EDMORE SERIES

The Edmore series consists of very deep, poorly drained or very poorly drained soils formed in stratified sandy and loamy material on till plains and moraines. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 762 mm (30 inches), and mean annual temperature is about 8.9 degrees C (48 degrees F).

TAXONOMIC CLASS: Sandy, mixed, mesic Mollic Endoaquents

TYPICAL PEDON: Edmore sandy loam, on a level area in a cultivated field. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 23 cm (9 inches); very dark grayish brown (10YR 3/2) sandy loam; weak medium granular structure; friable; slightly acid; abrupt smooth boundary. [15 to 23 cm (6 to 9 inches) thick]

Bg1--23 to 30 cm (9 to 12 inches); light brownish gray (10YR 6/2) loamy sand; weak medium granular structure; very friable; common medium distinct dark yellowish brown (10YR 4/4) and prominent brownish yellow (10YR 6/8) masses of oxidized iron; moderately acid; clear wavy boundary. [10 to 25 cm (4 to 10 inches) thick]

Bg2--30 to 71 cm (12 to 28 inches); grayish brown (10YR 5/2) loamy sand; weak medium subangular blocky structure; very friable; common medium prominent yellowish brown (10YR 5/6) masses of oxidized iron; moderately acid; gradual wavy boundary. [10 to 64 cm (4 to 25 inches) thick]

Bg3--71 to 81 cm (28 to 32 inches); grayish brown (2.5Y 5/2) sandy loam; weak medium subangular blocky structure; friable; many fine prominent yellowish brown (10YR 5/8) and brownish yellow (10YR 6/8) masses of oxidized iron; slightly acid; abrupt irregular boundary. [0 to 46 cm (18 inches) thick]

Cg--81 to 152 cm (32 to 60 inches); light brownish gray (2.5Y 6/2) loamy sand; massive; very friable; many medium prominent yellowish brown (10YR 5/8) masses of oxidized iron; slightly effervescent; moderately alkaline.

TYPE LOCATION: Ionia County, Michigan; 2,280 feet north and 600 feet west of the southeast corner of sec. 4, T. 7 N., R 8 W.

Mean annual soil temperature: 8.3 to 11.1 degrees C (47 to 52 degrees F)

Ap horizon:
Hue: 10YR
Value: 2 or 3
Chroma: 1 or 2
Texture: sandy loam or loamy sand
Reaction: slightly acid or neutral

A horizon, where present:
Thickness: 10 to 18 cm (4 to 7 inches)

Bg horizon:
Hue: 10YR or 2.5Y
Value: 5 to 7
Chroma: 1 or 2
Texture: commonly loamy sand or less commonly sandy loam in the upper part; sandy loam to loamy sand with strata of sandy or fine sand in the lower part
Structure: weak or moderate, fine to coarse, granular or subangular blocky
Reaction: moderately acid to neutral in the upper part and slightly acid to slightly alkaline in the lower part

Cg horizon:
Hue: 10YR or 2.5Y
Value: 5 to 7
Chroma: 1 or 2
Texture: predominantly loamy sand with strata of sand, fine sand and sandy loam occurring in layers up to 15 cm (6 inches) in thickness

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

GEOGRAPHIC SETTING: Edmore soils are on level to depressional areas on moraines and till plains of Wisconsinan age. Slope ranges from 0 to 2 percent. The climate is continental. Mean annual precipitation ranges from 711 to 787 mm (28 to 31 inches). Mean annual temperature ranges from 7.2 to 10.6 degrees C (45 to 51 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These include the well drained Spinks soils and the somewhat poorly drained Thetford soils. The somewhat poorly drained Pipestone soils and the very poorly drained Kingsville and Granby soils are also common sandy associates. The somewhat finer textured Barry soils occur near Edmore in some areas.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained or very poorly drained. Potential for surface runoff is negligible to low. Saturated hydraulic conductivity is moderately high or high. Permeability is moderate or moderately rapid.

USE AND VEGETATION: Largely wooded areas with elm, ash and red maple the dominant species. Some areas are cleared and used for pasture. A few areas are drained and used for production of small grain and corn.

DISTRIBUTION AND EXTENT: MLRAs 96 and 98 in central part of the lower peninsula of Michigan. The series is of moderate extent.
