TAXONOMIC CLASS: Siliceous, mesic Humic Psammentic Dystrudepts
TYPICAL PEDON: Mindoro sand - on a 1 percent slope in a cultivated field at an elevation of about 790 feet. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 9 inches; very dark brown (10YR 2/2) sand, dark grayish brown (10YR 4/2) dry; weak medium granular structure parting to weak medium subangular blocky; very friable; common very fine and fine roots; neutral; abrupt wavy boundary. (7 to 12 inches thick)
A--9 to 13 inches; very dark grayish brown (10YR 3/2) sand, dark grayish brown (10YR 4/2) dry; moderate medium subangular blocky structure; very friable; common very fine and fine roots; neutral; abrupt smooth boundary. (0 to 12 inches thick)
AB--13 to 17 inches; dark brown (7.5YR 3/3) sand, brown (7.5YR 5/3) dry; moderate medium subangular blocky structure; very friable; common very fine and fine roots; moderately acid; clear wavy boundary. (0 to 8 inches thick)
Bw1--17 to 21 inches; brown (7.5YR 4/4) sand; moderate medium subangular blocky structure; very friable; few very fine and fine roots; slightly acid; clear wavy boundary.
Bw2--21 to 30 inches; yellowish brown (10YR 5/4) sand; weak medium subangular blocky structure; very friable; few very fine and fine roots; slightly acid; gradual wavy boundary. (Combined thickness of the Bw horizons ranges from 10 to 25 inches.)
BC--30 to 45 inches; brownish yellow (10YR 6/6) sand; weak coarse subangular blocky structure; very friable; slightly acid; clear wavy boundary.
C1--45 to 53 inches; very pale brown (10YR 7/4) sand; single grain; loose; common medium prominent brownish yellow (10YR 6/8) masses of iron accumulation; slightly acid; clear wavy boundary.
C2--53 to 60 inches; very pale brown (10YR 7/3) sand; single grain; loose; many coarse prominent reddish yellow (7.5YR 6/8) masses of iron accumulation; slightly acid.
TYPE LOCATION: LaCrosse County, Wisconsin; about 1 mile east of Burr Oak; 990 feet north and 930 feet west of the southeast corner, sec. 1, T. 18 N., R. 6 W.
RANGE IN CHARACTERISTICS: Thickness of the mollic or umbric epipedon ranges from 10 to 24 inches. Volume of sandstone channers ranges from 0 to 5 percent throughout. Redoximorphic features are betweeen depths of 40 to 60 inches. Saturation for 1 month or more per year in 6 out of 10 years occurs at 40 to 60 inches.
The Ap or A surface horizons have hue of 7.5YR or 10YR; value of 2 or 3; and chroma of 1 to 3. Reaction typically ranges from strongly acid to slightly acid but ranges to neutral where limed.
The AB horizon or subsurface A horizon have hue of 7.5YR or 10YR, value of 3 or 4, and chroma of 2 or 3. Reaction typically ranges from strongly acid to slightly acid but ranges to neutral where limed.
The Bw horizon has hue of 7.5YR or 10YR; value of 3 to 5; and chroma of 4 to 6. It is sand or fine sand. Reaction typically ranges from strongly acid to slightly acid but ranges to neutral where limed.
The BC horizon has hue of 7.5YR or 10YR; value of 4 to 6, and chroma of 4 to 8. It is sand or fine sand. Reaction ranges from moderately acid to slightly acid.
The C horizon has hue of 7.5YR, or 10YR; value of 4 to 7; and chroma of 1 to 8. It is sand or fine sand. Reaction ranges from moderately acid to neutral.
COMPETING SERIES: This is the Impact series. The Impact soils do not have redoximorphic features with a depth of 40 to 60 inches.
GEOGRAPHIC SETTING: Mindoro soils are on stream terraces. Slopes range from 0 to 3 percent. Mean annual precipitation ranges from 28 to 33 inches. Mean annual air temperature is 46 to 50 degrees. Frost free period ranges from about 135 to 150 days. Elevation ranges from 750 to 890 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: Near the Type Location these include the excessively drained Impact and Tarr and the somewhat poorly drained Majik soils. The Impact soils and the Majik soils form a drainage sequence with Mindoro soils. The Majik soils have a thinner surface layer. The Tarr soils are on slightly higher landscape positions where the surface layer is thinner or lighter colored or both.
DRAINAGE AND PERMEABILITY: Moderately well drained. Permeability is rapid. Mindoro soils have an apparent seasonal high water table at a depth of 3.5 to 6 feet for 1 month or more per year at some time during the period of October to June in 6 or more out of 10 years.
USE AND VEGETATION: Some areas of Mindoro soils are cultivated. Corn, soybeans, small grains, and hay are the principal crops. Some areas are used for woodland. Native vegetation is mixed prairie grasses or a combination of widely spaced oaks and mixed prairie grasses.
DISTRIBUTION AND EXTENT: Mindoro soils will be found throughout the "Driftless Area" in the siliceous sandy alluvium that is derived from the Wonewoc sandstone. As of 1998, they have been correlated only in LaCrosse County, Wisconsin.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: St. Paul, Minnesota.
SERIES ESTABLISHED: LaCrosse County, Wisconsin, 2001. The name is from a small town in the northern part of LaCrosse County.
REMARKS: Diagnostic horizons and features recognized in this pedon are: umbric epipedon - 0 to 17 inches (Ap, A, Ab); siliceous feature - have less than 10 percent weatherable minerals in the particle-size control section (0.02 - 2.0 mm fraction); Base saturation by NH4OAc is less than 50 percent in some horizon within 180 cm.
