn, cotton, tobacco, small grains, and hay are grown. Native vegetation is forests of oaks, hickory, elm, yellow-poplar, dogwood, and beech.
DISTRIBUTION AND EXTENT: The Southern Appalachian Ridges and Valleys in Alabama, northwest Georgia, and east Tennessee, and the Highland Rim and Pennyroyal in south-central Tennessee and Alabama. The series is of large extent.
