MAXINKUCKEE SERIES

The Maxinkuckee series consists of very deep, very poorly drained soils formed in herbaceous organic material over limnic material (coprogenous earth) over loamy till or lacustrine sediments in depressions on till plains and moraines. Slope ranges from 0 to 1 percent. Mean annual precipitation is about 940 mm (37 inches), and mean annual temperature is about 10.0 degrees C (50 degrees F).

TAXONOMIC CLASS: Coprogenous, euic, mesic Limnic Haplosaprists

TYPICAL PEDON: Maxinkuckee muck, on a slope of less than 1 percent in a cultivated field at an elevation of about 246 meters (807 feet) above mean sea level. (Colors are for moist soil unless otherwise stated.)

Oap--0 to 15 cm (0 to 6 inches); black (N 2.5/) rubbed and broken face muck (sapric material); 5 percent unrubbed fiber, 0 percent rubbed; weak fine granular structure; very friable; slightly acid; abrupt smooth boundary.

Oa1--15 to 41 cm (6 to 16 inches); black (N 2.5/) rubbed and broken face muck (sapric material); 5 percent unrubbed fiber, 0 percent rubbed; moderate medium subangular blocky structure; friable; slightly acid; clear wavy boundary.

Oa2--41 to 61 cm (16 to 24 inches); black (N 2.5/) rubbed and 80 percent dark brown (7.5YR 3/2) and 20 percent very dark gray (10YR 3/1) broken face muck (sapric material); 8 percent unrubbed fiber, 0 percent rubbed; moderate medium subangular blocky structure; friable; common fine prominent dark brown (7.5YR 3/4) masses of oxidized iron in the matrix; moderately acid; abrupt smooth boundary. [Combined thickness of the Oap and Oa horizons is 41 to 114 cm (16 to 45 inches).]

Lco1--61 to 84 cm (24 to 33 inches); olive gray (5Y 4/2) coprogenous silty clay loam; weak coarse prismatic structure; firm; neutral; clear wavy boundary.

Lco2--84 to 107 cm (33 to 42 inches); dark gray (5Y 4/1) coprogenous silty clay loam; massive; friable; strongly effervescent; slightly alkaline; clear wavy boundary. [Combined thickness of the Lco horizon is 61 to 107 cm (24 to 42 inches).]

Cg--107 to 203 cm (42 to 80 inches); gray (10YR 5/1) silt loam; massive; friable; strongly effervescent; slightly alkaline.

TYPE LOCATION: Marshall County, Indiana; about 3 miles southeast of the town of Bremen; 1060 feet west and 1900 feet south of the northeast corner of sec. 18, T. 34 N, R. 4 E; USGS Nappanee West topographic quadrangle; lat. 41 degrees 23 minutes 58.1 seconds N. and long. 86 degrees 6 minutes 4.5 seconds W., NAD 27; UTM Zone 16, 575129 easting and 4583499 northing, NAD 83.

RANGE IN CHARACTERISTICS:
Thickness of the herbaceous organic layers: 41 to 114 cm (16 to 45 inches)
Depth to coprogenous earth: 41 to 114 cm (16 to 45 inches)
Organic fibers: derived primarily from herbaceous plants
Depth to the underlying mineral soil material: 64 to 130 cm (25 to 51 inches)

Oap or Oa horizon:
Hue: 7.5YR, 10YR, or is neutral
Value: 2, 2.5, or 3
Chroma: 0 to 3
Texture: muck (sapric material)
Reaction: moderately acid to neutral

Lco horizon:
Hue: 10YR to 5Y
Value: 2 to 4
Chroma: 1 to 6
Texture: coprogenous silt loam or coprogenous silty clay loam
Shell fragments: 0 to 20 percent
Reaction: neutral or slightly alkaline

Cg horizon:
Hue: 10YR or 2.5Y
Value: 3 to 6
Chroma: 1 or 2
Texture: silt loam, silty clay loam, loam, or clay loam
Sand content: 2 to 45 percent
Reaction: neutral or slightly alkaline

COMPETING SERIES: These are the Moston, Muskego, Toto, and Wawayanda series. Moston soils have more than 45 percent sand in the lower part of the control section. Muskego soils do not have mineral material within 130 cm (51 inches) of the surface. Toto soils have marly material (Lma) within the control section. Wawayanda soils do not occur on till plains and moraines and are in areas that receive more than 991 mm (39 inches) of annual precipitation.

GEOGRAPHIC SETTING: Maxinkuckee soils are in depressions on till plains and moraines. Slope gradients range from 0 to 1 percent. They formed in herbaceous organic material over limnic material (coprogenous earth) over loamy till or lacustrine sediments. Mean annual precipitation ranges from 889 to 991 mm (35 to 39 inches). Mean annual temperature ranges from 8.9 to 10.6 degrees C (48 to 51 degrees F). Frost-free period is 140 to 170 days. Elevation is 195 to 285 meters (640 to 935 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brookston, Muskego, Palms, Rensselaer, and Thomas soils. The Brookston and Rensselaer soils are loamy throughout and generally are at the outer margins of the depressions. The Muskego soils are not underlain by loamy sediments. The Palms and Thomas soils lack coprogenous earth.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Very poorly drained. Potential for surface runoff is negligible. Saturated hydraulic conductivity is moderately high or high in the herbaceous organic material, moderately low in the coprogenous earth, and moderately high or high in the underlying loamy sediments.

USE AND VEGETATION: Soils are used mostly to grow cultivated crops. Corn and soybeans are the principal crops, but some vegetable truck crops are also grown. Native vegetation is water-tolerant trees, grasses, sedges, reeds, and shrubs.

DISTRIBUTION AND EXTENT: MLRA 111C in northern Indiana. The series is of small extent, about 200 acres.
