STATELINE SERIES
The Stateline series consists of deep, poorly drained, very slowly permeable soils that formed in loess or loamy sediments and underlying clayey paleosol. These soils are in shallow swales and on broad low lying flats of upland till plains with slopes less than 2 percent. The mean annual temperature is about 45 degrees F, and the mean annual precipitation is about 30 inches.
TAXONOMIC CLASS: Fine, smectitic, mesic Vertic Epiaqualfs
TYPICAL PEDON: Stateline silt loam with a slope of less than 1 percent in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 7 inches; very dark gray (10YR 3/1) silt loam, gray (10YR 5/1) dry; weak fine granular structure; friable; neutral; abrupt smooth boundary. (6 to 10 inches thick)
Eg1--7 to 10 inches; dark grayish brown (2.5Y 4/2) silty clay loam; light gray (10YR 7/1) dry; many fine prominent yellowish brown (10YR 5/8) mottles; moderate thin platy structure; friable; very strongly acid; abrupt wavy boundary.
Eg2--10 to 14 inches; dark grayish brown (2.5Y 4/2) silty clay loam, light gray (10YR 7/1) dry; many fine prominent yellowish brown (10YR 5/8) mottles; moderate thin platy structure; friable; very strongly acid; clear wavy boundary. (Combined thickness of E horizons is 6 to 12 inches.)
BEg--14 to 18 inches; dark grayish brown (2.5Y 4/2) silty clay loam, many fine prominent yellowish brown (10YR 5/8) mottles; weak coarse prismatic structure parting to strong fine subangular blocky; firm; many distinct clean sand and silt grains on faces of peds; common distinct clay films on faces of peds; very strongly acid; clear wavy boundary. (0 to 8 inches thick)
2Btg1--18 to 24 inches; olive gray (5Y 5/2) silty clay; common coarse faint grayish brown (10YR 5/2) mottles; strong medium prismatic structure parting to strong fine subangular blocky; firm; many distinct clean sand and silt grains coating faces of peds; common distinct dark grayish brown (10YR 4/2) clay films on faces of peds; strongly acid; clear wavy boundary.
2Btg2--24 to 36 inches; dark gray (10YR 4/1) clay; common coarse faint grayish brown (10YR 5/2) mottles; strong medium and coarse prismatic structure parting to strong fine subangular blocky; very firm; many distinct clean sand and silt grains on faces of peds; many faint clay films on faces of peds; strongly acid; abrupt wavy boundary.
2Btg3--36 to 60 inches; grayish brown (10YR 5/2) clay; common medium distinct olive (5Y 5/4) mottles; strong coarse prismatic structure; very firm; strongly acid.
TYPE LOCATION: Mower County, Minnesota; Nevada Township; 2,100 feet east and 550 feet south of the northwest corner of sec. 7, T. 101 N., R. 17 W.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 40 to about 70 inches and the depth to carbonates is below 60 inches. The loamy sediment ranges from 16 to 30 inches thick. This sediment typically lacks coarse fragments, but the lower part in some pedons has a few.
The A horizon has hue of 10YR or 2.5Y and value of 2 or 3 and chroma of 1 or 2. It is silt loam, loam, or silty clay loam. The reaction ranges from neutral through medium acid.
The Eg horizon has hue of 10YR or 2.5Y, value of 3 through 5, and chroma of 1 or 2. It is silt loam, loam, clay loam or silty clay loam. Reaction ranges from medium acid through very strongly acid.
The 2Btg horizons have hue of 5Y through 10YR, value of 4 through 6, and chroma of 1 or 2. It has higher or lower chroma mottles. The texture typically is clay or silty clay with subhorizons of clay loam or silty clay loam in some pedons. Coatings of silt or very fine sand are not in all pedons. The reaction ranges from medium acid through very strongly acid.
COMPETING SERIES: These are the
Shields and
Tuskeego series. The Shields series formed in modified lacustrine sediments containing appreciable amounts of shale and has carbonates at shallower depths. The Tuskeego series is not developed in a paleosol.
GEOGRAPHIC SETTING: Stateline soils are in shallow swales and on broad low lying flats of upland till plains. They formed in 16 to 30 inches of loess or loamy sediments and underlying clayey paleosol. The paleosol is probably Aftonian Age and formed in pedisediments and till. Slopes are less than 2 percent. The mean annual temperature is about 43 to 48 degrees F, and the mean annual precipitation is about 28 to 34 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Donnan,
Sargeant,
Skyberg, and
Brownsdale soils. Donnan soils are similar, but are better drained and are on slightly higher landscape positions. Sargeant and Skyberg soils are on slightly higher landscape positions, are better drained and do not have the clayey subsoil. Brownsdale soils are in similar position, but do not have the clayey subsoil.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is slow. Permeability is very slow.
USE AND VEGETATION: Most areas are used for cultivated crops. Corn and soybeans are the most common crops. The native vegetation was oak savannah and tall grass prairie-forest borders.
DISTRIBUTION AND EXTENT: Stateline soils are inextensive in southeastern Minnesota.
