LOCATION WINGINA VAInactive Series
TAXONOMIC CLASS: Fine-loamy, mixed, active, thermic Fluventic Hapludolls
TYPICAL PEDON: Wingina loam-on a 1 percent slope-in a pasture. (Colors are for moist soil unless otherwise stated)
Ap=0 to 14 inches; very dark grayish brown (10YR 3/2) broken, dark brown (10YR 3/3) crushed, loam; brown (10YR 5/3) dry; moderate medium granular structure; friable, slightly sticky, slightly plastic; few fine and medium roots; common fine flakes of mica; neutral; abrupt smooth boundary. (Ap and A horizons are 10 to 24 inches thick)
Bw1=14 to 40 inches; brown (10YR 4/3) loam; weak coarse subangular blocky structure; friable, slightly sticky, slightly plastic; few fine and medium roots; common fine flakes of mica; neutral.
Bw2=40 to 72 inches; brown (10YR 4/3) loam; weak coarse subangular blocky structure; friable, slightly sticky, slightly plastic; common fine flakes of mica; neutral. (Combined thickness of the Bw horizon is 20 to 60 inches or more)
TYPE LOCATION: Appomattox County, Virginia; 2.1 miles northwest 315 degrees of the junction of Highways VA-611 and VA-667 and 2.9 miles north 0 degrees of the junction of Highways VA-611 and VA-721. (37o28'21.8" latitude, 78o58'3.5" longitude)
RANGE IN CHARACTERISTICS: Solum thickness ranges from 30 to 60 inches or more. Depth to bedrock is more than 60 inches. Gravel and cobble size rock fragments commonly range from 0 to 15 percent throughout the soil, but some pedons range up to 80 percent in the C horizon below 40 inches. Reaction is strongly acid through neutral.
The Ap and A horizons have hue of 10YR; value moist of 3, value dry of 4 or 5; and chroma of 2 or 3. They are sandy loam, fine sandy loam, loam, or silt loam.
The Bw horizon has hue of 7.5YR or 10YR, value of 3 through 5, and chroma of 3 or 4. Mottles in shades of yellow, brown, or red are in some pedons. Mottles in shades of gray are in some pedons below a depth of 24 inches. The Bw horizon is fine sandy loam, sandy loam, loam, silt loam, sandy clay loam, clay loam, or silty clay loam. Silt loam and silty clay loam are limited to individual subhorizons in some pedons.
The C horizon, where present, has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 3 through 8. Mottles in shades of yellow, brown, red, or gray are in some pedons. The C horizon is sand, loamy sand, fine sandy loam, or sandy loam. The C horizon in some pedons is stratified.
COMPETING SERIES: There are no known series in the same family.
GEOGRAPHIC SETTING: Wingina soils are on nearly level flood plains of the Piedmont Plateau. Slopes range from 0 to 5 percent. They formed in recent alluvium derived from limestones, sandstones, siltstones, phyllites, shales, gneiss, granites, schists, and greenstones. The mean annual temperature ranges from 57 to 62 degrees F. Annual precipitation ranges from 35 to 45 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Batteau (tentative), Chewacla, Galtsmill (tentative), Riverview, Toccoa, Wehadkee, and Yogaville (tentative) soils. These soils are on flood plains. Batteau, Wehadkee and Yogaville soils have gray mottles within 20 inches of the soil surface. Chewacla, Riverview, Toccoa, and Wehadkee soils do not have thick dark surface layers. Galtsmill soils have less clay in the subsoil.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is slow. Permeability is moderate. Subject to flooding.
USE AND VEGETATION: These soils are used primarily for hay, cropland, or pasture.
DISTRIBUTION AND EXTENT: Flood plains within the Piedmont Plateau in Virginia, mainly along the major rivers that have headwaters in the Southern Appalachian Ridge and Valley. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Raleigh, North Carolina
SERIES PROPOSED: Appomattox County, Virginia, 1992.
REMARKS: This soil has been previously mapped as Congaree, Riverview, Starr, Suches, and Tuckahoe soils.
Diagnostic horizons and features recognized in this pedon are:
1. Mollic epipedon-the zone from the surface to 14 inches (Ap horizon) 2. Cambic horizon-the zone from 14 inches to 72 inches (Bw horizon)
