MISTEGUAY SERIES

The Misteguay series consists of very deep, poorly drained soils on flood plains that occur on lake plains. They formed in clayey alluvium over clayey glaciolacustrine deposits. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 813 mm (32 inches), and mean annual temperature is about 8.9 degrees C (48 degrees F).

TAXONOMIC CLASS: Fine, mixed, semiactive, calcareous, mesic Aeric Endoaquepts

TYPICAL PEDON: Misteguay silty clay, on a 1 percent slope in a cultivated field at an elevation of 179 meters (587 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 20 cm (0 to 8 inches); dark grayish brown (2.5Y 4/2) silty clay, gray (2.5Y 6/1) dry; weak medium granular structure; friable; few white (10YR 8/1) snail shells; slightly effervescent; moderately alkaline; abrupt smooth boundary.

A--20 to 30 cm (8 to 12 inches); dark grayish brown (2.5Y 4/2) silty clay, gray (2.5Y 6/1) dry; moderate medium angular blocky structure; firm; common coarse faint dark gray (2.5Y 4/1) iron depletions; few white (10YR 8/1) snail shells; slightly effervescent; moderately alkaline; abrupt wavy boundary.

Bg--30 to 48 cm (12 to 19 inches); grayish brown (2.5Y 5/2) silty clay; weak medium subangular blocky structure; firm; common fine vesicular pores; 1 percent distinct dark grayish brown (2.5Y 4/2) organic stains on surfaces along root channels; common fine and medium prominent dark brown (7.5YR 3/2) iron-manganese nodules; common medium prominent yellowish brown (10YR 5/6) masses of oxidized iron; strongly effervescent; moderately alkaline; clear wavy boundary.

2C1--48 to 104 cm (19 to 41 inches); light olive brown (2.5Y 5/4) silty clay; moderate medium platy structure; firm; many fine and common very fine vesicular pores; distinct white (2.5Y 8/1) silt coats on all faces of peds; common fine and medium prominent dark brown (7.5YR 3/2) iron-manganese nodules; common medium distinct yellowish brown (10YR 5/6) masses of oxidized iron; strongly effervescent; moderately alkaline; gradual wavy boundary.

2C2--104 to 173 cm (41 to 68 inches); olive brown (2.5Y 4/4) silty clay; moderate thin platy fragments inherited from deposition; firm; violently effervescent; moderately alkaline; abrupt smooth boundary.

2C3--173 to 203 cm (68 to 80 inches); dark grayish brown (2.5Y 4/2) clay, light gray (2.5Y 7/2) dry; massive; very firm; violently effervescent; moderately alkaline.

TYPE LOCATION: Saginaw County, Michigan; about 6 miles west-southwest of Saginaw; about 1,350 feet south and 100 feet west of the northeast corner of sec. 9, T. 11 N., R. 3 E., Swan Creek Township; USGS Alicia topographic quadrangle; UTM Zone 16, 733964n and 4806621e, NAD83.

COMPETING SERIES: There are no competing series. A closely related soil is the Zilwaukee series. Zilwaukee soils have a mollic epipedon.

GEOGRAPHIC SETTING: The Misteguay soils are on flood plains that occur on lake plains. Slope ranges from 0 to 2 percent. Mean annual precipitation ranges from 802 to 824 mm (31.6 to 32.4 inches). Mean annual temperature ranges from 8.3 to 8.9 degrees C (47 to 48 degrees F). Frost-free period ranges from 137 to 189 days. Elevation is 175 to 186 meters (574 to 610 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Ceresco, Roundhead, Sloan and Zilwaukee soils. The Ceresco soils are coarser textured and are on slightly higher positions on the flood plains. Roundhead soils have a histic epipedon and are in shallow depressions. Sloan soils are coarser textured and are not calcareous. Zilwaukee soils have a mollic epipedon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained. Depth to the top of an apparent seasonal high water table is at or near the surface between October and June in normal years. Potential for surface runoff is negligible. Saturated hydraulic conductivity is moderately low. Permeability is slow. This soil is subject to flooding in late fall and in early spring.

USE AND VEGETATION: Most areas of Misteguay soils are cultivated. Corn, sugar beets, soybeans and small grains are the principal crops. Native vegetation is red and silver maple, swamp white oak, white ash, and alder.

DISTRIBUTION AND EXTENT: MLRA 99 in Lower Michigan. The series is of moderate extent.
