DEERHEART SERIES

The Deerheart series consists of very deep, poorly drained or very poorly drained soils that formed in silty and loamy glaciolacustrine deposits on glacial lake plains and depressions on outwash plains. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 762 mm (30 inches), and mean annual temperature is about 6.1 degrees C (43 degrees F).

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 351 meters (1152 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 15 cm (6 inches); very dark grayish brown (10YR 3/2) silt loam, light brownish gray (10YR 6/2) dry; moderate fine and medium subangular blocky structure; friable; many fine and common medium roots; many fine prominent strong brown (7.5YR 4/6) masses of oxidized iron; about 1 percent fine gravel; slightly acid; abrupt smooth boundary. [0 to 25 cm (10 inches) thick]

Bg--15 to 69 cm (6 to 27 inches); gray (10YR 5/1) silty clay loam; moderate medium and coarse subangular blocky structure; firm; common fine and few medium roots; few distinct dark grayish brown (10YR 4/2) clay coatings in root channels; many fine prominent yellowish brown (10YR 5/8) masses of oxidized iron; common fine faint gray (5Y 5/1) iron depletions throughout; about 1 percent fine gravel; neutral; clear wavy boundary. [20 to 61 cm (8 to 24 inches) thick]

BC--69 to 109 cm (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) masses of oxidized iron throughout; common coarse distinct light brownish gray (10YR 6/2) and prominent 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. [25 to 51 cm (10 to 20 inches) thick]

C--109 to 203 cm (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) masses of oxidized iron throughout; 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:

Value: 4 to 6
Chroma: 2 to 4
Texture: dominantly silty clay loam or clay loam with thin strata of clay, silt, silt loam, or very fine sandy loam

C horizon:
Hue: 7.5YR to 2.5Y
Value: 5 or 6

Texture: dominantly silty clay loam or clay loam with strata of loamy very fine sand, very fine sandy loam, silt, silt loam, and clay
Reaction: slightly alkaline or moderately alkaline

COMPETING SERIES: These are no other series in the same family.

GEOGRAPHIC SETTING: Deerheart soils are on glacial lake plains and depressions on outwash plains. Slope ranges from 0 to 2 percent. These soils formed in silty and loamy glaciolacustrine deposits. Mean annual precipitation ranges from 711 to 813 mm (28 to 32 inches). Mean annual temperature ranges from 4.4 to 7.2 degrees C (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 or well drained Nunica soils are in the same drainage sequence. The poorly drained or very poorly drained Wakeley and the 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 SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained or very poorly drained. The depth to the top of an apparent seasonal high water table ranges from 30 cm (1 foot) above to 30 cm (1 foot) below the surface between September and June in normal years. The potential for surface runoff is negligible. Saturated hydraulic conductivity is moderately low. 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: MLRA 94A in northern Lower Michigan. This series is of small extent.
