LOCATION DEERHEART MIEstablished Series
TAXONOMIC CLASS: Fine-loamy, mixed, semiactive, nonacid, frigid Aeric Endoaquepts
TYPICAL PEDON: Deerheart silt loam - on a 1 percent slope in an idle field on a lake plain at an elevation of about 1152 feet. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 6 inches; very dark grayish brown (10YR 3/2) silt loam; light brownish gray (10YR 6/2) dry; many fine prominent strong brown (7.5YR 4/6) mottles; moderate fine and medium subangular blocky structure; friable; many fine and common medium roots; about 1 percent fine gravel; slightly acid; abrupt smooth boundary. (0 to 10 inches thick)
Bg--6 to 27 inches; gray (10YR 5/1) silty clay loam; moderate medium and coarse subangular blocky structure; firm; many fine prominent yellowish brown (10YR 5/8) iron accumulations and common fine prominent gray (5Y 5/1) iron depletions throughout; common fine and few medium roots; few distinct dark grayish brown (10YR 4/2) clay coatings in root channels; about 1 percent fine gravel; neutral; clear wavy boundary. (8 to 24 inches thick)
BC--27 to 43 inches; light olive brown (2.5Y 5/4) silty clay loam with thin strata of silt and silt loam; moderate medium and coarse subangular blocky structure; firm; many medium prominent yellowish brown (10YR 5/8) iron accumulations throughout and common coarse prominent light brownish gray (10YR 6/2) and greenish gray (5GY 5/1) iron depletions on faces of peds and along fracture planes; about 10 percent light gray (10YR 7/1) calcium carbonate accumulations along faces of peds; about 1 percent fine gravel; strongly effervescent; moderately alkaline; clear wavy boundary. (10 to 20 inches thick)
C--43 to 80 inches; brown (10YR 5/3) silty clay loam stratified with light olive brown (2.5Y 5/4) very fine sandy loam, silt, and silt loam; massive; firm; many coarse distinct yellowish brown (10YR 5/6) iron accumulations and common medium faint light brownish gray (10YR 6/2) iron depletions throughout; about 1 percent fine and medium gravel; strongly effervescent; moderately alkaline.
TYPE LOCATION: Crawford County, Michigan; about 12 miles southeast of the city of Grayling, 750 feet north and 800 feet east of the southwest corner of sec. 15, T. 25 N., R. 2 W.
RANGE IN CHARACTERISTICS: The thickness of the solum ranges from 20 to 48 inches. Depth to free carbonates ranges from 20 to 35 inches. Gravel content ranges from 0 to 5 percent throughout the profile. The particle-size control section averages 27 to 35 percent clay.
The Ap horizon has hue of 10YR, value of 2 or 3, and chroma of 1 or 2. It is loam, silt loam, or silty clay loam. Undisturbed areas have a thin O horizon overlying an A horizon. Reaction is slightly acid or neutral.
The Bg horizon has hue of 10YR to 5G, value of 4 to 6, and chroma of 1 or 2. It is silty clay loam or clay loam. Reaction ranges from slightly acid to slightly alkaline.
The BC horizon has hue of 10YR or 2.5Y, value of 4 to 6, and chroma of 2 to 4. It is dominantly silty clay loam or clay loam with thin strata of clay, silt, silt loam, or very fine sandy loam. Reaction is slightly alkaline or moderately alkaline.
The C horizon has hue of 7.5YR to 2.5Y, value of 5 or 6, and chroma of 1 to 4. It is dominantly silty clay loam or clay loam with strata of loamy very fine sand, very fine sandy loam, silt, silt loam, and clay. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Angelica, Aurelie, Easton and Gulf series and the closely related Bruce, Hettinger, Kilmanagh, and Springport series. Angelica soils are not stratified within depths of 20 to 60 inches. Aurelie soils have high bulk density substratums associated with the dense till. Easton and Gulf soils do not contain free carbonates within 60 inches. In addition Easton soils contain from 5 to 35 percent rock fragments throughout and Gulf soils contain from 5 to 35 percent rock fragments within 20 to 40 inches. Bruce and Hettinger soils have chromas of 2 or less in the upper part of the control section. Springport soils are in the fine family. Kilmanagh soils have mean annual soil temperatures of more than 47 degrees F.
GEOGRAPHIC SETTING: Deerheart soils are on glacial lake plains and depressions on outwash plains. Slopes range from 0 to 2 percent. Mean annual precipitation ranges from 28 to 32 inches and mean annual temperature ranges from 40 to 45 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Allendale, Bowers, Croswell, Nunica, Perecheney, and Wakeley soils. The somewhat poorly drained Bowers and the moderately well drained Nunica soils are in the same drainage sequence. The poorly drained Wakeley and somewhat poorly drained Allendale soils have sandier upper sola and are on similar or slightly higher landscape positions. The moderately well drained Croswell and Perecheney soils are on higher landscape positions.
DRAINAGE AND PERMEABILITY: Poorly drained and very poorly drained. The soil has a seasonal apparent high water table that ranges from 1 foot above to 1 foot below the surface from September to June. Surface runoff is very slow or ponded. Permeability is slow.
USE AND VEGETATION: Most areas of this soil are idle cropland or hayland. Uncultivated areas have common tree species which include quaking aspen, speckled alder, willow, balsam fir, and northern white cedar.
DISTRIBUTION AND EXTENT: Northern Lower Michigan and the Upper Peninsula of Michigan. The series is of small extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana
SERIES ESTABLISHED: Crawford County, Michigan, 1992.
REMARKS: Diagnostic horizons and features recognized in this pedon are: ochric epipedon - the zone from the surface to 6 inches (Ap horizon); cambic horizon - the zone from 6 to 43 inches (Bg and BC horizons); matrix colors with chroma of 3 or more within 30 inches of the surface - aeric feature; aquic soil moisture regime.
