LOCATION LUMLEY MIEstablished Series
TAXONOMIC CLASS: Dysic, mesic Typic Haplosaprists
TYPICAL PEDON: Lumley peat - on a level area in a cultivated field. (Colors are for moist soils unless otherwise stated. When described on Oct. 24, 1997, the soil was moist to a depth of 12 inches and saturated below.)
Oi1--0 to 3 inches; dark yellowish brown (10YR 4/4) broken face and brown (7.5YR 4/4) rubbed peat (fibric material); about 100 percent fiber, about 75 percent rubbed; strong fine and medium platy structure; very friable; few fine and coarse roots; extremely acid; abrupt smooth boundary.
Oi2--3 to 6 inches; dark brown (7.5YR 3/3) broken face, very dark brown (7.5YR 2.5/3) rubbed muck (fibric material); about 80 percent fiber, about 75 percent rubbed; strong fine and medium platy structure; very friable; few fine roots; extremely acid; abrupt smooth boundary.
Oa1--6 to 8 inches; black (10YR 2/1) broken face and rubbed muck (sapric material); about 20 percent fiber, about 10 percent rubbed; moderate coarse granular structure; very friable; few fine roots; extremely acid; abrupt smooth boundary.
Oa2--8 to 20 inches; dark brown (7.5YR 3/3) broken face, very dark brown (7.5YR 2.5/3) rubbed muck (sapric material); about 30 percent fiber, about 10 percent rubbed; weak fine and medium platy structure; very friable; extremely acid; abrupt smooth boundary.
Oa3--20 to 45 inches; dark brown (7.5YR 3/3) broken face and rubbed muck (sapric material); about 20 percent fiber, about 5 percent rubbed; weak fine and medium platy structure; extremely acid; abrupt smooth boundary.
Oa4--45 to 53 inches; very dark brown (7.5YR 2.5/3) broken face and rubbed muck sapric material); about 40 percent fiber, about 10 percent rubbed; weak fine and medium platy structure; extremely acid; abrupt smooth boundary.
Oa5--53 to 80 inches; very dark gray (10YR 3/1) broken face and black (10YR 2/1) rubbed muck (sapric material); about 5 percent fiber, unrubbed and rubbed; weak fine and medium platy structure; extremely acid; abrupt smooth boundary.
TYPE LOCATION: Manistee County, Michigan; about 2 miles northwest of the village of Bear Lake; 1800 feet south and 200 feet east of the northwest corner, sec. 31, T. 24 N., R. 15 W., Pleasanton Township; USGS Bear Lake, Michigan 7.5 minute topographic quadrangle; lat. 44 degrees 26 minutes 28 seconds N. and long. 86 degrees 10 minutes 53 seconds W., NAD 83.
RANGE IN CHARACTERISTICS: The organic layers are more than 51 inches thick.
The organic fibers are derived primarily from herbaceous plants. The woody fragment content averages less than 15 percent by volume in the control section. Reaction is ultra acid to extremely acid.
The organic layers have hue of 5YR to 10YR, value of 2 to 4, and chroma of 1 to 4. The layers are predominantly sapric material, but in some pedons hemic and fibric materials have a combined thickness of less than 10 inches.
COMPETING SERIES: These are the
Pangborn,
Puckum, and
Freetown series. The
Pangborn soils formed in areas with a marine climate and have a difference in mean summer temperature and mean winter temperature of less than 16 degrees F. The Puckum soils formed in nonglaciated areas and have a mean annual temperature of more than 50 degrees F. The Freetown soils have a mean annual temperature of more than 45 degrees F.
GEOGRAPHIC SETTING: Lumley soils occupy closed depressions on lake plains,
outwash plains, ground and end moraines. Slope gradients are less than 2 percent. Elevations are 600 to 1000 feet. The mean annual precipitation ranges from about 30 to 32 inches and the mean annual temperature is about 45 to 48 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Brethren,
Kaleva,
Copemish, and
Makinen. The Brethren, Kaleva and Copemish soils are sandy and are on associated uplands. The Makinen soils are in nearby depressions and at the margin of the depressions where the organic deposits are shallower.
DRAINAGE AND PERMEABILITY: Very poorly drained. Depth to the seasonal high
water table ranges from 1 foot above the surface to 1 foot below the surface from September to June. The potential surface runoff is low or negligible. Permeability is moderately slow to moderately rapid.
USE AND VEGETATION: Most of this soil is in native vegetation. Native trees include tamarack, black spruce, and white pine. Understory vegetation includes leatherleaf, cranberries, sphagnum moss, cotton grass, bog rosemary, blueberries, and pitcher plants.
DISTRIBUTION AND EXTENT: Northwestern part of the lower peninsula of Michigan.
The series is of small extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana
SERIES ESTABLISHED: Manistee County, Michigan, 1998.
REMARKS: Diagnostic horizons and features recognized in this pedon are: partially and well decomposed organic material from the surface to greater than 51 inches (Oi1, Oi2, Oa1, Oa2, Oa3, Oa4, and Oa5 horizons).
