MOUNDVILLE SERIES

The Moundville series consists of very deep, moderately well drained soils formed in sandy deposits on stream terraces and outwash plains. Slope ranges from 0 to 6 percent. Mean annual precipitation is about 737 mm (29 inches). Mean annual air temperature is about 8.3 degrees C (47 degrees F).

TAXONOMIC CLASS: Sandy, mixed, mesic Oxyaquic Hapludalfs

TYPICAL PEDON: Moundville loamy fine sand - on a 2 percent slope in a cultivated field at an elevation of about 240 meters (788 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 18 cm (0 to 7 inches); very dark brown (10YR 2/2) and very dark grayish brown (10YR 3/2) loamy fine sand, light brownish gray (10YR 6/2) dry; weak fine granular structure; very friable; neutral; abrupt smooth boundary. [15 to 23 cm (6 to 9 inches) thick]

Bt1--18 to 46 cm (7 to 18 inches); brown (7.5YR 4/4) loamy fine sand; weak fine granular structure; very friable; clay bridging between sand grains; strongly acid; clear smooth boundary. [20 to 31 cm (8 to 12 inches) thick]

Bt2--46 to 61 cm (18 to 24 inches); brown (7.5YR 4/4) loamy fine sand; weak fine and medium subangular blocky structure; very friable; clay bridging between sand grains; strongly acid; clear smooth boundary. [15 to 25 cm (6 to 10 inches) thick]

BC--61 to 81 cm (24 to 32 inches); brown (7.5YR 4/4) loamy fine sand; weak medium subangular blocky structure; very friable; common fine distinct strong brown (7.5YR 5/6) masses of oxidized iron in the matrix; strongly acid; gradual smooth boundary. [15 to 25 cm (6 to 10 inches) thick]

C1--81 to 107 cm (32 to 42 inches); brown (7.5YR 5/4) fine sand; single grain; loose; many fine distinct strong brown (7.5YR 5/8) masses of oxidized iron in the matrix; strongly acid; gradual smooth boundary. [13 to 38 cm (5 to 15 inches) thick]

C2--107 to 152 cm (42 to 60 inches); yellowish brown (10YR 5/6) fine sand; single grain; loose; common fine and medium distinct yellowish brown (10YR 5/8) and strong brown (7.5YR 5/8) masses of oxidized iron in the matrix; strongly acid.

TYPE LOCATION: Marquette County, Wisconsin; about 6 miles east of Briggsville; 1,136 feet west and 250 feet north of the southeast corner of sec. 30, T. 14 N., R. 9 E. USGS Endeavor Wisconsin Quadrangle; lat. 43 degrees 39 minutes 28 seconds N., and long. 89 degrees 28 minutes 8 seconds W., NAD 27.

RANGE IN CHARACTERISTICS:
Solum thickness: 66 to 102 cm (26 to 40 inches)
Rock fragments: typically absent but volume of gravel ranges up to 2 percent in some pedons
Reaction: naturally slightly acid to strongly acid in the solum, neutral in the upper part, where the soil is limed;
strongly acid to neutral in the substratum
Redox accumulations and saturation: within 102 cm (40 inches) for one month or more per year in 6 or more out of 10 years.

COMPETING SERIES: There are no competing series.

GEOGRAPHIC SETTING: Moundville soils are on stream terraces and outwash plains. Slope ranges fron 0 to 6 percent. These soils formed in thick loamy sand or sand deposits. Mean annual precipitation ranges from 635 to 889 mm (25 to 35 inches). Mean annual air temperature ranges from 7.2 to 11.1 degrees C (45 to 52 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dakota, Gotham, Meridian, Plainfield, and Sparta soils. The Dakota and Meridian soils are nearby in areas where there is a 51 to 102 cm (20 to 40 inches) thick loamy mantle. Gotham soil are in higher landscape positions where there is no water table. Plainfield and Sparta soils are on similar landscape positions where there is no argillic horizon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. The potential for surface runoff ranges from negligible to low. Saturated hydraulic conductivity is high to very high (42.34 to 141.14 micrometers per second). Permeability is rapid. These soil have an apparent seasonal high water table at a depth of 61 to 76 cm (2 to 2.5 feet) for one month or more per year in 6 or more out of 10 years.

USE AND VEGETATION: Most areas have been cleared and are used for cropland. Common crops are corn, small grain, and hay. Native vegetation is mixed prairie grasses with deciduous and a few coniferous trees.

DISTRIBUTION AND EXTENT: MLRAs 90A, 95B, and 105 in central and southern Wisconsin. This soil is of moderate extent.
