LOCATION LAKEPARK MNEstablished Series
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, frigid Cumulic Endoaquolls
TYPICAL PEDON: Lakepark clay loam, on a 1 percent concave slope, in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 8 inches; black (10YR 2/1) clay loam; very dark gray (10YR 3/1) dry; weak fine subangular blocky structure; friable; about 1 percent gravel; slightly acid; abrupt smooth boundary.
A1--8 to 20 inches; black (N 2/0) clay loam; very dark gray (N 3/0) dry; weak fine subangular blocky structure; friable; about 1 percent gravel; neutral; gradual smooth boundary.
A2--20 to 28 inches; very dark gray (N 3/0) clay loam, dark gray (N 4/0) dry; weak medium subangular blocky structure; friable; about 1 percent gravel; slightly acid; clear smooth boundary. (Combined thickness of the A horizon is 24 to 60 inches.)
Bg--28 to 34 inches; olive gray (5Y 5/2) silty clay loam; weak medium subangular blocky structure; friable; few fine distinct dark yellowish brown (10YR 4/6) Fe concentrations; about 1 percent gravel; neutral; clear smooth boundary. (0 to 20 inches)
Cg--34 to 60 inches; light brownish gray (2.5Y 6/2) loam; massive; friable; common medium distinct yellowish brown (10YR 5/8) Fe concentrations; about 7 percent gravel; strongly effervescent; slightly alkaline.
TYPE LOCATION: Becker County, Minnesota; about 5 miles southwest of Lake Park; located about 1,600 feet east and 200 feet south of the northwest corner of section 19, T. 139 N., R. 43 W; Lake Park SW topographic quadrangle; lat. 46 degrees 50 minutes 52 seconds N. and long. 96 degrees 10 minutes 07 seconds W., NAD 83.
RANGE IN CHARACTERISTICS: The depth to carbonates ranges from 25 to 50 inches. The mollic epipedon typically is 24 to 40 inches thick but ranges to 60 inches thick in some pedons. Coarse fragments are typically not present in the upper part but range form 0 to 5 percent by volume. The lower part has 2 to 8 percent rock fragments by volume. The soil moisture control section is dry 20 to 35 consecutive days during the 120 days following the summer solstice in most years.
The A horizon has hue of 10YR to 5Y or is neutral, value of 2 or 3 and chroma of 0 to 2. It is silty clay loam, clay loam, loam or silt loam. It is slightly acid to slightly alkaline.
The Bg horizon has hue of 2.5Y or 5Y, value of 4 or 5 and chroma of 1 or 2, It has few through many redoximorphic features in some to all parts. It is clay loam, silty clay loam or loam. It is neutral or slightly alkaline.
Some pedons have Bk horizons.
The Cg horizon has hue of 2.5Y or 5Y, value of 4 to 6 and chroma of 1 or 2. It commonly has redoximorphic features in all parts. It is clay loam or loam. It is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Eagleton, Kovich, Mannixlee(T), and Welch series. Eagleton and Welch soils are dry in the soil moisture control section for 35 to 45 consecutive days following the summer solstice in most years. Kovich soils have a skeletal lithologic discontinuity in the particle-size control section. Mannixlee soils have skeletal material below a depth of 40 inches.
GEOGRAPHIC SETTING: Lakepark soils are on lower footslopes, toeslopes, and drainways on glacial moraines and till plains. Slopes are plane or concave with 0 to 3 percent gradients. These soils formed in loamy colluvium derived from glacial drift and underlying loamy glacial till. Mean annual air temperature ranges from 38 to 45 degrees F. Mean annual precipitation ranges from 22 to 28 inches. Frost-free period ranges from 90 to 140 days. Elevation ranges from 900 to 1,800 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Langhei, Formdale, Barnes, Aazdahl, Flom and Quam soils. Langhei, Formdale and Barnes soils are well drained and are on steeper slopes. Aazdahl soils are moderately well drained and are higher lying. Flom soils are poorly drained soils and have mollic epipedons less than 24 inches thick. Quam soils are very poorly drained and are in depressions.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is slow. Permeability is moderately slow. The apparent seasonal high water table is at a depth of .5 to 1.5 feet from November to June in normal years.
USE AND VEGETATION: Most areas are cultivated. Small grains, corn, and soybeans are the principal crops. Native vegetation is tall grass prairie.
DISTRIBUTION AND EXTENT: Western Minnesota, the series is widely distributed but inextensive.
