Zadog soils formed in sandy outwash. Granby and Maumee soils are on similar topographic positions and do not have iron accumulations in the solum. Morocco soils are on slightly convex rises, do not have iron accumulations in the solum, and are somewhat poorly drained. Very poorly drained. Runoff is very slow or ponded.
Permeability is moderate or moderately rapid in the solum and rapid in the underlying material.
Most areas of Zadog soils are drained and cropped to corn and soybeans. Small grain and specialty crops are also grown. A few areas are used for hay and pasture. Native vegetation was elm, silver maple, and river birch. Zadog series is of moderate extent.
