TYPE LOCATION: Juneau County, Wisconsin; about 4 miles east and 1 mile south of Mauston; about 160 feet south and 460 feet east of the northwest corner of sec. 24, T. 15 N., R. 4 E. USGS Round Bluff, Wis. Quad. Latitude - 43 degrees 46 minutes 26 seconds N. Longitude - 89 degrees 58 minutes 25 seconds W. NAD 27.
RANGE IN CHARACTERISTICS: Depth to the base of soil development ranges from 20 to 40 inches and coincides with depth to sandstone. The particle-size control section averages less than 15 percent silt plus clay. Some pedons have up to 15 percent by volume of coarse fragments consisting of ironstone and sandstone channers and flagstones. Reaction naturally ranges from extremely acid to slightly acid throughout the soil but ranges to neutral in the upper part, where the soil is limed. Redox accumulations typically are throughout the soil below the Ap or A horizon. Redox depletions with chroma of 2 or less and saturation occur within a depth of 40 inches.
The A horizon has hue of 10YR, value of 2 or 3, and chroma of 1 or 2. Cultivated pedons have an Ap horizon with hue of 10YR, value of 3 or 4, and chroma of 2 or 3. Texture of the A or Ap horizon is loamy sand.
The E horizon has hue of 10YR, value of 4 or 5, and chroma of 2 or 3. Texture is loamy sand, loamy fine sand, sand, or fine sand.
The Bw horizon has hue of 7.5YR, 10YR, or 2.5Y; value of 3 to 5; and chroma of 3 to 6. Texture is loamy sand, loamy fine sand, sand, or fine sand.
The BC horizon has hue of 7.5YR, 10YR, or 2.5Y; value of 4 to 7; and chroma of 2 to 8. Texture is sand or fine sand.
The Cr horizon has hue of 10YR, value of 4 to 6 and chroma of 3 to 6. Typically it is weakly cemented sandstone. Some pedons have a Cr horizon, some pedons have an R horizon, and some have a Cr horizon which grades with depth to an R horizon.
COMPETING SERIES: These are the Algansee, Altmar, Birchwood, Brems, Brockatonorten, Deerfield, Elnora, Fortress, Meckling, Morocco, Ottokee, Tedrow, and Zaborosky series. None of these soils have a lithic contact at a depth of 20 to 40 inches.
GEOGRAPHIC SETTING: The Partridge soils are on flats and in drainageways and depressions on outwash plains, stream terraces, and some nearby upland areas. Slopes range from 0 to 3 percent. These soils formed in sandy outwash or sandy eolian deposits overlying sandstone. Some pedons have the lower part of the solum or the substratum in sandy residuum weathered from sandstone. Mean annual precipitation ranges from 26 to 35 inches. Mean annual air temperature ranges from 46 to 48 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: In the vicinity of the frigid-mesic temperature line, these are the mesic Elkmound and frigid Plainbo soils. The excessively drained Plainbo soils are in similar or slightly higher landscape positions contiguous to the Partridge soils. The well drained Elkmound soils occupy similar or slightly higher landscape positions contiguous to Partridge soils but have finer textured control sections and Elkmound soils are 10 to 20 inches deep to sandstone.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is negligible or very low. Permeability is rapid. These soils have a perched seasonal high water table at a depth of 1 to 3 feet for some time in most years.
USE AND VEGETATION: Most areas of this soil are used for woodland. Some areas are used for cropland or pastureland. Common crops are corn, small grains, and hay. Some areas, which were used for cropland in the past, have been planted to pine trees or allowed to revert to native trees. Native vegetation is principally jack pine, pin oak, and aspen.
DISTRIBUTION AND EXTENT: Juneau County, Wisconsin. The Partridge soils are of small extent.
