JESSUP SERIES


The Jessup series consists of deep or very deep, well drained soils formed in loess and the underlying till and residuum from calcareous gray shale and thin strata of limestone. These soils are on uplands. Slope ranges from 1 to 35 percent. Mean annual precipitation is about 1067 mm (42 inches), and mean annual air temperature is about 12 degrees C (54 degrees F).

COMPETING SERIES: These are the Beasley, Bledsoe, Bonnell, Brashear, Bratton, Bucklick, Caneyville, Cosperville, Donahue, Eden, Elba, Enott, Estate, Faywood, Fredonia, Haggatt, Heitt, Heverlo, Kewaunee, Lowell, Markland, Milton, Mountpleasant, Muncie, Shrouts, and Vandalia series. Of these, only Bonnell, Cosperville, Heverlo, Kewaunee, Milton, Mountpleasant, and Muncie soils contain glacial erratics. Bonnell, Kewaunee, and Muncie soils have the lower part of their sola formed in till and have some crystalline rocks in the lower part of the solum. Cosperville soils do not have a loess mantle and textures containing more than 50 percent silt in the upper part of the series control section. Heverlo soils have a paralithic contact within a depth of 102 cm (40 inches). Milton soils have a lithic contact within a depth 102 cm (40 inches). Mountpleasant soils have carbonates within a depth of 91 cm (36 inches).

GEOGRAPHIC SETTING: Jessup soils are on glaciated uplands near the margin of the Illinoian till sheet. They are on upper shoulders below areas of thicker till or are on narrow, beveled interfluves. Slope ranges from 1 to 35 percent. The soils formed in a mantle of loess 25 to 61 cm (10 to 24 inches) thick and in the underlying weathered Illinoian till and residuum from calcareous Ordovician shale and thin strata of limestone. Mean annual precipitation ranges from 965 to 1168 mm (38 to 46 inches). Mean annual air temperature ranges from 11 to 14 degrees C (51 to 57 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cincinnati, Edenton, Fairmount, Faywood, Loudon, Otway, and Rossmoyne soils. Cincinnati and Rossmoyne soils are on broad interfluves having a thicker deposit of till and have fragipans. Edenton soils are moderately deep to bedrock, and are on upper shoulders and backslopes. Fairmount, Faywood, and Otway soils are in unglaciated areas and are on the steeper slopes that are dominated by limestone. The moderately well drained Loudon soils are on toeslopes and on broader interfluves than Jessup soils.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The potential for surface runoff is medium to very high. Saturated hydraulic conductivity is moderately low. Permeability is slow.

USE AND VEGETATION: Jessup soils are in cropland and pasture. Tobacco, corn, wheat, and clover-grass mixtures are the common crops. Native vegetation is hardwood forest.

DISTRIBUTION AND EXTENT: MLRA 114A in southwestern Ohio and MLRA 121 in northern Kentucky. The series is of small extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Indianapolis, Indiana.

SERIES ESTABLISHED: Brown County, Ohio, 1930.

REMARKS: Diagnostic horizon and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 18 cm (Ap horizon).
Argillic horizon: from a depth of 30 to 137 cm (Bt, 2Bt, 3Bt horizon).
Paralithic contact: at 163 cm (top of the 3Cr horizon).

ADDITIONAL DATA: Laboratory data for the typical pedon will be available (AD-30). Preliminary data indicates that clay mineralogy is well into the mixed class but there is an increase in illitic clay minerals in the lower part of the control section.
