COMPETING SERIES: This is the Edwards series. Edwards soils do not have sand in the lower part of the series control section.
GEOGRAPHIC SETTING: Edselton soils formed in herbaceous organic material overlying marly material and sand deposits and are in shallow closed depressions primarily on outwash plains, lake plains, lake terraces, and flood plains, but can occur within moraines and till plains. Slope gradients range from 0 to 1 percent. Mean annual temperature ranges from 48 to 53 degrees F., mean annual precipitation ranges from 30 to 42 inches, frost-free period ranges from 130 to 180 days, and elevation ranges from 580 feet to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Adrian, Antung, Houghton, Madaus, Martisco, Moston, Toto, and the competing Edwards soils. These very poorly drained soils are on similar landform positions as Edselton soils. Adrian and Antung soils formed in herbaceous organic material over sandy material. Edwards soils do not have sand within 51 inches. Houghton soils formed in herbaceous organic material more than 51 inches thick. Madaus and Martisco soils formed in less than 16 inches of herbaceous organic material over marly material. Moston and Toto soils formed in herbaceous organic material over coprogenous earth.
DRAINAGE AND PERMEABILITY: Very poorly drained. The potential for surface runoff is negligible. Permeability is moderately slow to moderately rapid in the organic material, slow in the marly material, and rapid in the underlying sand. The depth to the top of an apparent seasonal high water table ranges from 1 foot above the surface to 1 foot below the surface for some time in normal years.
USE AND VEGETATION: Drained soils are cropped mostly with corn and soybeans. Undrained soils are in native vegetation consisting of marsh grasses, sedges, cattails, and water tolerant trees.
DISTRIBUTION AND EXTENT: MLRA 111 and 98 in northern Indiana and southern Michigan. The soils are of small extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Pulaski County, Indiana, 2001.
REMARKS: Drained and undrained phases are recognized. Diagnostic horizons and features recognized in this pedon are:
Histic epipedon: muck from the surface to 16 inches (Oap, Oa)
Aquic conditions: from the surface to 80 inches
Limnic subgroup: marly material from 21 to 48 inches (Lma)
NASIS Data Mapunit ID 152937 represents the typical pedon.
NASIS Data Mapunit ID 152938 represents the undrained phase.
ADDITIONAL DATA: Lab characterization data is available for the typical pedon (S99IN-131-002) from the National Soil Survey Laboratory, Lincoln, NE. Transect data (T99IN-131-014) is on file in MLRA project office, Plymouth, Indiana. Transect shows 60 percent Edselton soils, 20 percent Edwards soils, and 20 percent Houghton soils
