Mean annual temperature ranges from 45 to 53 degrees F, and mean annual precipitation ranges from 27 to 35 inches. These are the Conover , Dodge , Kendall , and Mayville soils. The well drained Dodge and the moderately well drained Mayville are common associates on the somewhat steeper gradients. Kendall soils are on nearby areas of similar slopes where loess thickens beyond 36 inches, and Conover soils are on nearby areas of similar slopes where loess thins out to less than 20 inches. Somewhat poorly drained.
Surface runoff is slow or medium.
Permeability is moderate. Most of the soil is cultivated to corn, small grain, and forage crops. The Lamartine soils are of moderate extent. Green County, Wisconsin, 1969. The differentiae between the Herbert series and Lamartine series is not strong if the typical pedons are compared.
