Frost-free period ranges from 130 to 186 days. These are the Bremer and Wiota soils. The poorly drained Bremer soils are on the more level lower-lying parts of the low stream benches. The moderately well drained and well drained Wiota soils are on slight rises or short side slopes. Somewhat poorly drained - seasonal high saturation occurs within depths of 1.0 to 2.0 feet during April to June in normal years and is considered apparent.
Surface runoff is low.
Permeability is moderate. Soils are cultivated. Corn, hay, small grains, and soybeans are principal crops. Native vegetation is tall prairie grasses. Adams County, Iowa, 1960.
