NICHOLS SERIES


The Nichols series consists of very deep, moderately well drained soils formed in mostly loamy stratified lacustrine deposits on glacial lake basins. Slope ranges from 0 to 25 percent. Mean annual precipitation is about 762 mm (30 inches). Mean annual air temperature is about 8.3 degrees C (47 degrees F).

TAXONOMIC CLASS: Coarse-silty, mixed, superactive, mesic Oxyaquic Eutrudepts

[Combined thickness of the Bw horizon ranges from 31 to 79 cm (12 to 31 inches).]

C--66 to 203 cm (26 to 80 inches); yellowish brown (10YR 5/4) and brown (7.5YR 5/4) stratified very fine sandy loam, silt, silt loam, and silty clay loam with a few very thin strata of silty clay; massive breaking to weak thick plates along depositional strata; very friable; common fine and medium distinct and prominent yellowish brown (10YR 5/8) and strong brown (7.5YR 5/6) masses of oxidized iron in the matrix; very few fine prominent black (N 2.5/) irregular masses of iron-manganese in the matrix; violently effervescent; moderately alkaline.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: These soils are on glacial lake basins. Slopes range from 0 to 25 percent. These soils formed mostly in very fine sandy loam or silt loam lacustrine deposits. Mean annual precipitation ranges from 635 to 890 mm (25 to 35 inches). Mean annual air temperature ranges from 7.8 to 8.9 degrees C (46 to 48 degrees F). Elevation ranges from 198 to 291 meters (650 to 985 feet) above mean sea level. The frost-free period ranges from 120 to 135 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Boyer, Grays, Keowns, and Shiocton series. The well drained Boyer soils are on nearby outwash plains where there is less silt and more sand in the subsoil. The moderately well drained Grays soils are on similar landscape positions where there is more clay and less silt in the subsoil. The somewhat poorly drained Shiocton soils are on slightly lower landscape positions. The poorly drained Keowns soils are on lower landscape positions.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. The potential for surface runoff ranges from negligible to high. Saturated hydraulic conductivity is moderately high to high (4.23 to 14.11 micrometers per second). Permeability is moderate. These soils have an apparent seasonal high water table at a depth of 46 to 91 cm (1.5 to 3 feet) for one month or more per year in 6 or more out of 10 years.

USE AND VEGETATION: Most areas are used for cropland. Common crops are corn, small grains soybeans, and hay. Specialty crops such as green beans, cabbage, peas, and sweet corn, are also grown. Some areas are used for pastureland or woodland. Native vegetation is maple-basswood forest.

DISTRIBUTION AND EXTENT: MLRA 95A (Eastern Wisconsin Till Plain). Nichols soils are of moderate extent (21,086 acres correlated).

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Indianapolis, Indiana.

SERIES ESTABLISHED: Outagamie County, Wisconsin, 1975. Name comes from a small village in the county.

REMARKS: Diagnostic horizons and features recognized in this pedon are: ochric epipedon - 0 to 20 cm (0 to 8 inches)(Ap); cambic horizon - 20 to 66 ccm (8 to 26 inches) (Bw1, Bw2, Bw3); oxyaquic feature - redox accumulations and saturation within 102 cm (40 inches).

This soil series was originally established in Outagamie County Wisconsin in 1975. It was later correlated in Calumet and Manitowoc Counties in 1976 and in Kewaunee County in 1977. The series was made inactive about 1987. The series site location was revisited in June 2006 and described to 80 inches. Since 11,292 acres in Outagamie County are moderately well drained and 9479 acres in the Calumet-Manitowoc survey are described as well drained and moderately well drained but have a moderately well drained TUD, the series concept is changed to moderately well drained (Oxyaquic) with this revision. A new series may be needed for 315 well drained acres in Kewaunee Co. and any well drained acres in Calumet and Manitowoc Counties.

Since all of Calumet Kewaunee and Manitowoc counties are in the mesic temperature area and about 98% of Outagamie County (including all the acres of Nichols) is mesic, the temperature regime is changed to mesic in this revision.

Additional field and laboratory study is needed to verify the family texture and the presence or absence of an argillic horizon. About 2180 acres of similar soil on the same landform in Shawano County were correlated as coarse-loamy, argillic Salter Variant.

An additional 980 acres of this soil were correlated in Outagamie County as a clayey substratum phase. A new series may be needed for these acres.
