Bb--34 to 56 inches; yellowish brown (10YR 5/4) silt loam, few medium distinct pale brown (10YR 6/3) light brownish gray (10YR 6/2), and dark brown (10YR 3/3) mottles; weak medium subangular blocky structure; friable; 15 percent by volume fragments of chert up to 3 inches in size; strongly acid.
TYPE LOCATION: Hancock County, Tennessee; 0.5 mile northeast of Stony Gap Baptist Church; 40 feet north of graveled road.
RANGE IN CHARACTERISTICS: Thickness of the solum ranges from about 25 to 60 inches. Depth to bedrock ranges from 5 to 15 feet. Reaction is medium acid or strongly acid except the surface layer is less acid where limed. Many of these soils contain coarse fragments of chert, gravel, or cobblestone with the content in each horizon ranging from about 5 to about 30 percent by volume.
The A horizon is brown (10YR 4/3, 5/3) or dark grayish brown (10YR 4/2). It is silt loam, loam, or rarely sandy loam. In a few places, the surface layer is recent overwash of yellowish red or strong brown silty clay loam.
The B horizon is dark yellowish brown (10YR 4/4), yellowish brown (10YR 5/4, 5/6), or brown (10YR 4/3; 7.5YR 4/4). Texture of the B horizon is most commonly silt loam or loam, and rarely silty clay loam or clay loam. The 10- to 40-inch control section centers on 25 percent clay content and ranges from 18 to 32 percent clay, and sand coarser than very fine sand ranges from about 10 to 45 percent.
The A1b horizon is at depths ranging from 20 to 40 inches and is lacking in some pedons. It is dark brown (10YR 3/3) or very dark grayish brown (10YR 3/2). Texture is silt loam or loam.
The Bb horizon has dominant color of yellowish brown (10YR 5/4, 5/6), strong brown (7.5YR 5/6), brown (7.5YR 4/4), or dark yellowish brown (10YR 4/4) with few to many mottles in shades of brown, yellow, red, and gray or is mottled gray, yellow, and brown and lacks dominant color. It is silt loam, loam, silty clay loam, or clay loam. This horizon is dominantly a cambic horizon, but in a few pedons it has enough clay films and increase clay content to qualify for an argillic horizon. In a few other pedons, it lacks both structure and any evidence of illuviation.
COMPETING SERIES: These are the Bermudian, Comus, Emory, Ennis, Hadley, Ondawa, and Pope series. Bermudian soils have mixed mineralogy. Comus, Ondawa, and Pope soils also have mixed mineralogy and, in addition, have less than 18 percent clay content in the 10- to 40-inch control section. Emory soils have dark brown or dark reddish brown A horizons and less than 15 percent sand and coarse fragments in the 10- to 40-inch control section. Ennis soils have soil temperatures more than 59 degrees F. Hadley soils have less than 18 percent clay content and less than 15 percent sand content in the 10- to 40-inch control section, and have mixed mineralogy.
GEOGRAPHIC SETTING: Greendale soils are on bottomlands, in narrow strips along drainageways, and in depressions. Slopes range from 0 to 6 percent. The soil formed in local alluvium washed from soils derived from limestone, shale, and sandstone. Near the type location average annual temperature is 54.7 degrees F., and average annual precipitation is 50.2 inches. Some areas flood occasionally for very brief duration.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dunmore, Fullerton, Landisburg, and Lindside series. Dunmore and Fullerton soils are on adjacent upland slopes and have a clayey argillic horizon. Landisburg soils are on adjacent footslopes and have a fragipan. Lindside soils are on slightly lower lying bottomlands and have gray mottles within 20 inches of the surface.
DRAINAGE AND PERMEABILITY: Greendale soils are well drained. Runoff is slow and permeability is moderate.
USE AND VEGETATION: Most areas are cleared and used for growing corn, tobacco, vegetable crops, small grains, hay, and pasture. The native vegetation was mixed hardwoods.
DISTRIBUTION AND EXTENT: The Great Appalachian Valley in Tennessee and Oklahoma. The series is of moderate extent.
MLRA OFFICE RESPONSIBLE: Lexington, Kentucky
SERIES ESTABLISHED: Washington County, Virginia; 1937.
REMARKS: The Greendale series was classified in the Gray Brown Podzolic great soil group intergrading to the Alluvial great soil group.
