DALEVILLE SERIES
The Daleville series consists of poorly drained soils that formed in loamy marine or fluvial sediment. Permeability is slow. These nearly level soils are on uplands and terraces of the Southern Coastal Plain. They are saturated late in winter and early in spring. Water runs off the surface very slowly. Slopes range from 0 to 2 percent.
TAXONOMIC CLASS: Fine-loamy, siliceous, active, thermic Typic Paleaquults
TYPICAL PEDON: Daleville loam--pasture (Colors are for moist soil unless otherwise stated.)
Ap--0 to 6 inches; dark grayish brown (10YR 4/2) loam; weak fine granular structure; friable; many fine and medium roots; many medium distinct dark yellowish brown (10YR 4/4) masses of iron accumulation; slightly acid; clear smooth boundary. (2 to 8 inches thick)
E--6 to 16 inches; light brownish gray (10YR 6/2) loam; weak coarse prismatic structure parting to weak fine and medium subangular blocky; friable; few fine roots; many medium distinct yellowish brown (10YR 5/6) masses of iron accumulation; slightly acid; clear irregular boundary. (2 to 12 inches thick)
Btg1--16 to 24 inches; gray (10YR 6/1) loam; moderate medium prismatic structure parting to moderate medium subangular blocky; firm, plastic; few fine roots; few tongues of gray silt between prisms; few patchy clay films on faces of peds; many medium distinct yellowish brown (10YR 5/6) masses of iron accumulation; strongly acid; clear irregular boundary.
Btg2--24 to 40 inches; gray (10YR 5/1) clay loam; moderate coarse prismatic structure parting to moderate medium subangular blocky; firm, plastic; few fine roots; few tongues of gray (10YR 6/1) silt between prisms; few patchy clay films on faces of peds; many medium distinct strong brown (7.5YR 5/8) masses of iron accumulation; very strongly acid; gradual wavy boundary.
Btg3--40 to 55 inches; gray (10YR 5/1) clay loam; weak coarse prismatic structure parting to moderate medium subangular blocky; firm, plastic; few seams of gray silt loam between prisms, few patchy clay films on faces of peds; many medium distinct strong brown (7.5YR 5/6) and few fine distinct yellowish brown masses of iron accumulation; very strongly acid; gradual wavy boundary.
Btg4--55 to 70 inches; gray (10YR 6/1) clay loam; weak medium subangular blocky structure; firm, plastic; few faint clay films on faces of peds; few medium prominent red (2.5YR 5/6) and common medium distinct strong brown (7.5YR 5/6) and yellowish brown (10YR 5/6) masses of iron accumulation; very strongly acid. (Combined thickness of the Btg subhorizons is 40 to 60 inches or more.)
TYPE LOCATION: Lauderdale County, Mississippi. Approximately 0.5 mile east of junction of State Highway 39 and Navy Base Road, 0.2 mile south of road into pasture. SW1/4, SE1/4 Sec. 15, T. 8 N., R. 16 E.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 60 to more than 80 inches. Reaction is very strongly acid or strongly acid, except the surface layers in areas that have been limed.
The A horizon has hue of 10YR or 2.5Y, value of 3 to 5, and chroma of 1 or 2. Texture is fine sandy loam, loam, sandy loam, or silt loam.
The E horizon, if present, has hue of 10YR or 2.5Y, value of 5 to 7, and chroma 1 or 2. It is fine sandy loam, loam, sandy loam, or silt loam.
The Btg horizon has hue of 10YR or 2.5Y, value of 4 to 7, and chroma of 1 or 2. Mottles are few to many in shades of brown, red, or yellow. In some pedons the lower part of the Bt horizon is mottled in shades of gray, red, or brown. The upper 20 inches of the B horizon has 20 to 35 percent clay and more than 30 percent silt. Black and brown concretions, if present, are few to many. Texture is loam, sandy clay loam, silty clay loam, or clay loam.
COMPETING SERIES: These are
Rains in the same family and the
Bethera,
Coxville,
Grantham,
Leaf,
Myatt,
Smithton,
Trebloc, and
Woodington series. Bethera, Coxville, and Leaf soils have a clayey control section. Grantham and Trebloc soils have a fine-silty control section. Myatt soils have a solum less than 60 inches thick. Rains soils have less than 30 percent silt in the control section. Smithton and Woodington soils have a coarse-loamy control section.
GEOGRAPHIC SETTING: Daleville soils are on uplands and terraces of the Southern Coastal Plain. These are nearly level soils that formed in loamy sediment. Slopes range from 0 to 2 percent. The climate is warm and humid. Mean annual precipitation is about 52 inches. Mean annual temperature is about 64 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing
Leaf,
Myatt,
Smithton, and
Trebloc series, and the
Kinston,
Mashulaville,
Quitman,
Savannah, and
Stough series. Myatt, Leaf, Smithton, and Trebloc soils are on similar landscapes. Kinston soils do not have an argillic horizon and are on flood plains. Mashulaville soils are on similar landscapes but have a fragipan. Quitman, Savannah, and Stough soils, which are on slightly higher ridges, are better drained; also, Savannah soils have a fragipan.
DRAINAGE AND PERMEABILITY: Daleville soils are poorly drained. Runoff is very slow, and permeability is slow. The water table fluctuates between the surface and a depth of 1.0 foot late in winter and early in spring. Most areas of this soil are flooded for brief periods, unless protected.
USE AND VEGETATION: These soils mainly are in forests of water oak, willow oak, maple, sweetgum, ash, cypress, and loblolly pine. Some areas are cleared and used for growing soybeans, pasture, and hay.
DISTRIBUTION AND EXTENT: Southern Coastal Plain in Mississippi and South Carolina. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Auburn, Alabama
SERIES ESTABLISHED: Lauderdale County, Mississippi; 1980.
REMARKS: Diagnostic horizons and features recognized in this pedon:
Ochric epipedon - the zone from the surface to 16 inches (Ap & E).
Argillic horizon - the zone from approximately 16 to 70 inches (Btg1, Btg2, Btg3, and Btg4 horizons).
Aquic feature: Does not have a horizon that has dominant chroma of 3 or more within 75 cm of the surface.
ADDITIONAL DATA: Laboratory data for three pedons were obtained from the Soil Genesis and Morphology Laboratory of the Mississippi Agricultural and Forestry Experiment Station, Mississippi State, Mississippi.
