Vlasaty soils formed in 12 to 24 inches of loess or loamy sediment and underlying firm glacial till. Mean annual temperature ranges from 45 to 47 degrees F, and mean annual precipitation ranges from 28 to 33 inches. These are Renova , Sargeant , and Skyberg series which formed in materials similar to the Vlasaty series and are members of a hydrosequence with this series. The Renova soils are well drained and the Sargeant and Skyberg soils are somewhat poorly drained. Moderately well drained.
Surface runoff is medium.
Permeability is moderately slow. Commonly cropped to corn and soybeans. Some of it is in forest or in pasture. Native vegetation was deciduous forest and Savanna with oaks being the dominant tree. Dodge County, Minnesota, 1959.
