SELFRIDGE SERIES

The Selfridge series consists of very deep, somewhat poorly drained soils formed in sandy material and the underlying loamy till on moraines, relict nearshore zones, wave-worked till plains, till-floored lake plains, glacial deltas, and low sand dunes. Slope ranges from 0 to 6 percent. Mean annual precipitation is about 815 mm and the mean annual temperature is about 9 degrees C.

TAXONOMIC CLASS: Loamy, mixed, active, mesic Aquic Arenic Hapludalfs

COMPETING SERIES: These are the Bixler, Leola, Markton, and Rimer series. Bixler soils have lacustrine materials in the lower part of the series control section. Leola soils have more than 85 percent sand in the lower part of the series control section. Markton soils average 20 percent or less clay in the lower part of the argillic horizon. Rimer soils have densic materials within the series control section.

GEOGRAPHIC SETTING: Selfridge soils are on moraines, relict nearshore zones, wave-worked till plains, till-floored lake plains, glacial deltas, and low sand dunes of Wisconsinan age. Slope ranges from 0 to 6 percent. Selfridge soils formed in 51 to 100 cm of sandy material and the underlying loamy till. Mean annual precipitation ranges from 710 to 960 mm. Mean annual temperature ranges from 7 to 11 degrees C. Frost-free period is 130 to 210 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Belleville, Blount, Brems, Brookston, Capac, Conover, Crosier, Oakville, Parkhill, Pewamo, Spinks, and Tedrow soils. The somewhat poorly drained Blount, Capac, Conover, and Crosier soils are on similar landform positions and do not have sandy materials in the upper part of the series control section. The somewhat poorly drained Tedrow soils are on similar landform positions and have sandy materials throughout the series control section. The poorly drained Brookston, the poorly and very poorly drained Belleville and Parkhill, and the very poorly drained Pewamo soils are in depressions. The excessively drained Oakville, the well drained Spinks, and the moderately well drained Brems soils are on higher rises and dunes and have sandy materials throughout the series control section.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. The depth to the top of a seasonal high water table ranges from 30 to 60 cm for some time in normal years. The potential for surface runoff is very low or negligible. Saturated hydraulic conductivity is high or very high in the sandy material and moderately high or moderately low in the underlying loamy till.

USE AND VEGETATION: Most areas of this soil are cultivated or in 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 as the principal species.

DISTRIBUTION AND EXTENT: MLRA's 97, 98, 99, 111B, and 111C in southern Michigan and northern Indiana. These soils are extensive, with about 385,000 acres of the series mapped.

SOIL SURVEY REGIONAL OFFICE (SSRO) RESPONSIBLE: AMHERST, MASSACHUSETTS

SERIES ESTABLISHED: Macomb County, Michigan, 1970.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 38 cm (Ap and E horizons).
Argillic horizon: from a depth of 64 to 81 cm (2Bt horizon).
Lithologic discontinuity: from a depth of 64 to 200 cm (2Bt and 2Cg horizons).
Aquic conditions: redox depletions present in all horizons below the Ap horizon.

A dense substratum phase is currently recognized in MLRA 99. Future evaluation is needed to verify the presence of densic material in other MLRAs where this series occurs.

A stony surface phase is currently recognized in MLRA 99. Future evaluation is needed to place these soils into a more appropriate series concept.

ADDITIONAL DATA: Lab characterization data is available from the National Soil Survey Laboratory, Lincoln, NE.
