The calcium carbonate equivalent of the till is 40 to 60 percent. Mean annual temperature ranges from approximately 45 to 48 degrees F, and mean annual precipitation ranges from 28 to 34 inches. These are the Hochheim , Lamartine , and Mayville soils that are on similar landscapes. The well drained Hochheim soils commonly occupy steeper slopes and have sola less than 24 inches thick. The moderately well drained Mayville and somewhat poorly drained Lamartine soils commonly occupy gentler slopes or level sites in nearby areas where the loess mantle is more than 22 inches thick.
Surface runoff is medium or rapid.
Permeability is moderate in the solum and slow in the substratum. Native vegetation was maple-basswood. Theresa soils are extensive. Dodge County, Wisconsin, 1974. This soil was at one time included with the Miami series.
