PUCHYAN SERIES


The Puchyan series consists of very deep, moderately well drained soils formed in a mantle of sandy eolian deposits; in the underlying loamy transition layer; and in loess or other silty deposits underlain by loamy till on moraines. Slope ranges from 2 to 12 percent. Mean annual precipitation is about 787 mm (31 inches). Mean annual air temperature is about 8.9 degrees C (48 degrees F).

TAXONOMIC CLASS: Loamy, mixed, superactive, mesic Arenic Oxyaquic Hapludalfs

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Puchyan soils are on moraines in association with soils formed in glacial till. Slope ranges from 2 to 12 percent. Puchyan soils formed in sandy eolian deposits, in a loamy transition layer, and in loess or other silty deposits which, in turn, are underlain by loamy glacial till. Mean annual precipitation ranges from 711 to 813 mm (28 to 32 inches). Mean annual air temperature ranges from 7.2 to 11.3 degrees C (45 to 53 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Kidder, Mchenry, and Dodge soils. Puchyan soils are on gently sloping or sloping areas in the upland near the well drained Miami, McHenry, and Dodge soils. These soils are in areas where there is a silty mantle.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. The potential for surface runoff is low or very low. Saturated hydraulic conductivity is high to very high (42.34 to 141.14 micrometers per second) in the sandy mantle and moderately high to high (4.23 to 14.11 micrometers per second) in the underlying deposits. Permeability is rapid in the sandy mantle and moderate in the underlying deposits. These soils have a perched seasonal high water table within a depth of 102 cm (40 inches) for one month or more per year in 6 or more out of 10 years.

USE AND VEGETATION: Most areas of these soils are used for cropland. Common crops are corn, small grains, and hay , as well as canning crops such as snap beans, peas, and sweet corn. Native vegetation is deciduous forest. Common trees are black oak, bur oak, and hickory.

DISTRIBUTION AND EXTENT: MLRAs 95A, and 95B in south-central Wisconsin. The Puchyan soils are of small extent.

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

SERIES ESTABLISHED: Columbia County, Wisconsin, 1972.

REMARKS: This soil formerly was called Rio and later, Columbus series.

11/04 5400 acres have been correlated in three surveys. The typical pedons in all three surveys have redox features above 40 inches. Therefore, this revision changes the concept of th series to moderately well drained only (Arenic Oxyaquic Hapludalfs).

Diagnostic horizons and features recognized in this pedon are: Ochric epipedon - 0 to 23 cm (0 to 9 inches) (Ap); Argillic horizon - 69 to 117 cm (27 to 46 inches) (2Bt1, 2Bt2, and 3Bt3); Arenic feature - loamy fine sand or coarser in all horizons from the soil surface to the top of the argillic at a depth of 69 cm (27 inches) (Ap, Bw1, Bw2); oxyaquic feature redox accumulations and saturation within a depth of 102 cm (40 inches).
