MAUMEE SERIES

The Maumee series consists of very deep, poorly drained or very poorly drained soils formed in sandy outwash or sandy sediments in depressions on outwash plains and lake plains. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 889 mm (35 inches), and mean annual temperature is about 10.0 degrees C (50 degrees F).

TAXONOMIC CLASS: Sandy, mixed, mesic Typic Endoaquolls

TYPICAL PEDON: Maumee loamy sand, on a less than 1 percent slope in a cultivated field at an elevation of 200 meters (657 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

Ap--0 to 25 cm (10 inches); black (10YR 2/1) loamy sand, dark gray (10YR 4/1) dry; weak medium granular structure; very friable; few fine and medium roots; neutral; abrupt smooth boundary.

A--25 to 58 cm (10 to 23 inches); very dark gray (10YR 3/1) loamy sand, gray (10YR 5/1) dry; weak coarse subangular blocky structure; very friable; few fine roots; few fine prominent dark yellowish brown (10YR 3/6) masses of oxidized iron in the matrix; common coarse faint dark grayish brown (10YR 4/2) iron depletions in the matrix; neutral; clear wavy boundary. [Combined thickness of the A horizon is 38 to 61 cm (15 to 24 inches).]

Bg1--58 to 81 cm (23 to 32 inches); grayish brown (10YR 5/2) sand; single grain; loose; few fine roots; few fine very dark gray (10YR 3/1) organic matter accumulations in the matrix; few fine prominent dark yellowish brown (10YR 4/6) masses of oxidized iron in the matrix; common coarse faint dark gray (10YR 4/1) iron depletions in the matrix; neutral; clear wavy boundary.

Bg2--81 to 96 cm (32 to 38 inches); grayish brown (10YR 5/2) sand; single grain; loose; few fine roots; common medium distinct yellowish brown (10YR 5/4) and few medium prominent dark yellowish brown (10YR 4/6) masses of oxidized iron in the matrix; neutral; abrupt wavy boundary. [Combined thickness of the Bg horizon is 25 to 76 cm (10 to 30 inches).]

Cg1--96 to 155 cm (38 to 61 inches); light brownish gray (10YR 6/2) fine sand; single grain; loose; common medium prominent brownish yellow (10YR 6/6) masses of oxidized iron in the matrix; neutral; abrupt wavy boundary.

Cg2--155 to 203 cm (61 to 80 inches); grayish brown (10YR 5/2) coarse sand and sand; single grain; loose; slightly alkaline.

COMPETING SERIES: These are the Granby, Gumz, Kentland, and Loup series. Granby soils have a mollic epipedon that is less than 38 cm (15 inches) in thickness. Gumz soils have less than 85 percent sand in the lower part of the series control section. Kentland soils have an organic layer in the middle part of the series control section. Loup soils have a buried A horizon in the lower part of the series control section.

GEOGRAPHIC SETTING: Maumee soils are in depressions on outwash plains and lake plains. Slope ranges from 0 to 2 percent. Maumee soils formed in sandy outwash or sandy sediments. Mean annual precipitation ranges from 762 to 1041 mm (30 to 41 inches). Mean annual temperature ranges from 7.8 to 12.2 degrees C (46 to 54 degrees F). Frost-free period is 130 to 180 days. Elevation is 177 to 466 meters (580 to 1,530 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Granby soils and the Adrian, Brems, Chelsea, Coloma, Denham, Gilford, Houghton, Morocco, Newton, Oakville, Plainfield, and Watseka soils. The Granby and Gilford soils and the very poorly drained Newton soils are on similar landforms nearby. The Gilford soils are coarse-loamy and the Newton soils have an umbric horizon. The very poorly drained Adrian and Houghton soils formed in organic material and are in deeper depressions. The moderately well drained Brems and Denham soils are on swells. The excessively drained Chelsea, Oakville, and Plainfield soils and the somewhat excessively drained Coloma soils are on higher lying swells and dunes. The somewhat poorly drained Morocco and Watseka soils are on swells on outwash plains.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained or very poorly drained. Depth to the top of an apparent seasonal high water ranges from 61 cm (2 feet) above the surface to 30 cm (1 foot) below the surface for some time in normal years. Potential for surface runoff is negligible. Saturated hydraulic conductivity is high or very high. Permeability is rapid.

USE AND VEGETATION: Soils are mostly used to grow corn, soybeans, and wheat. Many areas that are drained are irrigated. Native vegetation is marsh grasses, reeds, sedges, and water-tolerant trees.

DISTRIBUTION AND EXTENT: MLRAs 94A, 95B, 97, 98, 110, 111B, and 111C in northern Indiana, southern Michigan, southern Wisconsin, and northeastern Illinois. The series is of large extent.

SERIES ESTABLISHED: Porter County, Indiana, 1916.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon: from the surface to to a depth of 58 cm (23 inches) (Ap, A horizons)
Aquic conditions: redoximorphic features in the lower part of the mollic epipedon and in all horizons below a depth of 25 cm (10 inches).

A loamy surface phase has been recognized and will likely become a new series as subsets with this phase are updated.

NASIS Data Mapunit ID 124282 represents the typical pedon.
NASIS Data Mapunit ID 154992 represents the loamy fine sand surface phase for northern Indiana.
NASIS Data Mapunit ID 154993 represents the mucky loamy fine sand surface phase for northern Indiana.

ADDITIONAL DATA: Lab characterization data is available for the typical pedon (PR7612) from Purdue University Soil Characterization Lab, AES Bulletin No. 222, Volume 4, Pg. 116. Transect data (T99IN-127-001) for the typical pedon is on file in the MLRA project office, Plymouth, Indiana. Transect shows 100 percent Maumee soils.
