SLEETH SERIES

The Sleeth series consists of very deep, somewhat poorly drained soils that are deep to calcareous, stratified gravelly and sandy outwash. Sleeth soils formed in loamy outwash. A mantle of loess or other silty material is as much as 51 cm (20 inches) thick in some areas. They are on outwash terraces, stream terraces, and outwash plains. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 1016 mm (40 inches), and mean annual temperature is about 11 degrees C (52 degrees F).

TAXONOMIC CLASS: Fine-loamy, mixed, active, mesic Aeric Endoaqualfs

COMPETING SERIES: These are the Angola, Appleton, Ayrshire, Burdett, Crawleyville, Darien, Digby, Mitiwanga, Mongle, Nuhi, Ovid, Shadeland, and Whitaker series. Angola, Mitiwanga, Nuhi, and Shadeland soils have a lithic contact within a depth of 102 cm (40 inches). Appleton and Ovid soils are less than 102 cm (40 inches) to the base of the argillic horizon. Ayrshire, Crawleyville, and Whitaker soils average less than 15 percent rock fragments in the lower part of the series control section. Burdett and Darien soils do not have textures with as much as 85 percent sand in the lower part of the series control section. Digby soils have subhorizons that are finer than loamy coarse sand in the lower part of the series control section. Mongle soils are more acid that slightly alkaline in the lower part of the series control section.

GEOGRAPHIC SETTING: Sleeth soils are on outwash terraces, stream terraces, and outwash plains. Slope ranges from 0 to 2 percent. The soils formed in loamy outwash in areas of Wisconsinan glaciation. A mantle of loess or other silty material is as much as 51 cm (20 inches) thick in some areas. They are deep to calcareous, stratified gravelly and sandy outwash. Mean annual precipitation ranges from 889 to 1143 mm (35 to 45 inches). Mean annual temperature ranges from 9 to 12 degrees C (48 to 54 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Fox, Nineveh, Ockley, Thackery, and Westland soils. The well drained Fox, Nineveh, and Ockley soils are on terrace risers and on swells on outwash plains. The moderately well drained Thackery soils are on swells on outwash plains and higher lying treads on terraces. The poorly drained or very poorly drained Westland soils are in depressions.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Depth to the top of an intermittent apparent high water table ranges from 15 to 61 cm (0.5 to 2.0 feet) during the winter and early spring in normal years. Potential for surface runoff is negligible to low. Saturated hydraulic conductivity is moderately high in the loamy outwash and very high in the underlying gravelly and sandy outwash. Permeability is moderate in the loamy outwash and very rapid in the underlying gravelly and sandy outwash.

USE AND VEGETATION: Most areas are used to grow corn, soybeans, and small grain (mostly wheat). Native vegetation is deciduous forest.

DISTRIBUTION AND EXTENT: Mainly in MLRAs 111A and 111D, and to a lesser extent in MLRAs 97, 98 and 114A in Indiana, Michigan, and Ohio. The type location is in MLRA 111A. The series is of moderate extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 36 cm (Ap, E horizons).
Albic horizon: from a depth of 23 to 36 cm (E horizon).
Argillic horizon: from a depth of 36 to 127 cm (Bt, Btg horizons).
Aquic conditions: redox depletions and/or concentrations in all horizons below 23 cm.

Loamy and till substratum phases have been recognized and may become new series as subsets of soil surveys with these phases are updated.

Representative NASIS data mapunit for this pedon is DMU ID 156145 in MO 11.
