These soils form a toposequence with Mermill soils. The somewhat poorly drained Aurand and Haskins soils are on slightly higher landscape positions. The moderately well drained Houcktown and the well drained Rawson soils are on higher or more sloping landscape positions. Very poorly drained. A perched water table is 1 foot above the surface to 1 foot below the surface from December to May in most years.
Permeability is moderate in the loamy material and slow or very slow in the underlying till.
The potential for surface runoff is negligible or very low. Nearly all of the Mermill soils have been drained and are used for cropland. Principal crops are corn, soybeans, oats, wheat, alfalfa, tomatoes, and sugar beets. Native vegetation is deciduous swamp forest with swamp white oak, bur oak, pin oak, elm, hickory, and ash. The Mermill soils occur in MLRA 99 in northwestern Ohio and northeastern Indiana and to a lesser extent in MLRA 111 in west-central Ohio and northern Indiana.
