(Combined thickness of the Bt horizons is 0 to 16 inches)
Btv1--33 to 57 inches; olive yellow (2.5Y 6/6) sandy clay loam; moderate medium subangular blocky structure; friable; few fine roots; sand grains coated and bridged with clay; few ironstone pebbles; about 5 percent, by volume, plinthite; many coarse prominent yellowish red (5YR 4/6) and many medium distinct yellowish brown (10YR 5/6) masses of iron accumulation; many coarse prominent light gray (10YR 7/1) iron depletions; very strongly acid; gradual smooth boundary. (16 to 28 inches thick)
Btv2--57 to 75 inches; reticulately mottled yellowish brown (10YR 5/6) brownish yellow (10YR 6/6) light gray (N 7/0) and red (2.5YR 4/8) sandy clay loam; weak medium subangular blocky structure; firm; few distinct patchy clay films on faces of peds; about 15 percent, by volume, plinthite; areas of brown and yellow are iron accumulation and areas of gray are iron depletions; very strongly acid.
TYPE LOCATION: Bulloch County, Georgia; approximately 5.0 miles southeast of Denmark on Georgia Highway 46 and about 900 feet north of highway.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 60 to more than 90 inches. Depth to horizons with 5 to 20 percent plinthite ranges from 30 to 60 inches. The upper 20 inches of the horizon ranges from 15 to 25 percent clay.
Reaction ranges from very strongly acid to strongly acid, except where the surface has been limed. Ironstone nodules, 2 to 15 mm in size, range from 0 to 5 percent, by volume.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 3 through 5, and chroma of 0 to 2. Texture is loamy fine sand, loamy sand, fine sand, or sand.
The E horizon has hue of 10YR through 5Y, value of 5 through 8 and chroma of 2 through 8. There are none to common masses of iron accumulation in shades of brown and yellow and iron depletions in shades of gray. Texture is loamy fine sand, loamy sand, fine sand or sand.
The BE horizon, where present, has hue of 10YR or 2.5Y, value of 6 or 7, and chroma of 3 through 8. Redoximorphic features in shades of brown, yellow, and gray range from none to common. Texture is loamy sand or sandy loam.
The Bt horizon has hue of 10YR or 2.5Y, value of 4 through 8, and chroma of 4 through 8. Redoximorphic features in shades of red, brown, yellow, and gray range from few to many. Texture is fine sandy loam, sandy loam or sandy clay loam.
The Btv horizon is commonly reticulately mottled with masses of iron accumulation in shades of red, brown, or yellow, and iron depletions in shades of gray. In some pedons, they have hue of 10YR or 2.5Y, value of 4 through 8, and chroma of 0 through 8. Masses of iron accumulation in shades of red, brown, or yellow, and iron depletions in shades of gray range from common to many. Texture is fine sandy loam, sandy loam or sandy clay loam.
COMPETING SERIES: There are no other known series in the same family.
GEOGRAPHIC SETTING: Leefield soils are on uplands of the Coastal Plain. They formed in deposits of sandy and loamy marine sediments. Slopes range from 0 to 12 percent. The average annual temperature ranges from 60 to 71 degrees F., and the average annual precipitation ranges from about 40 to 55 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the Ardilla, Chipley, Clarendon, Dothan, Fuquay, Lakeland, Ocilla, Robertsdale, and Stilson soils. Ardilla, Clarendon and Robertsdale soils do not have arenic epipedons. In addition, Clarendon soils are on slightly higher positions and are moderately well drained. Chipley and Lakeland soils are sandy throughout. In addition Lakeland soils are on higher positions and are excessively drained. Dothan and Fuquay soils are on higher positions and are well drained. In addition, Dothan soils have surface and subsurface horizons less than 20 inches thick. Ocilla soils have less than 5 percent plinthite in any horizon. The moderately well drained Stilson soils are on slightly higher positions.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained; rapid permeability in surface and subsurface layers and moderately slow permeability in lower part of subsoil.
USE AND VEGETATION: Much of this soil is used for cropland, pasture, or woodland. Forest vegetation consists of slash pine, longleaf pine, and loblolly pine plus occasional maple and sweetgum.
DISTRIBUTION AND EXTENT: Alabama, Florida, Georgia, and South Carolina. The series is of moderate extent.
MLRA OFFICE RESPONSIBLE: Auburn, Alabama.
SERIES ESTABLISHED: Appling-Jeff Davis Counties, Georgia; 1969.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon - the zone from the surface of the soil to a depth of approximately 23 inches. (Ap and E horizons)
Argillic horizon - the zone from approximately 23 to 75 inches. (Bt1, Bt2, Btv1 and Btv2 horizons)
Plinthic feature - the zone with 5 percent or more plinthic from approximately 33 to 75 inches. (Btv1 and Btv2 horizons)
