Monroe topographic quadrangle; lat. 41 degrees 58 minutes 28.07 seconds N. and long. 83 degrees 24 minutes 17.43 seconds W., NAD 27; UTM Zone 17, 300756 easting and 4649742 northing, NAD 83.
RANGE IN CHARACTERISTICS: The depth to base of the argillic horizon ranges from 24 to 50 inches. The thickness of the sandy material ranges from 20 to 40 inches. Rock fragment content ranges from 0 to 5 percent in the A, E, and Bw horizons, and from 0 to 10 percent in the 2B and 2C horizons.
The Ap or A horizon has hue of 10YR, value of 2 to 4, and chroma of 1 to 3. It is sand, fine sand, loamy sand, or loamy fine sand. Reaction ranges from strongly acid to neutral.
The E horizon has hue of 7.5YR or 10YR, value of 5 or 6, and chroma of 2 to 4. It is sand, fine sand, loamy sand, or loamy fine sand. Reaction ranges from strongly acid to neutral.
The Bw horizon has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 3 to 8. It is sand, fine sand, loamy sand, or loamy fine sand. Reaction ranges from strongly acid to neutral.
The 2Bt1 or 2Btg1 horizon has hue of 7.5YR or 10YR, value of 4 to 6, and chroma of 1 to 6. It is sandy loam, sandy clay loam, loam, or silt loam. Clay content is less than 35 percent. Reaction ranges from strongly acid to slightly alkaline.
The 2Bt2 or 2Btg2 horizon has hue of 5YR to 2.5Y, value of 4 to 6, and chroma of 1 to 4. It is clay loam, silty clay loam, or loam. Clay content is less than 35 percent. Reaction ranges from strongly acid to slightly alkaline.
The 2Cg or 2C horizon has hue of 5YR to 10YR, value of 5 or 6, and chroma of 1 to 6. It is clay loam, loam, silt loam, or silty clay loam. Clay content is less than 35 percent. Reaction is slightly alkaline or moderately alkaline.
COMPETING SERIES: These are the Bixler, Branch, Leola, Markton, Rimer, and Riverdale series. Bixler soils have an E horizon that is more than 15 inches thick. Branch soils have more than 10 percent rock fragments throughout the argillic horizon. Leola soils are more acid than slightly alkaline in the lower part of the series control section. Markton soils average less than 20 percent clay in the lower part of the argillic horizon. Rimer soils have 2B horizons that average more than 35 percent clay. Riverdale soils have more than 10 percent rock fragments in the lower part of the series control section.
GEOGRAPHIC SETTING: Selfridge soils formed in 20 to 40 inches of sandy material and the underlying loamy till on moraines, lake plains, and low sand dunes of Wisconsinan Age. Slope gradients range from 0 to 6 percent. Mean annual temperature ranges from 47 to 52 degrees F., mean annual precipitation ranges from 28 to 36 inches, frost-free period ranges from 130 to 180 days, and elevation ranges from 580 to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Blount, Brookston, Conover, Crosier, Del Rey, Fulton, Lenawee, Oakville, Pewamo, Spinks, and Toledo soils. The somewhat poorly drained Blount, Conover, Crosier, Del Rey, and Fulton soils are on similar landform positions and do not have sandy materials in the upper part of the series control section. The poorly drained Brookston and Lenawee soils and the very poorly drained Pewamo and Toledo soils are in depressions. The excessively drained Oakville soils and the well drained Spinks are on higher rises and dunes and have sandy materials throughout the series control section.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is very low or negligible. Permeability is rapid in the sandy material and moderately slow or slow in the underlying loamy till. The depth to the top of a seasonal high water table ranges from 1 to 2 feet for some time in normal years.
USE AND VEGETATION: This soil is used for cropland and pasture. Vegetables, corn, small grains, and legume-grass hay are the principal crops. Native vegetation is mixed hardwoods, with beech, American elm, northern red oak, and maple the principal species.
DISTRIBUTION AND EXTENT: MLRA's 97, 98 99, and 111 in southern Michigan and northern Indiana. The series is of large extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Macomb County, Michigan, 1970.
REMARKS: Diagnostic horizons and features recognized in this pedon are: ochric epipedon - from the surface to 25 inches (Ap, E, and Bw horizons); argillic horizon - from 25 to 32 inches (2Bt1 and 2Bt2 horizons). Udic moisture regime.
ADDITIONAL DATA: Lab characterization data is available from the National Soil Survey Laboratory, Lincoln, NE. Transect data (T99-MI-115-002) for the typical pedon is on file in MLRA project office, Plymouth, Indiana. Transect shows 90 percent Selfridge soils and 10 percent Pewamo soils.
