BATAVIA SERIES


The Batavia series consists of very deep, well drained soils on till plains, glacial outwash plains, and stream terraces. These formed in loess or other silty material and in loamy stratified outwash or sandy loam till. Slope ranges from 0 to 12 percent. The mean annual precipitation is about 890 mm (35 inches), and the mean annual temperature is about 8.3 degrees C (47 degrees F).

COMPETING SERIES: These are the Bowes, Churchtown, Deroin, Downs, Ella, Festina, Frankville, Gladek, Greenbush, Harvard, Hersey, Knox, Luana, Mannon, Massbach, Mellott, Mt. Carroll, Myrtle, Nasset, Newhouse, Shelbyville, Watkins, Waubeek, and Yutan soils. Bowes soils have more than 5 percent coarse materials and more than 90 percent sand in the lower 1/4 of the control section. Churchtown, Downs, Greenbush, Knox, Mannon, Mt. Carroll, and Yutan soils contain less than 10 percent sand in the lower 1/4 of the control section and formed in loess. Deroin soils have hue redder than 10YR in the Bt horizon. Ella, Festina, and Watkins soils contain less sand in the lower part of the sola and formed in alluvial materials. Frankville soils have a lithic contact within a depth of 102 cm (40 inches). Gladek soils formed in lacustrine sediments. Harvard, Mellott, and Waubeek soils have more than 10 percent sand within a depth of 102 cm (40 inches). Hersey and Myrtle soils contain less silt in the lower part of the B and C horizon. Luana soils have thinner sola. Massbach, Nasset, and Shelbyville soils average more than 35 percent clay in the lower part of the B horizon and have the lower part of the B horizon formed in residuum from limestone or shale. Newhouse soils contain strata and more sand above a depth of 102 cm (40 inches) and formed in a thinner mantle of loess.

GEOGRAPHIC SETTING: Batavia soils are on loess covered sandy loam till plains, glacial outwash plains, or stream terraces. Slope gradients range from 0 to 12 percent. These soils formed in 102 to 152 cm (40 to 60 inches) of loess or other silty material and in loamy stratified outwash or in sandy loam till. Summers are hot and winters are cold. The mean annual temperature ranges from 6.7 to 12.2 degrees C (44 to 54 degrees F), mean annual precipitation ranges from 890 to 1143 mm (35 to 45 inches), and frost free period ranges from 140 to 180 days.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Harvard, Plano, St. Charles, Virgil, and Drummer soils. Harvard, Plano, and St. Charles soils are on nearby similar landscapes. Virgil soils are generally less sloping and are somewhat poorly drained. Drummer soils are poorly drained soils on nearly level parts and in depressions of till plains and outwash plains and have a mollic epipedon.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. Surface runoff is low on the gentle slopes and medium on the steeper slopes. Saturated hydraulic conductivity is moderately high to high (4.23 to 14.11 micrometers per second) in the solum and moderately high to very high (4.23 to 42.34 micrometers per second) in the substratum. Permeability is moderate in the solum and moderate or moderately rapid in the substratum.

USE AND VEGETATION: Most areas of these soils are cultivated. Corn, soybeans, small grains, and legume hay are the major crops. Native vegetation is a mixture of prairie grasses and trees.

DISTRIBUTION AND EXTENT: Central and northern Illinois, and southern Wisconsin. LRR's K and M, MLRAs 95B, 105, 108A, 108B, 110, and 115C. The series is of moderate extent.
