BANLIC SERIES

The Banlic series consists of very deep, somewhat poorly drained soils formed in acid, silty alluvium on flood-plain steps and low stream terraces. Slope ranges from 0 to 3 percent. Mean annual precipitation is about 1016 mm (40 inches), and mean annual temperature is about 12.8 degrees C (55 degrees F).

TAXONOMIC CLASS: Coarse-silty, mixed, active, acid, mesic Fragic Epiaquepts

COMPETING SERIES: There are other series in this family.

GEOGRAPHIC SETTING: Banlic soils are on flood-plain steps and low stream terraces. Slope gradients typically are between 0 and 2 percent and range from 0 to 3 percent. These soils formed in acid, silty alluvium. Mean annual temperature ranges from 12.2 to 13.9 degrees C (54 to 57 degrees F). Mean annual precipitation ranges from 914 to 1118 mm (36 to 44 inches). Frost-free period is 180 to 210 days. Elevation is 103.7 to 152.4 meters (340 to 500 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Belknap, Bonnie, Haymond, Racoon, Sharon, Wakeland, and Wilbur soils. None of these soils have horizons with fragic soil properties. All of these soils except Racoon are on lower lying landform positions and formed in more recent alluvium. Racoon soils are on similar or slightly higher landform positions and have an argillic horizon and a thicker albic horizon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. In drained areas, depth to the top of an intermittent perched high water table ranges from 15 to 61 cm (0.5 foot to 2.0 feet) between November and May in normal years. Some areas are subject to rare to frequent flooding for brief periods between January and May. Potential for surface water runoff is low. Saturated hydraulic conductivity is moderately high (1.41 to 4.23 micrometers/second) in the surface layer and substratum, and moderately low or moderately high (0.42 to 1.41 micrometers/second) in the subsoil. Permeability is moderately slow in the surface layer and substratum, and slow in the subsoil.

USE AND VEGETATION: Most areas are cropped to corn, soybeans, and small grain. Some areas are pastured or wooded. Native vegetation is deciduous forest common to flood-plain areas.

DISTRIBUTION AND EXTENT: MLRA 113 and LRUs 114B, 115A, and 115B in southern Illinois and southern Indiana. This series is of moderate extent.

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

SERIES ESTABLISHED: Saline County, Illinois, 1975.

REMARKS: The upper part of the control section for family reaction class (E horizon) has been affected by liming and is higher than defined for the acid class. The Banlic soils will be evaluated throughout their MLRA extents to determine the proper classification.

Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to a depth of 33 cm (13 inches) (Ap and E horizons).
Albic horizon: from a depth of 23 to 33 cm (9 to 13 inches) (E horizon).
Cambic horizon: from a depth of 33 to 127 cm (13 to 50 inches), (Bg1, Bg2, Bxg1 and Bxg2 horizons).
Fragic soil properties: from a depth of 76 to 127 cm (30 to 50 inches), (Bxg1 and Bxg2 horizons).
