PRINSBURG SERIES


The Prinsburg series consists of very deep, poorly drained soils that formed in calcareous, silty lacustrine sediments overlying calcareous, loamy glacial till on ground moraines. The permeability is moderate. Slope ranges from 0 to 2 percent. Mean annual air temperature is about 46 degrees F. Mean annual precipitation is about 27 inches.

TAXONOMIC CLASS: Fine-silty, mixed, superactive, calcareous, mesic Typic Endoaquolls

TYPICAL PEDON: Prinsburg silty clay loam, on a slope of 1 percent, on a ground moraine, in a cultivated field. (Colors are for moist soil unless otherwise noted.)

Ap--0 to 8 inches; black (N 2/0) silty clay loam, black (10YR 2/1) dry; weak medium granular structure; friable; common fine roots; slightly effervescent; slightly alkaline; abrupt smooth boundary.

A--8 to 19 inches; black (10YR 2/1) silty clay loam, dark gray (10YR 4/1) dry; weak fine and medium subangular blocky structure; friable; few fine roots; strongly effervescent; moderately alkaline; clear smooth boundary. (Combined thickness of the A horizon is 12 to 24 inches.)

Bkg--19 to 29 inches; grayish brown (2.5Y 5/2) silt loam; weak medium subangular blocky structure; friable; few fine prominent light yellowish brown (2.5Y 6/4) Fe concentrations; few fine roots; disseminated carbonates; violently effervescent; moderately alkaline; clear smooth boundary. (0 to 16 inches thick)

Bg--29 to 36 inches; dark grayish brown (2.5Y 4/2) silt loam; weak medium subangular blocky structure; friable; few fine prominent yellowish brown (10YR 5/6) Fe concentrations; few fine roots; strongly effervescent; slightly alkaline; gradual wavy boundary. (10 to 20 inches thick)

Cg1--36 to 46 inches; grayish brown (2.5Y 5/2) silt loam; massive; friable; common medium prominent yellowish brown (10YR 5/8) Fe concentrations; strongly effervescent; slightly alkaline; gradual wavy boundary. (0 to 10 inches thick)

2Cg2-- 46 to 80 inches; grayish brown (2.5Y 5/2) clay loam; massive; friable; common fine prominent olive brown (2.5Y 4/4) Fe concentrations; about 7 percent gravel; strongly effervescent; slightly alkaline; gradual wavy boundary.

TYPE LOCATION: Renville County, Minnesota; about 6 miles north and 1.5 miles west of Renville; located about 175 feet north and 1,600 feet west of the southeast corner of section 1, T. 116 N., R. 37 W.; USGS Prinsburg topographic quadrangle; lat. 44 degrees 52 minutes 36 seconds N and long. 95 degrees 14 minutes 46 seconds W., NAD 83.

RANGE IN CHARACTERISTICS: The mollic epipedon ranges from 12 to 24 inches in thickness. Calcium carbonates are in all parts between 10 and 20 inches. The calcium carbonate equivalent typically ranging from 5 to 25 percent throughout, however, the Ap horizon may be leached in some pedons. The thickness of the upper sediment and depth to glacial till ranges from 40 to 60 inches. Some pedons have calcic horizons below a depth of 16 inches. Reaction is slightly alkaline or moderately alkaline throughout. The upper mantle typically does not have rock fragments and averages less than 15 percent fine sand and coarser. Rock fragments, of mixed lithology, range from 2 to 10 percent by volume in the underlying glacial till.

The A horizon has hue of 10YR or is neutral, value of 2 or 3, and chroma of 0 or 1. It is silty clay loam or silt loam.

The Bkg and Bg horizons have hue of 2.5Y or 5Y, value of 4 or 5 and chroma of 1 or 2. It is silty clay loam or silt loam.

The Cg horizon has hue of 2.5Y or 5Y, value of 5 or 6, and chroma of 1 to 4. It is silt loam or silty clay loam.

The 2Cg horizon has hue of 2.5Y or 5Y, value of 5 or 6 and chroma of 1 to 4. It is loam or clay loam. The content of fine sand and coarser ranges from 20 to 40 percent

COMPETING SERIES: These are the Calcousta and Spicer series. Calcousta and Spicer soils do not have 2C horizons with greater than 20 percent fine sand or coarser within 60 inches of the soil surface.

GEOGRAPHIC SETTING: Prinsburg soils have linear, slightly concave or slightly convex slopes on level to nearly level ground moraines. Slope ranges from 0 to 2 percent. These soils formed in calcareous, silty lacustrine sediments overlying calcareous, loamy glacial till. These sediments are late Wisconsin in age. Mean annual air temperature ranges from 45 to 48 degrees F. Mean annual precipitation ranges from 25 to 30 inches. Frost-free period ranges from 124 to 155 days. Elevation ranges from 1,000 to 1,125 feet above sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These include the Chetomba, Doland, Quam, and Tara soils. Chetomba soils are poorly drained and are on similar landscape positions, but are not calcareous throughout. Doland soils are well drained and are on higher back slopes and summits. Quam soils are very poorly drained and are in closed depressions. Tara soils are moderately well drained and are on low back slopes or summits.

DRAINAGE AND PERMEABILITY: Poorly drained. Surface runoff is slow. Permeability is moderate. The apparent seasonal high water table is at .5 to 1.5 feet at some time during November to June in normal years.

USE AND VEGETATION: Most areas are cultivated with corn and soybeans the principal crops. Native vegetation is a wet-site community of the tall grass prairie.

DISTRIBUTION AND EXTENT: South central Minnesota. Moderately extensive.

SERIES ESTABLISHED: Renville County, Minnesota, 1995.

REMARKS: Diagnostic horizons and features recognized in this pedon include: mollic epipedon - the zone from the surface of the soil to a depth of 19 inches (Ap and A horizons); cambic horizon - the zone from 19 to 36 inches (Bkg and Bg horizons); aquic moisture condition - low chroma immediately below the mollic epipedon and redoximorphic concentrations; calcareous family - calcium carbonate throughout.
