LOCATION NORENE TNEstablished Series
TAXONOMIC CLASS: Fine-silty, mixed, active, thermic Typic Epiaqualfs
TYPICAL PEDON: Norene silt loam-pasture. (Colors are for moist soil)
Ap--0 to 9 inches; grayish brown (10YR 5/2) silt loam; common fine distinct brown (7.5YR 4/4) mottles; weak fine granular structure; very friable; many fine roots and common medium roots; few fine pores; medium acid; clear smooth boundary (6 to 10 inches thick).
AB--9 to 15 inches; dark grayish brown (10YR 4/2) silt loam; common distinct brown (7/5YR 4/4) coatings on faces of peds; weak medium subangular blocky and weak fine granular structure; very friable; many fine roots; few fine pores; many fine black concretions; medium acid; gradual smooth boundary (0 to 7 inches thick).
Btg1--15 to 32 inches; gray (10YR 5/1) silty clay loam; many medium prominent dark yellowish brown (10YR 4/6) mottles; moderate medium subangular blocky structure; very friable; common fine roots; few fine pores; few faint clay films on faces of peds and in pores; medium acid; clear wavy boundary.
Btg2--32 to 42 inches; gray (10YR 5/1) silty clay loam; many medium prominent dark yellowish brown (10YR 4/6) mottles; weak fine and medium subangular blocky structure; firm; few fine roots; few fine pores; few faint clay films on faces of peds and in pores; medium acid; clear wavy boundary. (Combined thickness of the Btg horizon ranges from 15 to 35 inches.)
Cg--42 to 60 inches; gray (10YR 5/1) silty clay; many fine prominent strong brown (7.5YR 5/8) mottles; massive, firm; few fine roots; medium acid.
TYPE LOCATION: Wilson County, Tennessee; from Lebanon west on U.S. Highway 70 about 6.5 miles, north on Cairo Bend Road to Smith Road, 1 mile west on Smith Road, 50 feet northwest of the road and 500 feet southwest of Dry Fork Branch.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 30 to 60 inches or more. Depth to bedrock is more than 5 feet. The soil ranges from strongly acid to neutral. Coarse fragments make up less than 5 percent of the soil.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 4 or 5 and chroma of 2 or 3. Mottles are none to common in shades of brown or gray. It silt loam or silty clay loam.
Most pedons have a transitional horizon between the A and Bt horizons. In pedons without a transitional horizon, the upper part of the Bt horizon must meet the color requirements of an Aeric Orchraqualfs.
The Btg horizon has hue of 10YR or 2.5Y, value of 4 to 7 and chroma of 1 or 2 or is neutral. Mottles are in shades of brown, red, and gray. In addition to these colors, some pedons have coatings on peds with a chroma of 2 or less and a matrix of higher chroma with mottles of chroma 2 or less. It is silt loam or silty clay loam.
The BC and Cg horizons have hue of 10YR or 2.5Y, value of 4 to 7 and chroma of 1 or 2 or is neutral. Mottles are in shades of brown or gray and some pedons may be mottled without a dominant matrix color. It is silt loam, loam, silty clay loam, silty clay or clay.
COMPETING SERIES: These are the Acy, Dundee, Essen, Frozard, Galvez, Herbert, Idee, McGehee and Patoutville series in the same family. Acy soils have calcium carbonate concretions in the B horizon. Dundee soils formed is stratified loamy sediments and have a higher sand content. Essen, Glavez and Patoutville soils are moderately alkaline in the lower part of the B horizon. Frozard soils are neutral to strongly alkaline in the Bt horizon and have 5 to 15 percent exchangeable sodium in the upper 16 inches of the Bt. Hebert and McGehee soils have hue of 5YR or 7.5YR in the B horizon. Idee soils have sola thicker than 60 inches and have a 2Bt horizon.
GEOGRAPHIC SETTING: Norene soils are on nearly level stream terraces and on broad flats and in slight depressions at the heads of drainageways. These soils formed in alluvium that is silty in the upper part and typically becomes more clayey with depth. Slopes are normally less than 1 percent, but range from 0 to 2 percent. The average annual precipitation is about 52 inches near the type location.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Agee, Capshaw and Woodmont soils on similar positions and Lindell soils on adjacent flood plains. Agee and Capshaw soils have a clayey control section and Agee soils have a mollic epipedon. Woodmont soils have a fragipan. Lindell soils have a cambic horizon and are moderately well drained.
DRAINAGE AND PERMEABILITY: Poorly drained or somewhat poorly drained; moderately slow permeability; runoff is very slow to ponded. These soils are rarely or occasionally flooded for brief periods.
USE AND VEGETATION: Most areas of this soil are used for pasture or as woodland. Native vegetation is water-tolerant hardwoods such as water oak, willow oak, American elm, sycamore, hackberry, red maple, sweetgum and eastern cottonwood.
DISTRIBUTION AND EXTENT: The Nashville Basin in Tennessee. The series is of small extent.
