In addition, Martinton and Mundelein soils have mollic epipedons and Wauconda soils have darker colored surface horizons. Zurich soils are on similar landscapes. Jericho soils have darker colored surface horizons. Montgomery and Pella soils are in depressional areas, are poorly drained, and have mollic epipedons. The potential for surface runoff is, typically medium or high, but ranges from low to very high.
Permeability is moderately slow.
Most areas are in cropland. Principal crops are corn, oats, and forages. Small areas, mostly on the more sloping relief, are in pasture or woodland. Native vegetation is mixed hardwoods. Saylesville soils are of moderate extent.
