Bt1--11 to 16 inches; dark brown (10YR 4/3) clay loam; moderate fine subangular blocky structure; firm; few faint clay films on faces of peds; moderately acid; clear smooth boundary.
Bt2--16 to 23 inches; dark brown (10YR 4/3) clay; moderate fine subangular blocky structure; firm; common distinct clay films on faces of peds; moderately acid; clear smooth boundary.
Bt3--23 to 28 inches; brown (10YR 5/3) clay loam; weak medium subangular blocky structure; friable; few distinct clay films on faces of peds; moderately acid; clear smooth boundary. (Combined thickness of Bt horizons is 10 to 24 inches.)
2BC--28 to 40 inches; variegated brown (10YR 5/3), grayish brown (10YR 5/2) and yellowish brown (10YR 5/4) loamy sand; very friable; massive; common clay bridging between sand grains; slightly acid; clear smooth boundary. (0 to 12 inches thick)
2C--40 to 60 inches; brown (10YR 5/3), grayish brown (10YR 5/2) and olive brown (2.5Y 4/4) sand; single grain; loose; slight effervescence; mildly alkaline.
TYPE LOCATION: Carver County, Minnesota; about 2 miles east of East Union; 1270 feet west and 1280 feet south of northeast corner of sec. 1, T. 114 N., R. 24 W.
RANGE IN CHARACTERISTICS: Solum thickness and depth to free carbonates is 24 to 50 inches. The depth to sandy and gravelly sediments ranges from 20 to 40 inches. Rock fragments of mixed lithology make up 0 to 10 percent of the volume of the upper sediments, and the lower sediments contain as much as 25 percent rock fragments by volume. The thickness of the mollic epipedon ranges from 9 to 18 inches.
The Ap or A horizon has hue of 10YR, value of 2 or 3, and chroma of 1 or 2. It is typically silt loam or loam, but in some pedons is silty clay loam, sandy loam or clay loam. It is moderately acid to neutral.
The Bt horizon has hue of 10YR or 2.5Y, value of 3 to 5; and chroma of 3 or 4. It is typically clay, silty clay or clay loam, but thin strata of silty clay loam or loam are in some pedons. It is moderately acid or slightly acid.
The 2C horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 2 to 5. It is typically, coarse sand, sand or their gravelly analogues and stratified in many pedons. Strata of fine sand, loamy fine sand or loamy sand are in some pedons. It is mildly alkaline or moderately alkaline.
COMPETING SERIES: No other series is in the family. Closely related series are the Dakota, Fairhaven, and Wadena series. These soils all have less than 35 percent clay in their particle-size control sections.
GEOGRAPHIC SETTING: These soils are on river terraces and outwash plains. Slopes are plane and slightly convex and range from 0 to 6 percent. They formed in loamy and clayey sediments and underlying sandy and gravelly sediments. Mean annual temperature is 45 to 50 degrees F. Mean annual precipitation is 28 to 32 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Biscay, Dakota, Fairhaven, and Wadena soils. The poorly drained Biscay soils are on lower lying flats and drainageways. The well drained Dakota, Fairhaven and Wadena soils are on positions similar to that of the Kasota soils.
DRAINAGE AND PERMEABILITY: Well drained. Surface runoff is slow to medium. Permeability is moderately slow in the solum and rapid in the underlying sediments.
USE AND VEGETATION: Most is under cultivation with corn and soybeans being the principal crops. Native vegetation is mostly tall grass prairie.
DISTRIBUTION AND EXTENT: Southern Minnesota. Small extent.

REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon - zone from the surface of the soil to a depth of 12 inches (Ap, A, and AB horizons); argillic horizon - zone from about 12 to 28 inches (Bt horizons). See Minnesota Agricultural Experiment Station Soil Survey Lab CFC No. 820, for results on a representative pedon.
