LOCATION KANARANZI MNEstablished Series
TAXONOMIC CLASS: Fine-loamy over sandy or sandy-skeletal, mixed, superactive, mesic Typic Hapludolls
TYPICAL PEDON: Kanaranzi silt loam, on a slightly convex slope of 1 percent, on a glacial outwash plain, in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 7 inches; very dark brown (10YR 2/2) silt loam, very dark grayish brown (10YR 3/2) dry; weak fine subangular blocky structure; friable; slightly acid; abrupt smooth boundary. (6 to 10 inches thick)
BA--7 to 12 inches; dark brown (10YR 3/3) loam, brown (10YR 4/3) dry; very dark grayish brown (10YR 3/2) coats on faces of peds; weak fine prismatic structure parting to weak fine and medium subangular blocky; friable; slightly acid; clear wavy boundary. (0 to 7 inches thick)
Bw--12 to 20 inches; brown (10YR 4/3) loam, very dark grayish brown (10YR 3/2) coats on faces of peds; weak medium prismatic structure; friable; slightly acid in upper part grading to neutral in lower part; clear wavy boundary. (4 to 12 inches thick)
2C1--20 to 26 inches; brown (10YR 4/3) mixed with grayish brown (10YR 5/2) gravelly coarse sand; single grain; loose; about 20 percent coarse fragments; slightly effervescent; slightly alkaline; clear wavy boundary. (0 to 8 inches thick)
2C2--26 to 50 inches; mixed gray (10YR 5/1) and yellowish brown (10YR 5/4) gravelly coarse sand; single grain; loose; about 20 percent coarse fragments; strongly effervescent; slightly alkaline; clear smooth boundary. (0 to 20 inches thick)
2C3--50 to 80 inches; yellowish brown (10YR 5/4) gravelly coarse sand; single grain; loose; about 20 percent gravel; strongly effervescent; slightly alkaline.
TYPE LOCATION: Nobles County, Minnesota; located about 200 feet south and 200 feet east of northwest corner of section 5, T. 103 N., R. 43 W.; USGS Kenneth topographic quadrangle; lat. 43 degrees 45 minutes 39 seconds N. and long. 96 degrees 01 minutes 57 seconds W.; NAD 83.
RANGE IN CHARACTERISTICS: The depth to carbonates ranges from 16 to 28 inches. Depth to the coarse-textured 2C horizon ranges from 14 to 22 inches. The mollic epipedon ranges from 7 to 14 inches in thickness. The upper mantle has less than 5 percent by volume of gravel. The underlying material has 10 to 50 percent gravel. The A and B horizons typically range from 18 to 32 percent clay.
The A horizon has hue of 10YR, value of 2 or 3, and chroma of 1 or 2. It is loam, silt loam, or clay loam. It typically ranges from slightly acid to neutral.
The BA horizon has hue of 10YR, value of 3 and chroma of 3 or 4. It is loam, silt loam, or clay loam. It typically ranges from slightly acid to neutral.
The Bw horizon has hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 or 4. It typically is loam, silt loam, or clay loam, but the fine earth fraction of the lower 5 inches of this horizon in some pedons is sandy loam or loamy sand. The Bw horizon typically ranges from slightly acid to neutral in the upper part and neutral to slightly alkaline in the lower part.
A thin 2BC horizon is in some pedons.
Some pedons have a 2Bk horizon characterized by having calcium carbonate coats on the bottom of pebbles.
The 2C horizon has hue of 10YR, value of 4 to 6, and chroma of 1 to 4. It commonly contains several colors in a variegated pattern. It is sand, coarse sand or gravelly analogues averaging between 10 and 35 percent gravel. Some subhorizons have up to 50 percent gravel. It ranges from slightly alkaline to moderately alkaline and has carbonates.
COMPETING SERIES: These are the Cott, Fairhaven, Vanpetten, Wadena and Waukee series. The Cott, Fairhaven, Wadena and Waukee soils have an upper loamy mantle more than 24 inches thick. The Vanpetten soils have loamy glacial till above depths of 60 inches.
GEOGRAPHIC SETTING: The Kanaranzi soils are on plane to slightly convex positions on outwash plains and valley trains. Slope gradients are 0 to 15 percent. The Kanaranzi soils formed in a mantle of loamy glacial outwash 14 to 24 inches thick overlying calcareous sandy and gravelly sediments. These deposits are Late Wisconsinan in age. Mean annual air temperature is about 45 to 52 degrees F. Mean annual precipitation is about 26 to 32 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: The main ones are the Biscay, Salida, and Wadena soils. The Biscay soils are poorly drained and are on lower lying positions. The Salida soils are excessively drained and are on higher lying or more sloping terrain. The well drained Wadena soils are on terrain similar to that of the Kanaranzi series.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is low or medium. Permeability is moderate in upper mantle and rapid in underlying material.
USE AND VEGETATION: Largely cropped to corn and soybeans. Native vegetation is tall grass prairie.
DISTRIBUTION AND EXTENT: Southern Minnesota and northern Iowa. Moderately extensive.
MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Nobles County, Minnesota, 1970.
REMARKS: Diagnostic horizons and features recognized in this pedon include: mollic epipedon - from the surface of the soil to a depth of 12 inches (Ap and BA horizons); cambic horizon - the zone from about 12 to 20 inches (Bw horizon); udic moisture regime.
Surface texture changed to silt loam from loam based on a field visit to the OSD pedon location.
