The Brodale soils overlie or formed in fragmented limestone bedrock. The Bellechester soils formed primarily in sandstone bedrock. The Frontenac soils formed in a loamy mantle over loamy-skeletal colluvium. The well drained Lindstrom soils formed in silty materials and are downslope from the Eyota soils. The well drained Port Byron soils occur on upper or lower slopes of less gradient.
Surface runoff is medium and rapid.
Permeability is moderate. Soils with slopes of less than 12 percent primarily are cropped to corn and soybeans, but some are pastured. Soils with slopes over 12 percent primarily are pastured. Olmsted County, Minnesota, 1978. Refer to Minn. Agr.
