TAYLORBAY SERIES

The Taylorbay series consists of very deep, well drained, moderately slowly permeable soils that formed in silty alluvium These level to nearly level soils are on the flood plain of the White River in the Western Lowlands of Arkansas; MLRA 131. Slopes range from 0 to 3 percent.

TAXONOMIC CLASS: Fine-silty, mixed, active, thermic Cumulic Hapludolls

TYPICAL PEDON: Taylorbay silt loam - cultivated. (Colors are for moist soils unless otherwise stated.)

Ap--0 to 8 inches, very dark grayish brown (10YR 3/2) silt loam; moderate fine granular structure; very friable; many fine and medium roots; common fine and medium pores; slightly acid; clear smooth boundary.

A--8 to 25 inches, very dark grayish brown (10YR 3/2) silt loam; weak medium and coarse subangular blocky structure; friable; common fine and medium roots; common fine and medium pores; slightly acid; gradual wavy boundary. (Combined thickness of the A horizon ranges from 24 to 40 inches.)

Bw1--25 to 32 inches, brown (10YR 4/3) silt loam; weak medium subangular blocky structure; friable; few fine roots; common fine and medium pores; few fine faint brown (10YR 5/3) iron depletions on faces of some peds; few fine black iron-manganese concentrations; slightly acid; gradual smooth boundary.

Bw2--32 to 47 inches, dark yellowish brown (10YR 4/4) silt loam; weak medium subangular blocky structure; friable; few fine roots; common fine and medium pores; common fine distinct brown (10YR 5/3) iron depletions on faces of some peds; few fine black iron-manganese concentrations; slightly acid; gradual smooth boundary.

Bw3--47 to 56 inches, dark yellowish brown (10YR 4/4) silt loam; weak fine and medium subangular blocky structure; friable; common fine and medium pores; common medium distinct brown (10YR 5/3) iron depletions on faces of some peds; few fine black iron-manganese concentrations; slightly acid; clear smooth boundary. (Combined thickness of the Bw horizon ranges from 26 to 40 inches)

C--56 to 72 inches, brown (10YR 4/3) silty clay loam; structureless, massive; friable; few fine and medium pores; common medium distinct grayish brown (10YR 5/2) iron depletions on faces of some peds; few fine black iron-manganese concretions; neutral.

TYPE LOCATION: Woodruff County, Arkansas; approximately 8 3/4 miles north of Augusta in the NW1/4SW1/4NE1/4, sec. 13, T. 9 N., R. 4 W.; USGS Augusta NE topographic quadrangle; lat. 35 degrees, 24 minutes, 43 seconds N and long. 91 degrees, 21 minutes, 52 seconds W, NAD 83.

RANGE IN CHARACTERCISTICS: Solum thickness ranges from 50 to more than 80 inches. The mollic epipedon ranges from 24 to 40 inches or more in thickness. Reaction ranges from slightly acid to slightly alkaline throughout.

The A horizon has hue of 10YR or 7.5YR, value of 3, and chroma of 2 or 3. The texture is silt loam or silty clay loam.

The Bw horizon has hue of 10YR or 7.5YR, value of 3 or 4, and chroma of 3 or 4. Some pedons have iron accumulations or depletions in shades of brown. Texture is silt loam or silty clay loam.

The C horizon has hue of 10YR, value of 4 or 5 and chroma of 2, 3 or 4. Iron accumulations and depletions range from none to common in shades of brown or gray. Texture is dominantly silt loam or silty clay loam, but ranges to loam, clay loam, silty clay and clay.

COMPETING SERIES: Taylorbay is the only series in this family.

GEOGRAPHIC SETTING: These soils are on level to nearly level natural levee positions and nearly level low ridges in point bar deposits on the flood plain of the White River in the Western Lowlands of Arkansas. Slopes range from 0 to 3 percent. Taylorbay soils formed in silty alluvium from the Ozark Uplands and Western Lowlands. Mean annual rainfall is about 51 inches and mean annual temperature is about 61 degrees F. near the type location.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Kobel, Tipp and Yancopin series. All are on similar landscapes. Kobel soils are in a fine particle-size class, do not have a mollic epipedon and are poorly drained. Tipp soils are in a fine particle-size class and are moderately well drained. Yancopin soils are in a fine-silty particle-size class, do not have a mollic epipedon and are somewhat poorly drained.

DRAINAGE AND PERMEABILITY: Well drained; negligible to low surface runoff: moderate permeability. Unprotected areas of these soils flood for brief to very long periods mostly during the winter and early spring. These soils typically have an apparent seasonal water table at 4 to 6 feet for brief periods in winter and early spring.

USE AND VEGETATION: Most areas are cleared and used for cultivated crops of soybeans, corn, grain sorghum and wheat. Minor areas are used for pasture and hay production. The native vegetation was bottomland hardwood forest of oaks, hickory, pecan, cottonwood and sycamore.

DISTRIBUTION AND EXTENT: The Western Lowlands of northeast Arkansas and southeast Missouri and posibbly the St. Francis Basin of northeast Arkansas and southeast Missouri. The series is of small extent.
