LOCATION WADLEY FL+AL MS
Rev. ACT, AGH
The Wadley series consists of very deep, well drained and somewhat excessively drained soils that formed in sandy and loamy marine sediments. They are on sandy uplands on the North Central Florida Ridge and the Atlantic Coast Flatwoods. Permeability is rapid in the A and E horizons and moderate in the Bt horizon. Slopes range from 0 to 40 percent.
TAXONOMIC CLASS: Loamy, siliceous, subactive, thermic Grossarenic Paleudults
TYPICAL PEDON: Wadley fine sand, on a 1 percent slope, in a wooded area. (Colors are for moist soil.)
A--0 to 2 inches; light brownish gray (10YR 6/2, rubbed) fine sand; single grained; loose; common fine and very fine roots; moderately acid; clear smooth boundary. (2 to 9 inches thick)
E1--2 to 30 inches; very pale brown (10YR 7/3) fine sand; single grained; loose; common fine and medium roots, few coarse roots; common fine and medium faint light gray (10YR 7/1 & 7/2) pockets and streaks of uncoated sand grains; few sand size black charcoal fragments; strongly acid; diffuse wavy boundary.
E2--30 to 54 inches; very pale brown (10YR 7/4) fine sand; single grained; loose; common fine and medium roots; few coarse roots; common fine and medium faint yellow (10YR 7/6 mottles: few fine and medium faint very pale brown streaks of uncoated sand; strongly acid; diffuse wavy boundary. (total thickness of the E horizon is 50 to 77 inches)
E&Bt--54 to 72 inches; light gray (10YR 7/2) fine sand (E); common fine prominent yellowish brown (10YR 5/8) pockets and horizontal lamellae of loamy fine sand (Bt) 3 to 8 inches long and 1/8 to 1/4 inch thick; single grained; loose; few fine and medium roots; strongly acid; clear wavy boundary. (0 to 20 inches thick)
Bt--72 to 80 inches; yellowish brown (10YR 5/8) fine sandy loam; weak medium subangular blocky structure; very friable; few fine and very fine roots; few fine prominent very pale brown (10YR 7/3) streaks of uncoated sand; few coarse krotovina with color and texture similar to that of the E&Bt horizon; very strongly acid. (4 to more than 20 inches thick)
TYPE LOCATION: Dixie County, Florida; approximately 500 feet east and 600 feet south of the northwest corner of Sec. 31, R. 14 E., T. 10 S.
RANGE IN CHARACTERISTICS: Solum thickness is more than 70 inches. Soil reaction ranges from very strongly acid to moderately acid throughout, except where limed. Calcium content is less than 1 meq per 100 grams of soil
The A horizon has hue of 10YR, value of 3 to 6, and chroma of 2 to 4. Texture is sand, fine sand, loamy sand, or loamy fine sand.
The E horizon has hue of 7.5YR to 2.5Y, value of 5 to 8, and chroma of 3 to 6. Texture is sand, fine sand, loamy sand, or loamy fine sand.
The (E) part of the E&Bt horizon, where present, has hue of 10YR, value of 5 to 8, and chroma of 2 to 6. Texture is sand or fine sand. The (Bt) part is discontinuous horizontal lamellae, with hue of 7.5YR to 10YR, value of 5 to 7 and chroma of 4 to 8. Texture is coated sand to loamy fine sand.
In some pedons a Bw horizon is present. It has hue of 5YR to 10YR, value of 5 to 8, and chroma of 4 to 6. Texture is sand, fine sand, loamy sand, or loamy fine sand.
The Bt horizon has hue of 2.5YR to 10YR, value of 4 to 6, and chroma of 4 to 8, with or without mottles in shades of brown or yellow. Texture is sandy loam, fine sandy loam or sandy clay loam. Percent plinthite or gravel by volume within 60 inches of the surface is less than 5 percent.
COMPETING SERIES: These are
Tehran series in the same family, and the
Troup series. Albany, Blanton, Eddings, and Murad soils have a seasonal water table within a depth of 72 inches. Darco and Shankler soils are in areas of less than 50 inches of rainfall. Tehran soils have calcium carbonate content of more than 1 meg per 100 grams of soil. Troup soils have a kandic horizon.
GEOGRAPHIC SETTING: Wadley soils occur on nearly level to steep, sandy uplands on the coastal plain of northern peninsular Florida. Slopes are 0 to 40 percent. They formed in sandy and loamy marine sediments. The mean annual temperature is 66 to 70 degrees F., and average annual precipitation is 50 to 60 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing
Blanton series, and the
Penney series. The associated soils are on about the same landscape position. Alaga, Alpin, Kershaw, Lakeland, Ortega, and Penney soils are sandy to a depth of greater than 80 inches. In addition, Ortega soils have a seasonal high water table within a depth of 72 inches. Bonneau and
Lucy soils have a loamy argillic horizon within a depth of 40 inches. Eustis soils have a sandy argillic horizon.
DRAINAGE AND PERMEABILITY: Wadley soils are well or somewhat excessively drained. The water table is below a depth of 72 inches throughout the year during most years. Permeability is rapid in the A and E horizons and moderate in the Bt horizon.
USE AND VEGETATION: Most areas have been planted to pine or are in pasture. Some small areas are used for irrigated crops. Other areas remain in their natural vegetation or have been subdivided for residential development. Natural vegetation consists mainly of live oak, turkey oak, bluejack oak, chapman oak, and longleaf pine in the overstory, and pineland threeawn, lopsided indiangrass, bluestems, panicums, scattered saw palmetto, blackberry, running oak, reindeer moss and other forbs in the understory.
DISTRIBUTION AND EXTENT: Northern Peninsular Florida. The series is of small extent. It is probable that Wadley soils will be used in west Alabama, Louisiana, and Mississippi.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama
SERIES ESTABLISHED: Gilchrist County, Florida, 1991, by amendment to the correlation.
REMARKS: The Troup series was originally correlated in Gilchrist County, Florida, but for sake of better join was changed to Wadley after the series was proposed in adjacent Dixie County.
Diagnostic horizons recognized in this pedon include:
Ochric epipedon: the zone from the surface to 72 inches. (A, E1, E2, E&Bt horizons)
Argillic horizon: the zone from 72 to 80 inches. (Bt horizon)
