LOCATION BLOOMINGDALE TNEstablished Series
The Bloomingdale series consists of very deep, poorly drained soils that formed in mixed alluvium from shales and limestone. They are on flood plains and in depressions in the Appalachian Ridges and Valleys. Slopes range from 0 to 2 percent.
TAXONOMIC CLASS: Fine, mixed, semiactive, nonacid, thermic Fluvaquentic Endoaquepts
TYPICAL PEDON: Bloomingdale silty clay loam--cultivated. (Colors are for moist soil)
Ap--0 to 5 inches; brown (10YR 4/3) silty clay loam; weak fine subangular blocky structure; friable; common fine roots; few irregularly shaped iron concretions and stains; many fine faint grayish brown (10YR 5/2) redoximorphic iron depletions; neutral; clear smooth boundary. (4 to 9 inches thick)
Bg--5 to 17 inches; gray (10YR 5/1) silty clay loam; weak coarse subangular blocky structure; friable; common fine roots; common fine tubular pores; many irregularly shaped iron concretions and stains; many medium faint yellowish brown (10YR 5/8) redoximorphic iron accumulations; slightly acid; gradual wavy boundary. (10 to 24 inches thick)
Cg1--17 to 25 inches; gray (10YR 6/1) silty clay; massive; friable; common fine roots; few fine tubular pores; many medium distinct strong brown (7.5YR 5/8) redoximorphic iron accumulations; slightly acid; gradual smooth boundary.
Cg2--25 to 37 inches; gray (10YR 6/1) silty clay; massive; friable; few fine and common very fine roots; common fine and few medium tubular pores; common fine faint pale brown (10YR 6/3) and many medium distinct strong brown (7.5YR 5/8) redoximorphic iron accumulations; neutral; gradual smooth boundary.
Cg3--37 to 60 inches; gray (10YR 6/1) silty clay; massive; friable; few very fine roots; common coarse distinct strong brown (7.5YR 5/8) redoximorphic iron accumulations; neutral.
TYPE LOCATION: Sullivan County, Tennessee. On Highway 11W, from intersection of Ollis Bowers Hill Road, 3400 feet west and 125 feet north in field. Latitude: 36 degrees, 34 minutes, 24 seconds north. Longitude: 82 degrees, 26 minutes, 6 seconds west.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 14 to 40 inches. Depth to bedrock is greater than 60 inches. Rock fragments, mostly rounded pebbles, range from 0 to 5 percent in the upper 40 inches and up to 20 percent below 40 inches. Reaction ranges from moderately acid to moderately alkaline.
The Ap horizon has hue of 10YR to 2.5Y, value of 4 or 5 and chroma of 2 to 4. Mottles and redoximorphic features are in shades of gray or brown. Texture is commonly silty clay loam but ranges to include loam and silt loam.
The Bg horizon has hue of 10YR to 5Y or neutral, value of 5 or 6, and chroma of 0 to 2. Mottles and redoximorphic features are in shades of gray ,brown, or red and range from few to many. Texture is silty clay loam, silty clay or clay.
The Cg horizon has hue of 10YR to 5Y, or neutral, value of 5 to 7, and chroma of 0 to 2. Mottles and redoximorphic features are in shades of gray, brown and red and range from few to many. Texture is commonly silty clay but ranges to include silty clay loam or clay. Below 40 inches texture may include their gravelly analogues.
COMPETING SERIES: There are no other series in this family. Similar soils in other families include the Lee, Melvin, and Newark series. Lee soils are strongly acid, have siliceous mineralogy, and are in a fine-loamy family. Melvin and Newark soils are in a fine-silty family and have soil temperatures less than 59 degrees F. In addition, Newark soils are somewhat poorly drained.
GEOGRAPHIC SETTING: Bloomingdale soils are on nearly level flood plains, and in depressions. They also occur occasionally in small upland depressions. Many areas are subject to ponding. Slopes are 0 to 2 percent. These soils formed in mixed alluvium from shales and limestone. The mean annual air temperature is 62 degrees F., and mean annual precipitation is 44 inches near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bays, Bellamy, Steadman and Pettyjon soils. Bays soils, on adjacent uplands, are less than 20 inches deep to bedrock. Bellamy soils, on adjacent terraces, are moderately well drained and have a brittle layer in the subsoil. Steadman soils, on slightly higher elevations, are moderately well drained. Pettyjon soils, on flood plains, are well drained.
DRAINAGE AND PERMEABILITY: Poorly drained; very slow runoff; slow permeability.
USE AND VEGETATION: Most areas of this soil are cleared. It is used for hay, pasture, and where drained for row crops. Wooded areas consist of American sycamore, water oaks, sweetgum and willows.
DISTRIBUTION AND EXTENT: The Southern Appalachian Ridges and Valleys (MLRA 128)of Tennessee and possibly Georgia and Alabama. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Sullivan County, Tennessee; 1991.
REMARKS: These soils were formerly included in the Melvin, Guthrie, Prader, and Purdy series. The classification was changed from fine-silty to fine based on lab data.
Diagnostic horizons recognized in this pedon are:
Ochric epipedon - 0 to 5 inches (Ap horizon),
Cambic horizon - 5 to 17 inches (Bg horizon),
Redoximorphic features: iron depletions and accumulations in each horizon, created by oxidation and/or reduction of iron during saturation of the soil with water.
