RENSSELAER SERIES


The Rensselaer series consists of very deep, poorly drained or very poorly drained soils formed in loamy sediments on till plains, stream terraces, outwash terraces, outwash plains, glacial drainage channels, and lake plains.

GEOGRAPHIC SETTING: Rensselaer soils are in depressions on till plains, stream terraces, outwash terraces, outwash plains, glacial drainage channels, and lake plains. Slope ranges from 0 to 2 percent. Rensselaer soils formed in loamy sediments. Mean annual precipitation ranges from 864 to 1118 mm (34 to 44 inches). Mean annual temperature ranges from 10.0 to 13.9 degrees C (50 to 57 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 Brookston, Crosier, Martinsville, and Whitaker soils. The poorly drained Brookston soils are in depressions similar to the Rensselaer soils. The somewhat poorly drained Crosier and Whitaker soils and the well drained Martinsville soils are on swells and knolls on till plains, stream terraces, outwash terraces, or outwash plains.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained or very poorly drained. In undrained areas, depth to the top of an apparent seasonal high water table ranges from 61 cm (2 feet) above the surface to 15 cm (0.5 foot) below during the winter and spring in normal years. In drained areas, depth to the top of an apparent seasonal high water table ranges from 15 cm (0.5 foot) above the surface to 30 cm (1 foot) below the surface during the winter and spring in normal years. Potential for surface runoff is negligible. Saturated hydraulic conductivity is moderately high. Permeability is moderate.

USE AND VEGETATION: Soils are used to grow corn, soybeans, and small grain. Native vegetation is swamp grasses and deciduous hardwood forest.

DISTRIBUTION AND EXTENT: MLRAs 97, 98, 99, 110, 111A, 111B, 111C, 111D, 114B, and 115A in Indiana, Illinois, Michigan, and Ohio. The series is of large extent.

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Indianapolis, Indiana.

SERIES ESTABLISHED: Newton County, Indiana, 1948.

REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon: from the surface to a depth of 38 cm (15 inches) (Ap and A horizons).
Argillic horizon: from a depth of 38 to 107 cm (15 to 42 inches) (Btg1, Btg2, and Btg3).
Aquic conditions: redoximorphic features present in all horizons below a depth of 28 cm (11 inches).

Till substratum, sandy substratum, loamy substratum, and clay loam substratum phases, and a mucky surface phase are recognized, and may become new series when subset soil surveys with these phases are updated. In addition, an undrained phase is recognized.

NASIS Data Mapunit ID 155043 represents the typical pedon.
NASIS Data Mapunit ID 401579 represents the mucky loam surface phase.

ADDITIONAL DATA: Transect data (T98IN-099-001) for the typical pedon is on file in MLRA project office, Plymouth, Indiana. Transect shows 80 percent Rensselaer soils and 20 percent Brookston soils.
