OGEMAW SERIES
The Ogemaw series consists of very deep, somewhat poorly drained soils formed in sandy outwash and in the underlying till or lacustrine deposits on ground moraines, lake plains, and outwash plains. Slope ranges from 0 to 6 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: Sandy over loamy, mixed, semiactive, frigid, ortstein Typic Durorthods
TYPICAL PEDON: Ogemaw loamy sand, on a concave, 2 percent slope in a cultivated area. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 18 cm (7 inches); very dark grayish brown (10YR 3/2) loamy sand, dark grayish brown (10YR 4/2) dry; weak medium granular structure; very friable; moderately acid; abrupt smooth boundary. [13 to 23 cm (5 to 9 inches) thick]
E--18 to 25 cm (7 to 10 inches); pinkish gray (7.5YR 6/2) loamy sand, pinkish gray (7.5YR 7/2) dry; weak fine subangular blocky structure; very friable; moderately acid; clear irregular boundary. [5 to 15 cm (2 to 6 inches) thick]
Bsm--25 to 51 cm (10 to 20 inches); dark reddish brown (5YR 3/4) loamy sand, 5 to 13 cm (2 to 5 inches) thick, that grades to yellowish red (5YR 5/6) loamy sand; weak medium subangular blocky structure; very firm; cemented; moderately acid; clear wavy boundary. [20 to 38 cm (8 to 15 inches) thick]
Bs--51 to 66 cm (20 to 26 inches); brown (10YR 4/3) loamy sand; weak coarse subangular blocky structure; friable; in places tongues of cemented material extend downward from the horizon above; many fine faint brown (10YR 5/3) and pale brown (10YR 6/3) masses of oxidized iron throughout; moderately acid; abrupt wavy boundary. [10 to 25 cm (4 to 10 inches) thick]
2C1--66 to 102 cm (26 to 40 inches); reddish brown (5YR 4/4) sandy clay loam; strong medium angular blocky fragments; plastic when wet; many fine prominent dark grayish brown (2.5Y 4/2) iron depletions throughout; slightly effervescent; slightly alkaline; clear wavy boundary. [0 to (30 inches) thick]
2C2--102 to 152 cm (40 to 60 inches); yellowish brown (10YR 5/6) and gray (2.5Y 5/1) silty clay; strong medium angular blocky fragments; plastic when wet; slightly effervescent; moderately alkaline.

COMPETING SERIES: There are no other series in the same family.
GEOGRAPHIC SETTING: Ogemaw soils are on ground moraines, lake plains, and outwash plains. Slope ranges from 0 to 6 percent. These soils formed in sandy outwash 51 to 102 cm (20 to 40 inches) thick and in the underlying till or lacustrine deposits. Mean annual precipitation ranges from 686 to 838 mm (27 to 33 inches). Mean annual temperature ranges from 5.0 to 8.3 degrees C (41 to 47 degrees F).
GEOGRAPHICALLY ASSOCIATED SOILS: Ogemaw soils are associated with the well drained
Menominee and
Manistee soils and the somewhat poorly drained
Iosco and
Allendale soils. All of these lack the strongly cemented B horizons.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. Depth to the top of a perched seasonal high water table ranges from 15 to 46 cm (0.5 to 1.5 feet) between October and May in normal years. Potential for surface runoff is very low to medium. Saturated hydraulic conductivity is high or very high above the Bsm horizon, moderately high or high in the Bsm horizon, and moderately high or moderately low in the C horizon. Permeability is rapid in the A, E and Bs horizons, moderate or moderately rapid in the Bsm horizon and slow or moderately slow in the C horizon.
USE AND VEGETATION: Only a small portion of this soil has been cleared. It is used for pasture and woodland. Woodlands consist of mixed Northern hardwoods and pines, eastern hemlock, and white cedar.
DISTRIBUTION AND EXTENT: MLRAs 94A, 94C, 96, and 98 in northern Michigan. This series is of small extent.

SERIES ESTABLISHED: Antrim County, Michigan, 1923.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 25 cm (10 inches) (A and E horizons).
Albic horizon: from a depth of 18 to 25 cm (7 to 10 inches) (E horizon).
Spodic horizon: from a depth of 25 to 66 cm (10 to 26 inches) (Bsm and Bs horizons).
This series will be investigated when the type location is updated. A new Oxyaquic subgroup may be proposed if needed.
