Osco and Newvienna soils average less clay in the particle-size control section, are moderately well drained, and are on similar and more sloping landform positions. Rubio and Virden soils are poorly drained, and on slightly lower to depressional landform positions. In addition, Rubio soils have a thinner dark surface soil, and Virden soils do not have an E horizon. Somewhat poorly drained. Surface runoff is slow.
Permeability is moderately slow.
The seasonal high water table is at a depth of 1.0 to 2.0 feet below the surface in the spring. These soils are mostly cultivated. Corn and soybeans are the dominant crops. Small acreages are used for small grains and meadow. Brown County, Illinois, 1997.
