LOCATION BURLEIGH MIEstablished Series
TAXONOMIC CLASS: Sandy over loamy, mixed, active, nonacid, frigid Mollic Endoaquents
TYPICAL PEDON: Burleigh loamy sand - on a 1 percent slope in a cultivated area at an elevation of about 730 feet. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 9 inches; very dark brown (10YR 2/2) loamy sand, grayish brown (10YR 5/2) dry; weak fine granular structure; very friable; many fine roots; neutral; abrupt smooth boundary. (7 to 10 inches thick)
Cg1--9 to 32 inches; light gray (10YR 6/1) sand; common fine prominent yellowish brown (10YR 5/6) mottles; single grain; loose; many fine roots; mildly alkaline; abrupt wavy boundary. (12 to 30 inches thick)
2Cg2--32 to 60 inches; gray (10YR 5/1) stratified silt loam and very fine sand; common medium prominent yellowish brown (10YR 5/8) mottles; silt loam is massive; friable; very fine sand is single grain; loose; few fine roots; slight effervescence; mildly alkaline.
TYPE LOCATION: Gladwin County, Michigan; about 2 miles northwest of Beaverton; 495 feet south and 100 feet east of the northwest corner of sec. 2, T. 17 N., R. 2 W.
RANGE IN CHARACTERISTICS: Depth to the 2Cg horizon and free carbonates ranges from 20 to 50 inches. The reaction of the A and Cg1 horizons ranges from slightly acid to mildly alkaline. The 2Cg2 horizon is mildly alkaline or moderately alkaline.
Some undisturbed areas have thin organic layers on the surface. The A horizon, where present, has hue of 10YR or 7.5YR, value of 2, and chroma of 1 or 2. The Ap horizon has hue of 10YR or 2.5Y, value of 2 or 3, and chroma of 1 or 2. The A horizon is sand, fine sand, loamy sand, loamy fine sand or mucky analogues of these textures.
The Cg1 horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 1 or 2. It is sand, fine sand, coarse sand, loamy sand, or loamy fine sand. The 2Cg2 horizon has hue of 7.5YR to 5Y, value of 5 or 6, and chroma of 1 to 4. It is stratified silt, silt loam, fine sandy loam, very fine sandy loam, very fine sand, loamy very fine sand, and loamy fine sand with occasional strata of fine sand, sand, silty clay loam, clay or silty clay. The strata varies widely in the thickness and sequence of layers.
COMPETING SERIES: These are the Brevort, Cook, and Grygla series. Brevort, Cook, and Grygla soils formed in sandy sediments overlying loamy glacial till. In addition, Cook soils have more rock fragments throughout the pedon.
GEOGRAPHIC SETTING: The Burleigh series are on nearly level to depressed flats on broad, slightly depressed areas on lake plains, outwash plains and deltas. Slope gradients range from 0 to 2 percent. The mean annual precipitation ranges from 26 to 32 inches. The mean annual temperature ranges from 42 to 46 degrees F. The mean summer temperature ranges from 58 to 68 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bruce, Ingalls, Ocqueoc, and Roscommon soils. The Ingalls and Ocqueoc soils are closely associated in a drainage sequence with the Burleigh soils. Bruce soils, which do not have the sandy A and Cg1 horizons; and Roscommon soils, which do not have the loamy 2Cg2 horizons, are associated on some lake plains.
DRAINAGE AND PERMEABILITY: Poorly drained and very poorly drained. Surface runoff is very slow or ponded. Permeability is rapid or moderately rapid in the A and Cg horizons and moderately slow in the 2Cg horizon.
USE AND VEGETATION: Cleared areas are used for small grain and legume- grass hay. Most of these soils are in forest, permanent pasture or remain idle. The native vegetation and present vegetation includes quaking aspen, bigtooth aspen, black ash, red maple, and swamp white oak.
DISTRIBUTION AND EXTENT: The northern part of the Lower Peninsula and the Upper Peninsula of Michigan. The series is of moderate extent.
MLRA OFFICE RESPONSIBLE: St. Paul, Minnesota
SERIES ESTABLISHED: Arenac County, Michigan, 1964.
REMARKS: Classification was adjusted to agree with ST Issue #17 on 7 Sept 94 by CLG. Diagnostic horizons and features recognized in this pedon are: contrasting particle-size (sandy over loamy) contact at 32 inches; mollic intergrade - 0 to 9 inches (Ap horizon); aquic moisture regime.
