DAIR SERIES


The Dair series consists of very deep, poorly drained or very poorly drained soils formed in sandy glaciofluvial deposits in depressions and drainageways on outwash plains, lake plains, dunes, and low beach ridges. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 787 mm (31 inches), and mean annual temperature is about 8.3 degrees C (47 degrees F).

TAXONOMIC CLASS: Mixed, mesic Typic Psammaquents

TYPICAL PEDON: Dair muck, on a 1 percent slope in a wooded area at an elevation of 244 meters (800 feet) above mean sea level. (Colors are for moist soil unless otherwise stated. When described on September 4, 1996, the soil was moist to 53 cm (21 inches) and saturated below.)

Oa--0 to 10 cm (4 inches); black (5YR 2.5/1) muck (sapric material); about 5 percent fiber, about 0 percent rubbed; weak thick platy structure parting to weak fine granular; very friable; many fine to coarse roots throughout; moderately acid; clear wavy boundary. [10 to 20 cm (4 to 8 inches) thick]

A--10 to 18 cm (4 to 7 inches); very dark gray (2.5Y 3/1) mucky sandy loam, very dark grayish brown (2.5Y 3/2) dry; weak medium and fine granular structure; very friable; many fine and medium roots throughout; slightly acid; abrupt smooth boundary. [0 to 8 cm (3 inches) thick]

Bw--18 to 28 cm (7 to 11 inches); brownish yellow (10YR 6/6) sand; weak coarse subangular blocky structure; very friable; few fine interstitial pores; common fine and medium faint yellowish brown (10YR 5/6) masses of oxidized iron in the matrix; about 1 percent gravel; neutral; abrupt smooth boundary. [10 to 20 cm (4 to 8 inches) thick]

C--28 to 53 cm (11 to 21 inches); light olive brown (2.5Y 5/3) sand; weak coarse subangular blocky structure; very friable; about 1 percent gravel; slightly alkaline; clear wavy boundary.

Cg1--53 to 127 cm (21 to 50 inches); grayish brown (2.5Y 5/2) sand; single grain; loose; about 1 percent gravel; slightly alkaline; abrupt smooth boundary.

Cg2--127 to 203 cm (50 to 80 inches); dark grayish brown (2.5Y 4/2) sand; single grain; loose; streaks of black (10YR 2/1) sand; about 1 percent gravel; neutral.

TYPE LOCATION: Benzie County, Michigan; 300 feet south and 50 feet east of the northwest corner of sec. 12, T. 25 N., R. 14 W., Weldon Township; USGS Thompsonville, Michigan 7.5 minute topographic quadrangle; lat. 44 degrees 35 minutes 04 seconds N. and long. 85 degrees 57 minutes 26 seconds W., NAD 83.

COMPETING SERIES: These are the Arloval, Barren, Carrolls, Conrad, Forbar, Gothenburg, Jamaica (T), Junius, Norway, Stafford, Tihonet, Tryon, Tyre, and Wanser series. Arloval, Forbar, Norway, Tryon, and Wanser soils formed in areas that receive less than 762 mm (30 inches) of annual precipitation. Barren and Jamaica soils have anthropotransported materials within the series control section. Carrolls soils contain volcanic glass within the series control section. Conrad and Gothenburg soils do not have a B horizon. Junius soils have a B horizon that is thicker than 20 cm (8 inches). Stafford soils are more acidic than neutral in the lower part of the series control section. Tihonet series have excavated fill material within the series control section. Tyre soils have a lithic contact within a depth of 102 cm (40 inches).

GEOGRAPHIC SETTING: Dair soils are in depressions and drainageways on outwash plains, lake plains, low beach ridges, and dunes. Slope ranges from 0 to 2 percent. These soils formed in sandy glaciofluvial deposits. Mean annual precipitation ranges from 762 to 813 mm (30 to 32 inches). Mean annual temperature ranges from 7.2 to 9.4 degrees C (45 to 49 degrees F). Frost-free period is 120 to 160 days. Elevation is 183 to 305 meters (600 to 1000 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Saugatuck, Brethren, Benzonia, Kaleva, and Grattan soils. The somewhat poorly drained Saugatuck soils, the moderately well drained Brethren soils, the somewhat excessively drained Benzonia soils, and the excessively drained Kaleva and Grattan soils are in a drainage sequence with the Dair soils.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained or very poorly drained. Depth to the top of an apparent seasonal high water table ranges from 30 cm (1.0 foot) above the surface to 30 cm (1.0 foot) below for much of the year in normal years. Potential for surface runoff is negligible. Saturated hydraulic conductivity is high or very high. Permeability is rapid.

USE AND VEGETATION: Most areas are forested. Native vegetation is aspen, red maple, alder, northern white cedar, and dogwoods.

DISTRIBUTION AND EXTENT: MLRA 96 in northwestern Lower Peninsula of Michigan. The series is of moderate extent.

SERIES ESTABLISHED: Benzie County, Michigan, 2005.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 18 cm (7 inches) (Oa, A horizons).
Aquic conditions: from 4 to 80 inches (A, Bw, C, Cg1 and Cg2 horizons). The matrix colors result from uncoated sand grains.
