LOCATION PINNEBOG MI+OH VT NYEstablished Series
TAXONOMIC CLASS: Euic, mesic Hemic Haplosaprists
TYPICAL PEDON: Pinnebog muck - on a level area in a forested bog.
Oa1--0 to 16 inches; black (10YR 2/1) broken face and rubbed sapric material; about 15 percent fiber, less than 5 percent rubbed; weak medium granular structure; friable; primarily herbaceous fibers; slightly alkaline; gradual smooth boundary.
Oa2--16 to 34 inches; black (5YR 2/1) broken face and rubbed sapric material; about 35 percent fiber, less than 10 percent rubbed; weak coarse platy structure; friable; primarily herbaceous fibers; slightly alkaline; gradual smooth boundary.
Oe1--34 to 50 inches; dark reddish brown (5YR 2/2) broken face and rubbed hemic material; about 90 percent fiber, about 40 percent rubbed; weak coarse platy structure; nonsticky, nonplastic; primarily herbaceous fibers; slightly alkaline; abrupt smooth boundary.
Oa3--50 to 60 inches; dark reddish brown (5YR 2/2) broken face, black (5YR 2/1) rubbed sapric material; about 20 percent fiber, less than 5 percent rubbed; weak coarse subangular blocky structure; nonsticky, nonplastic; primarily herbaeous fibers; slightly alkaline.
TYPE LOCATION: Huron County, Michigan; about 2 miles south of Verona; 238 feet west and 2,450 feet north of the southeast corner, sec. 25, T. 16 N., R. 13 E.
RANGE IN CHARACTERISTICS: The organic layers are more than 51 inches thick. Hue of the organic portion of the profile is 5YR to 10YR, or it is neutral, and value and chroma are 0 to 3. Some pedons contain up to 15 percent by volume of woody fragments that cannot be crushed between the fingers. Reaction ranges from moderately acid to slightly alkaline. The difference between mean winter and mean summer temperature is more than 30 degrees F. The surface tier consists of sapric or hemic material or both. Structure is typically granular, but in some pedons it is blocky.
Some pedons have an Op horizon.
The subsurface tier is dominantly sapric material, but at least 10 inches of this tier and/or the bottom tier is hemic material. It typically has platy structure but is sometimes blocky or massive in the subsurface and bottom tiers.
Some pedons have a limnic layer below 51 inches.
Some pedons have a mineral C below 51 inches.
COMPETING SERIES: This is the Seattle series. Seattle soils occur in a mild marine climate having cool dry summers and mild wet winters. Seattle soils have a difference between mean winter and mean summer soil temperature of 15 to 30 degrees F
GEOGRAPHIC SETTING: Pinnebog soils are on bogs with a plane or concave surface. Slope gradients are less than 2 percent. The soils formed in dominantly herbaceous organic deposits. The Pinnebog soils occur in a continental climate having warm moist summers and cold winters. The mean annual temperature ranges from 47 to 52 degrees F, and the mean annual precipitation ranges from 29 to 37 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Guelph, Linwood, Palms, Parkhill, and Wasepi soils. Guelph, Parkhill, and Wasepi soils formed from mineral rather than organic materials. They are on the uplands surrounding Pinnebog soils. Linwood and Palms soils are on bogs but have loamy mineral substratums at depths of 16 to 51 inches.
DRAINAGE AND PERMEABILITY: Very poorly drained. Potential surface runoff is negligible or very low. Permeability is moderately slow to moderately rapid.
USE AND VEGETATION: Most of the Pinnebog soils are in forest of red and silver maple, green and black ash, quaking aspen, white birch, white cedar, tamarack and tag alder. Areas which have been cleared are used for pasture, and if drained, for corn, wheat, potatoes, and truck crops.
DISTRIBUTION AND EXTENT: Southern Michigan. MLRA 97, 98, 99, 111, and 144A. The series is not extensive, with a total of approximately 5,000 acres mapped.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana
