The Bon series consists of very deep, well drained and moderately well drained soils formed in alluvium on bottom lands of the glacial till plain.
Permeability is moderate.
Slopes range from 0 to 2 percent. Bon loam - on plane slope of 1 percent in native grass. When described the soil was moist to a depth of 38 inches. Typically the depth to carbonates ranges from 6 to 20 inches, but some pedons contain carbonates throughout. Thickness of the mollic epipedon ranges from 20 to 50 inches or more.
