TARLTON SERIES

The Tarlton series consists of moderately deep, moderately well drained soils formed in till and the underlying clayey residuum weathered from shale. They are on till plains. Slope ranges from 0 to 12 percent. Mean annual precipitation is about 914 mm (36 inches), and mean annual air temperature is about 11 degrees C (51 degrees F).

TAXONOMIC CLASS: Fine, mixed, active, mesic Aquic Hapludalfs

COMPETING SERIES: These are the Banister, Branchville, Cardinal, Celina, Eudy, Hartville, Jerktail, Loudon, and Whippany series. Banister, Branchville, Cardinal, Celina, Hartville, Jerktail, Loudon, and Whippany soils do not have a paralithic or lithic contact within a depth of 102 cm (40 inches). Eudy soils have a mean annual soil temperature above 13 degrees C (55 degrees F) and are formed in loess and the underlying residuum from cherty dolostone.

GEOGRAPHIC SETTING: Tarlton soils are in glaciated areas near the margin of the ice sheets where thin layers of till were deposited on acid shale. These soils often occur on dissected areas below till plains having thicker till or are on leveled interfluves that have a thin covering of till. Slope ranges from 0 to 12 percent. The soils formed in till and the underlying clayey residuum weathered from shale. Mean annual precipitation ranges from 813 to 1168 mm (32 to 46 inches). Mean annual air temperature ranges from 9 to 12 degrees C (49 to 53 degrees F). Frost-free period is 155 to 165 days. Elevation is 183 to 366 meters (600 to 1200 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Amanda, Celina, and Centerburg soils. These very deep soils formed entirely in till and are on similar landscape positions as the Tarlton soils.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. The depth to the top of an intermittent perched high water table ranges from 46 to 91 cm (1.5 to 3.0 feet) between January and April in normal years. The potential for surface runoff is low to high depending on slope gradient. Saturated hydraulic conductivity is moderately high in the upper part of the solum and moderately low in the lower part. Permeability is moderate or moderately slow in the upper part of the solum and slow in the lower part.

USE AND VEGETATION: Most areas are used for hay and pasture. Some areas are used for cropland and woodland. Native vegetation is mixed hardwood forest.

DISTRIBUTION AND EXTENT: Central Ohio; MLRA 111A and 111E. The type location is in MLRA 111A. The series is of small extent, about 100 acres, with more expected to be correlated in Pickaway and Hocking Counties to total about 4,000 acres.

SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: AMHERST, MASSACHUSETTS

SERIES ESTABLISHED: Fairfield County, Ohio, 1994.

REMARKS: This series is based on data developed in Hocking and Pickaway Counties, as well as Fairfield County. The representative pedon is the Celina Variant from Pickaway County. This soil was previously mapped as Celina Variant in Pickaway County and Cana Variant in Hocking County and was classified as Fine-loamy, mixed, mesic Aquic Hapludalfs.

Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 15 cm (Ap horizon).
Argillic horizon: from a depth of 15 to 53 cm (Bt horizon).
Paralithic contact: at 86 cm (top of the 2Cr layer).
Lithic contact: at 99 cm (top of the 2R layer).
Aquic conditions: redox features visible in horizons between the depths of 28 and 86 cm.

ADDITIONAL DATA: Characterization data is available from The Ohio State University Soil Characterization Laboratory for pedon HY-55. HY-55 is not the representative pedon data, but data from a similar pedon.
