MUNUSCONG SERIES

The Munuscong series consists of very deep, poorly drained and very poorly drained soils formed in loamy glaciofluvial deposits over calcareous clayey materials on lake plains and ground moraines. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 762 mm (30 inches), and mean annual temperature is about 6.7 degrees C (44 degrees F).

TAXONOMIC CLASS: Coarse-loamy over clayey, mixed, active, nonacid, frigid Mollic Epiaquepts

TYPICAL PEDON: Munuscong fine sandy loam, on a 1 percent slope on a till plain in a pastured area. (Colors are for moist soil unless otherwise stated).

A--0 to 20 cm (8 inches); black (10YR 2/1) fine sandy loam, dark grayish brown (10YR 4/2) dry; weak fine granular structure; friable; many fine roots; slightly acid; abrupt smooth boundary. [15 to 23 cm (6 to 9 inches) thick]

Bg1--20 to 41 cm (8 to 16 inches); dark gray (10YR 4/1) sandy loam; weak medium subangular blocky structure; friable; common fine roots; many medium prominent yellowish red (5YR 4/6) and brownish yellow (10YR 6/6) masses of oxidized iron; neutral; gradual wavy boundary. [15 to 33 cm (6 to 13 inches) thick]

Bg2--41 to 76 cm (16 to 30 inches); gray (10YR 5/1) sandy loam; weak medium subangular blocky structure; friable; few fine roots; common medium faint grayish brown (10YR 5/2) iron depletions; common medium prominent yellowish brown (10YR 5/6) masses of oxidized iron; slightly alkaline; abrupt smooth boundary. [20 to 46 cm (8 to 18 inches) thick]

2Cg--76 to 152 cm (30 to 60 inches); reddish gray (5YR 5/2) silty clay; massive; firm; common medium distinct brown (7.5YR 4/4) masses of oxidized iron; slightly effervescent; moderately alkaline.

TYPE LOCATION: Osceola County, Michigan; about 1 1/2 miles southwest of village of Sears; 420 feet east and 340 feet south of the center of sec. 7, T. 17 N., R. 7 W.

COMPETING SERIES: There are no other series in the same family.

GEOGRAPHIC SETTING: Munuscong soils are on lake plains and ground moraines. Slope ranges from 0 to 2 percent. Munuscong soils formed in loamy glaciofluvial deposits over calcareous clayey materials. Mean annual precipitation ranges from 711 to 1016 mm (28 to 40 inches). Mean annual temperature ranges from 5.6 to 8.3 degrees C (42 to 47 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Isabella, Nester, Pinconning, and Sims soils. The well drained, finer textured Isabella soils and the moderately well drained Nester soils are on higher landscape positions adjacent to the Munuscong soils. The coarser textured Pinconning soils and the finer textured Sims soils are on similar landscape positions.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained or very poorly drained. The potential for surface runoff is negligible to very high. Saturated hydraulic conductivity is high in the solum and moderately low in the substratum. Permeability is moderately rapid in the solum and slow in the substratum.

USE AND VEGETATION: Most areas of these soils are in pasture or forest. Native vegetation is black ash, northern whitecedar, white spruce, balsam fir, tamarack, paper birch, and red maple. A few areas are under cultivation. Small grains, grass-alfalfa hay, and beans are the principal crops.

DISTRIBUTION AND EXTENT: MLRAs 92, 93B, 94A, 96, 98, and 142 in central and northern Michigan and northern New York. This series is of small extent.
