REESVILLE SERIES

The Reesville series consists of very deep, somewhat poorly drained soils formed in loess and are underlain by loamy till. They are on till plains and moraines. Slope ranges from 0 to 7 percent.

COMPETING SERIES: These are the Appleriver, Blair, Bunkum, Fishhook, Freeburg, Geff, Glenford, Keene, Muren, Sugarvalley, Torox, and Xenia series. Appleriver soils have a paralithic contact within a depth of 152 cm (60 inches). Blair, Bunkum, Freeburg, and Muren soils are more than 140 cm (55 inches) to carbonates. Fishhook, Geff, Torox, and Xenia soils have subhorizons that have more than 10 percent sand within a depth of 102 cm (40 inches). Glenford soils are stratified within the series control section. Keene soils have rock fragments of shale and siltstone lithology within the series control section. Sugarvalley soils have a 2B horizon developed in till within the series control section.

GEOGRAPHIC SETTING: Reesville soils are on loess capped till plains of Wisconsinan age. Slope ranges from 0 to 7 percent. The soils formed in 102 to 152 cm (40 to 60 inches) of loess and are underlain by loam, clay loam, or silt loam till. Mean annual precipitation ranges from 914 to 1067 mm (36 to 42 inches). Mean annual air temperature ranges from 10 to 12 degrees C (50 to 54 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Birkbeck, Fincastle, Ragsdale, Whitson, and Xenia soils. The moderately well drained Birkbeck soils are on higher topographic positions. The somewhat poorly drained Fincastle and moderately well drained Xenia soils are in areas that have a thinner loess mantle. The poorly drained Ragsdale and Whitson soils are in areas that have a thicker mantle of loess or other silty sediments.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Depth to the top of a perched seasonal high water table ranges from 15 to 46 cm (0.5 to 1.5 feet) during winter and spring in normal years. Potential for surface runoff is negligible to medium. Saturated hydraulic conductivity is moderately high in the solum and moderately low in the substratum. Permeability is moderate in the solum and moderately slow or slow in the substratum.

USE AND VEGETATION: Reesville soils are cultivated. Principal crops are corn, soybeans, wheat, grasses and legumes.

DISTRIBUTION AND EXTENT: Southwestern Ohio, south-central and western Indiana, and eastern Illinois; MLRAs 108A, 111A, 111D, 114B, and 115A. The type location is in MLRA 111D. The series is of moderate extent.

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

SERIES ESTABLISHED: Fayette and Union Counties, Indiana, 1958.

REMARKS: Reesville soils were previously classified as Aeric Epiaqualfs. Field investigations, including transects, determined that redoximorphic depletions with chroma of 2 or less contribute to less than 50 percent of total color for the upper portion of the argillic.

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 96 cm (Bt, BCt horizons).
Aquic conditions: redox features immediately below Ap, but are in less than 50 percent of the matrix to a depth greater than 200 cm.

ADDITIONAL DATA: Characterization data is available from the Kellogg Soil Survey Laboratory (KSSL), Lincoln, Nebraska.
