LOCATION BURT MIEstablished Series
TAXONOMIC CLASS: Siliceous, frigid Lithic Psammaquents
TYPICAL PEDON: Burt mucky sand with a nearly level slope of 1 percent on a lake plain in a forested area. (Colors are for moist soil unless otherwise stated.)
0a--0 to 1 inches; black (10YR 2/1) muck; weak medium granular structure; friable; many fine roots; 5 percent pebbles; strongly acid; abrupt smooth boundary. (0 to 5 inches thick)
A--1 to 5 inches; black (10YR 2/1) mucky sand; gray (10YR 5/1) dry; weak medium granular structure; very friable; many fine roots; 5 percent pebbles; moderately acid; abrupt smooth boundary. (2 to 6 inches thick)
Cg--5 to 13 inches; gray (5Y 5/1) sand; single grain; loose; few fine roots; 5 percent pebbles; moderately acid; clear smooth boundary. (6 to 12 inches thick)
C--13 to 19 inches; brown (10YR 5/3) sand; single grain; loose; no roots; 5 percent pebbles; slightly acid; abrupt clear boundary. (0 to 12 inches thick)
2R--19 inches; brown (10YR 5/3) sandstone bedrock.
TYPE LOCATION: Baraga County, Michigan; 700 feet south and 2,640 feet east of the northwest corner of sec. 27, T. 52 N., R. 33 W.
RANGE IN CHARACTERISTICS: Depth to the lithic contact ranges from 10 to 20 inches. The pedon ranges from very strongly acid to slightly acid. Rock fragments consisting mainly of sandstone, pebbles, channers, and flags range from 0 to 30 percent. Gravel and cobbles range from 0 to 5 percent.
The Oa horizon has hue of 5YR to 10YR, or is neutral; value of 2 or 3 and chroma of 1 or 2.
The A horizon has hue of 10YR, 7.5YR, or 5YR; value of 2 or 3; chroma of 0 or 1. It is mucky fine sand, mucky sand, mucky loamy sand, fine sand, sand, or loamy sand.
The C horizon has hue of 10YR, 2.5Y, or 5Y; value of 4 to 7; and chroma of 1 to 3. It is fine sand, sand, loamy sand, or loamy fine sand, or channery analogues of these textures.
COMPETING SERIES: There are none. Closely related series include Kawbawgam, Nahma, and Ruse. Kawbawgam and Nahma soils are coarse-loamy and have limestone bedrock at depths of 20 to 40 inches. Ruse soils are finer textured, less acid, and are underlain by limestone bedrock.
GEOGRAPHIC SETTING: Burt soils are on nearly level parts or in depressions of lake plains and on seepy slopes of sandstone benches. Slopes range from 0 to 3 percent. The mean annual precipitation ranges from 26 to 33 inches, the mean annual temperature from 41 to 44 degrees F, and the mean summer temperature ranges from 60 to 65 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: The well drained Deerton and Onota soils and the moderately well drained Munising soils are adjacent on higher landscape positions. Tawas soils are organic soils found in similar landscape positions.
DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is negligible. Permeability is rapid in the solum, but downward movement of water is impeded by the bedrock.
USE AND VEGETATION: Burt soils are used for woodland. Vegetation is alder, aspen, balsam fir, black spruce, hemlock, red maple, and white cedar.
DISTRIBUTION AND EXTENT: Upper Peninsula of Michigan. The series is of small extent.
