HANGAARD SERIES
The Hangaard series consists of very deep, poorly drained soils formed in outwash sediments on interbeach areas of glacial lake plains, beach ridges and outwash plains. Permeability is moderately rapid or rapid in the upper part and rapid or very rapid in the lower part. Slopes range from 0 to 2 percent. Mean annual air temperature is about 40 degrees F. Mean annual precipitation is 22 inches.
TAXONOMIC CLASS: Sandy, mixed, frigid Typic Endoaquolls
TYPICAL PEDON: Hangaard sandy loam with a plane level slope on a glacial lake plain in a cultivated field. (All colors are for moist conditions unless otherwise stated.)
Ap--0 to 10 inches; black (10YR 2/1) sandy loam, very dark gray (10YR 3/1) dry; weak medium subangular blocky structure parting to weak fine granular; very friable; few fine roots; neutral; abrupt smooth boundary.
A--10 to 15 inches; very dark grayish brown (2.5Y 3/2) loamy sand; dark brown (10YR 3/3) dry; few medium prominent dark yellowish brown (10YR 3/4) Fe concentrations; weak fine subangular blocky structure; very friable; few fine roots; neutral; clear wavy boundary. (Combined thickness of the A horizons is 7 to 20 inches)
Cg1--15 to 35 inches; light brownish gray (2.5Y 6/2) gravelly coarse sand; few medium distinct light olive brown (2.5Y 5/4) Fe concentrations; single grain; loose; 20 percent gravel; slightly effervescent; slightly alkaline; clear smooth boundary.
Cg2--35 to 48 inches; light brownish gray (2.5Y 6/2) coarse sand; few fine distinct light olive brown (2.5Y 5/4) Fe concentrations; single grain; loose; 8 percent gravel; slightly effervescent; slightly alkaline; clear smooth boundary.
Cg3--48 to 62 inches; grayish brown (2.5Y 5/2) coarse sand; few fine prominent yellowish brown (10YR 5/8) Fe concentrations; single grain; loose; 5 percent gravel; slightly effervescent; slightly alkaline; clear smooth boundary.
Cg4--62 to 71 inches; grayish brown (2.5Y 5/2) coarse sand; few medium prominent yellowish brown (10YR 5/8) Fe concentrations; single grain; loose; 5 percent gravel; slightly effervescent; slightly alkaline; clear smooth boundary.
Cg5--71 to 80 inches; light brownish gray (2.5Y 6/2) coarse sand; few fine prominent brownish yellow (10YR 6/8) Fe concentrations; single grain; loose; 12 percent gravel; slightly effervescent; slightly alkaline.
TYPE LOCATION: Polk County, Minnesota; about 7 miles east and 3 miles north of Euclid, MN. 300 feet north and 1650 feet west of the southeast corner of Sec. 1, T. 152 N., R. 46 W.; USGS Viking SW, Minnesota topographic quadrangle; lat. 48 degrees 00 minutes 29 seconds N. and lat. 96 degrees 29 minutes 20 seconds W., NAD27.
RANGE IN CHARACTERISTICS: Thickness of the mollic epipedon, and depth to the C horizon ranges from 7 to 20 inches. Depth to free carbonates ranges from 7 to 30 inches.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 2 or 3 and chroma of 1 or 2. Texture is sandy loam, fine sandy loam, coarse sandy loam, loamy coarse sand or loamy sand. With sandy surface textures, the thickness is 10 inches or more. The reaction is slightly acid to slightly alkaline.
Rock fragments make up 0 to 15 percent, by volume, of this horizon.
A Bg horizon is in some pedons. It has hue of 10YR or 2.5Y, value of 4 or 5, and chroma of 1 or 2. It typically has redox features. It is loamy fine sand or coarser. The reaction is slightly acid to slightly alkaline. Rock fragments make up 0 to 35 percent, by volume of this horizon.
The Cg horizon has 2.5Y or 5Y hue, value of 5 or 6, and chroma of 1 or 2. Texture is sand, coarse sand, gravelly sand, gravelly coarse sand. The reaction is slightly alkaline or moderately alkaline. Rock fragments make up 10 to 35 percent, by volume of the horizon. Stratified layers with fine sand or with more than 35 percent rock fragments are in some pedons.
COMPETING SERIES: These are the
Hamar,
Isan,
Isanti, and
Venlo series. Hamar, Isanti, and Venlo soils have particle-size control sections that do not contain gravel. Isan soils do not contain carbonates above a depth of 60 inches and rock fragments in the control section are less than 5 percent.
GEOGRAPHIC SETTING: These soils are on plane or slightly concave positions on glacial lake plains, beach ridges or outwash plains. Slopes range from 0 to 2 percent. The Hangaard soils formed in a thin, discontinuous, moderately coarse-textured sediment overlying coarse textured outwash. Mean annual air temperature ranges from 36 to 45 degrees F. Mean annual precipitation from 19 to 33 inches. Frost-free days range from 90 to 150 days. Elevation above sea level ranges from 675 to 1600 feet.
GEOGRAPHICALLY ASSOCIATED SOILS: The
Sandberg,
Radium, and
Syrene soils are the main ones. These soils have formed in materials similar to those of the Hangaard soils. The excessively drained Sandberg and moderately well drained Radium soils are on nearby beach ridges. Syrene soils are in similar positions but have a calcic horizon within 16 inches of the surface.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is slow. Permeability is rapid or moderately rapid in the upper part and rapid or very rapid in the lower part. Depth to an apparent seasonal high water table is as high as .5 to 1.5 feet at some time between April and July in most years.
USE AND VEGETATION: Most of this soil is used for hay and pasture. Some areas are used for pasture and hayland. Native vegetation is a wet-site community of the tall grass prairie.
DISTRIBUTION AND EXTENT: Northwestern Minnesota, within the Glacial Lake Agassiz Plain. It is moderate in extent.
