In areas where Ashdale soils are on ridgetops, Dodgeville soils are on the steeper side slopes. Where Ashdale soils are on side slopes, Tama soils commonly are on ridgetops. Most of the lesser sloping areas are cropped to corn, hay, legume-grass, pasture, or small grains. Steeper slopes are mainly used for pasture. Native vegetation was probably tall prairie grasses, chiefly bluestem.
Extent is moderate.
