Permeability is moderate in the loamy sediments, moderately slow in the 2B horizons, and slow or very slow in the underlying dense till. An intermittent perched high water table is at a depth of 2.0 to 3.5 feet between January and April in normal years. Nearly all areas are cultivated. Corn, soybeans, wheat, oats, and hay are the principal crops. Some areas are used for tomatoes and sugar beets, and a few areas are used for pasture or remain in woods.
Native vegetation is mixed hardwood forest.
The series is of moderate extent. Allen County, Ohio, 1963. Future updates of the soil surveys in Indiana and Ohio may require it to be moved again. This revision also incorporates the concept of the Royerton Series into the range of the Rawson soils, thus the Royerton Series will become inactive upon acceptance of the revised Rawson concept. Detailed analysis of the clay contents of the till members in which these soils have been formed indicates two series cannot be consistently separated.
