LOCATION IMPACT WIEstablished Series
TAXONOMIC CLASS: Siliceous, mesic Humic Psammentic Dystrudepts
TYPICAL PEDON: Impact sand - on a 3 percent slope in a cultivated field at an elevation of about 890 feet. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 8 inches; black (10YR 2/1) sand, brown (7.5YR 5/2) dry; weak medium subangular blocky structure; very friable; many very fine and medium and a few coarse roots; strongly acid; abrupt smooth boundary. (7 to 12 inches thick)
A--8 to 12 inches; very dark grayish brown (10YR 3/2) sand, brown (10YR 5/3) dry; weak coarse subangular blocky structure; very friable; many very fine and medium roots; strongly acid; clear smooth boundary. (0 to 12 inches thick)
AB--12 to 15 inches; dark brown (10YR 3/3) sand; weak medium subangular blocky structure; very friable; common fine and medium roots; strongly acid; clear smooth boundary. (0 to 8 inches thick)
Bw--15 to 36 inches; dark yellowish brown (10YR 4/4) sand; weak medium subangular blocky structure; very friable; strongly acid; abrupt smooth boundary. (10 to 25 inches thick)
C--36 to 60 inches; very pale brown (10YR 7/4) sand; single grain; loose; slightly acid.
TYPE LOCATION: Monroe County, Wisconsin; about 6 miles east of Sparta; 520 feet east and 1,770 feet south of the northwest corner, sec. 19, T. 17 N., R. 2 W.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 20 to 42 inches. Thickness of the mollic or umbric epipedon ranges from 10 to 24 inches. Base saturation by NH4OAc is less than 50 percent in some horizon within 180 cm. Volume of sandstone channers ranges from 0 to 15 percent throughout. Reaction typically ranges from extremely acid to moderately acid in the solum but ranges to neutral in the upper part, where the soil is limed. Reaction ranges from strongly acid to slightly acid in the substratum.
The Ap or A horizons hve hue of 7.5YR or 10YR; value of 2 or 3; and chroma of 1 to 3. They are sand, fine sand, loamy sand, or loamy fine sand.
The AB horizon has hue of 7.5YR or 10YR. It is sand, fine sand, loamy sand, or loamy fine sand.
The Bw horizon has hue of 7.5YR or 10YR; value of 3 or 4; and chroma of 4 to 6. It is loamy sand, loamy fine sand, sand, or fine sand.
Some pedons have a BC horizon with hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 to 8. It is sand or fine sand.
The C horizon has hue of 5YR, 7.5YR, or 10YR; value of 4 to 7; and chroma of 1 to 8. It is sand or fine sand.
COMPETING SERIES: There are no competing series. Other series in closely related families are Sparta, Tarr, Trempe, and Zumbro. Sparta, Trempe, and Zumbro soils have mollic epipedons and mixed mineralogy. Tarr soils have an ochric epipedon.
GEOGRAPHIC SETTING: These soils are on stream terraces and pediments. Slopes range from 0 to 6 percent. These soils in siliceous sandy alluvium or residuum. Mean annual precipitation ranges from 28 to 33 inches. Mean annual temperature is 46 to 51 degrees F. The frost free period ranges from about 135 to 160 days. Elevation ranges from about 700 to 1000 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Tarr and Tint soils. Tarr soils are on similar landscape positions where the surface layer is thinner or lighter colored or both. Tint soils are in slightly lower landscape positons where the surface layer is thinner or lighter colored or both and where there is a water table at 40 to 60 inches.
DRAINAGE AND PERMEABILITY: Excessively drained. Surface runoff is slow. Permeability is rapid.
USE AND VEGETATION: Most areas of this soil are used for woodland. Common trees are northern pin oak and jack pine. Some areas are used for cropland or pastureland.
DISTRIBUTION AND EXTENT: West-central Wisconsin. It is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Monroe County, Wisconsin, 1981.
REMARKS: A new series is needed for the moderately well drained phase. The MWD SIR will be maintained until the new series is proposed. Diagnostic horizons and features recognized in this pedon are: umbric epipedon - 0 to 15 inches (Ap, A, Ab); siliceous feature - have less than 10 percent weatherable minerals in the particle-size control section (0.02 - 20 mm fraction).
