LOCATION REMUS MIEstablished Series
TAXONOMIC CLASS: Fine-loamy, mixed, semiactive, mesic Haplic Glossudalfs
TYPICAL PEDON: Remus sandy loam - on a 5 percent southwest-facing convex slope in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 6 inches; dark brown (10YR 3/3) sandy loam, light brownish gray (10YR 6/2) dry; moderate medium granular structure; friable; many very fine roots; about 4 percent gravel and 1 percent cobbles; neutral; abrupt smooth boundary. (6 to 10 inches thick)
E--6 to 9 inches; light yellowish brown (10YR 6/4) sandy loam; moderate medium granular structure; friable; common very fine roots; about 5 percent gravel and cobbles; slightly acid; abrupt wavy boundary. (0 to 14 inches thick)
E/B--9 to 18 inches; pale brown (10YR 6/3) sandy loam (E); moderate very fine subangular blocky structure; common very fine pores; very hard when dry, friable when moist; occupies about 70 percent of the horizon as tongues extending into or completely surrounding isolated remnants of brown (7.5YR 5/4) sandy clay loam (Bt); moderate fine subangular blocky structure; firm; common faint brown (7.5YR 4/4) clay films on vertical faces of peds; few fine roots; about 5 percent gravel; neutral; clear wavy boundary. (0 to 16 inches thick.)
B/E--18 to 23 inches; brown (7.5YR 5/4) sandy clay loam (Bt); weak fine subangular blocky structure; firm; few faint brown (7.5YR 4/4) clay films on surfaces of some peds; occupies about 85 percent of the horizon completely surrounded or penetrated by tongues of pale brown (10YR 6/3) sandy loam (E); few fine roots; about 5 percent gravel; neutral; clear wavy boundary. (0 to 19 inches thick)
Bt--23 to 32 inches; brown (7.5YR 5/4) sandy clay loam; weak medium subangular blocky structure; firm; few very fine roots; many distinct dark yellowish brown (10YR 4/4) clay films on faces of peds; about 2 percent gravel; neutral; gradual wavy boundary. (6 to 31 inches thick)
BC--32 to 60 inches; brown (7.5YR 5/4) sandy clay loam; weak fine subangular blocky structure; firm; about 2 percent gravel; neutral. (0 to 32 inches thick)
TYPE LOCATION: Mecosta County, Michigan; about 6 miles south and 1 mile east of Remus; 1,716 feet north and 150 feet east of the southwest corner of sec. 23, T. 13 N., R. 7 W.
RANGE IN CHARACTERISTICS: The thickness of the solum and the depth to free carbonates ranges from 40 to greater than 60 inches. Gravel and cobble content ranges from 1 to 15 percent throughout. The solum ranges from strongly acid to neutral.
The Ap horizon has hue of 10YR, value of 2 to 4, and chroma of 2 or 3. Uncultivated areas have an A horizon, 2 to 6 inches thick. It has hue of 10YR, value of 2 to 4, and chroma of 1 to 3. The E horizon has hue of 10YR, value of 5 to 7, and chroma of 2 to 4. The A and E horizons are sandy loam, fine sandy loam, or loamy sand.
The E part of the E/B and B/E horizons has hue of 7.5YR or 10YR, value of 5 or 6 anc chroma of 3 or 4. Textures are similar to these of the overlying E horizon. The E part of the E/B and B/E horizons is brittle when dry. Roots do not penetrate the matrix of the brittle material. The amount of E material in the E/B or B/E horizon ranges from 15 to as much as 75 percent. The B part of the E/B and B/E horizons has colors and textures similar to those of the underlying Bt horizon.
Some pedons have a Bw horizon.
The Bt horizon has hue of 5YR to 10YR, value of 3 to 5, and chroma of 4 or 6. It is sandy clay loam, loam, or sandy loam. The argillic horizon ranges in clay from 10 to 30 percent, but averages 18 to 25 percent. The BC horizon has hue of 7.5YR or 10YR, value of 5, and chroma of 4 or 6. It is sandy clay loam or sandy loam.
Some pedons have a C horizon within a depth of 60 inches. Where present it has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 or 4. It is loam, sandy loam or sandy clay loam; however, pockets of sand or loamy sand are in some pedons. It is slightly alkaline or moderately alkaline.
COMPETING SERIES: This is the Filer series. Filer soils have carbonates above a depth of 40 inches.
GEOGRAPHIC SETTING: The Remus soils are on ground and end moraines of Wisconsinan age. They formed in loamy glacial till. Slopes typically are 0 to 18 percent, but range from 0 to 60 percent. Mean annual precipitation ranges from 30 to 32 inches, and mean annual temperature ranges from 45 to 49 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Locke, Marlette, Owosso, and Spinks soils. Locke soils are somewhat poorly drained and are in a drainage sequence with Remus soils. Spinks soils are coarser textured. Marlette soils are finer textured. Owosso soils have a finer textured substratum than Remus soils. Marlette, Owosso, and Spinks soils are on similar topographic positions as Remus soils.
DRAINAGE AND PERMEABILITY: Well drained. Potential surface runoff is negligible to very high depending on the slope. Permeability is moderately slow.
USE AND VEGETATION: A large portion of the gentle slopes are cultivated. Corn, alfalfa, and small grain are the principal crops. Other areas are in woodland.
DISTRIBUTION AND EXTENT: The central portion of lower Michigan. The series is of moderate extent.

SERIES ESTABLISHED: Mecosta County, Michigan, 1982.
REMARKS: Diagnostic horizons and other features recognized in this pedon are: ochric epipedon - the zone from the surface to 9 inches (Ap and E horizons); argillic horizon - the zone from 18 to 32 inches (B part of B/E and Bt horizon); glossic horizon - the zone from 9 to 23 inches (E/B and B/E horizons); tongues of albic material that extend into the argillic horizon less than 20 inches - haplic feature.
The classification of the soil was changed from fine-loamy, mixed, mesic Glossorboric Hapludalfs to fine-loamy, mixed, mesic Haplic Glossudalfs with this draft.
