COMPETING SERIES: These are the Canfield, Nockamixon, and Rittman series. Canfield and Rittman soils do not extend into residual parent materials. Nockamixon soils have a solum 30 to 50 inches thick.
GEOGRAPHIC SETTING: Teegarden soils formed in loess, Illinoian or early Wisconsinan age till, and material weathered from the underlying Pennsylvanian age shale, fine-grained sandstone, or siltstone. They are on till plains. Slope ranges from 2 to 15 percent. Mean annual precipitation ranges from about 35 to 40 inches, and mean annual temperature ranges from about 50 to 53 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Berks, Gilpin, Kensington, and Mechanicsburg soils. The well drained, moderately deep, Berks and Gilpin soils are on nearby interfluves, side slopes, nose slopes, and head slopes. The deep Kensington soils are on adjacent interfluves, side slopes, nose slopes, and head slopes. The well drained, deep and very deep, Mechanicsburg soils are on nearby interfluves, head slopes, nose slopes, and side slopes.
DRAINAGE AND PERMEABILITY: Moderately well drained. The potential for surface runoff is medium or high. Permeability is moderate above the fragipan, slow in the fragipan and moderate to slow below the fragipan, above bedrock. In undisturbed areas the depth to the top of a perched seasonal high water table is at a depth of 1.0 to 2.0 feet during December to May in normal years.
USE AND VEGETATION: These soils are commonly used to grow corn, oats, wheat, mixed hay, and pasture. A few areas are in woodland. Natural vegetation is mixed hardwood forest composed primarily of sugar maple, oak, and hickory.
DISTRIBUTION AND EXTENT: Northeastern Ohio and possibly northwestern Pennsylvania. MLRA 139. The soils are of small extent, about 9600 acres.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Columbiana County, Ohio, 2005.
REMARKS: Teegarden soils were formerly mapped as Titusville and Hanover soils in the 1968 Soil Survey of Columbiana County, Ohio. Field investigations in the current modernization project indicate the till is thinner to the underlying residuum.
