COMPETING SERIES: This is the Trumbull series. Trumbull soils averages between 40 and 60 percent clay in the particle-size control section.
GEOGRAPHIC SETTING: Condit soils are on ground moraines of Wisconsinan age. Slope ranges from 0 to 2 percent. The soils formed in loamy till. Climate is humid and temperate. Mean annual precipitation ranges from 864 to 1067 mm (34 to 42 inches). Mean annual air temperature ranges from 9 to 13 degrees C (49 to 55 degrees F). Frost-free period is 145 to 180 days. Elevation is 244 to 305 meters (800 to 1,000 feet) above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Alexandria, Amanda, Bennington, Cardington, Centerburg, and Pewamo soils that are in toposequences with Condit soils. The well drained Alexandria and Amanda soils, the somewhat poorly drained Bennington soils, and the moderately well drained Cardington and Centerburg soils are on higher landscape positions or more sloping areas along drainageways. The very poorly drained Pewamo soils have mollic epipedons and are on similar positions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Very poorly drained. The depth to the top of an intermittent perched high water table ranges from 30 cm (1 foot) above the surface to 30 cm (1 foot) below the surface between November and May in normal years. The potential for surface runoff is negligible to low. Saturated hydraulic conductivity is moderately low. Permeability is slow.
USE AND VEGETATION: Most areas are cultivated. Some areas are in pasture or woodland. Corn, soybeans, small grain, and hay are the principal crops. Native vegetation is mixed hardwoods.
DISTRIBUTION AND EXTENT: Central and north-central Ohio; MLRAs 111E and 139. The type location is in MLRA 111E. The series is of moderate extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Licking County, Ohio, 1930.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 25 cm (Ap horizon).
Argillic horizon: from a depth of 25 to 178 cm (Btg, Bt horizons).
Aquic conditions: redox features present in all horizons below the ochric epipedon.
ADDITIONAL DATA: Characterization data for this series is available for pedons CY-2 and TR-9, from the Soil Characterization Laboratory, at The Ohio State University, Columbus, OH. Engineering test data, characterization data, percolation data, and bearing strength data are available for these pedons.
