Nachusa soils do not have rock fragments in the lower part of the series control section. Nenno soils are less than 102 cm (40 inches) to the base of the argillic horizon.

GEOGRAPHIC SETTING: The Tiderishi soils are on lake plains of late Wisconsinan age. Slope ranges from 0 to 2 percent. Tiderishi soils formed in stratified loamy and silty glaciolacustrine material 102 to 152 cm (40 to 60 inches) thick overlying till. Mean annual precipitation ranges from 686 to 914 mm (27 to 36 inches). Mean annual air temperature ranges from 7 to 11 degrees C (45 to 52 degrees F). Frost-free period is 140 to 165 days. Elevation is 183 to 244 meters (600 to 800 feet) above mean sea level.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the moderately well drained Jenera and somewhat poorly drained Vanlue soils on slight rises, low knolls, and ridges; and the very poorly drained Rensselaer soils on flats and in depressions and drainageways.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Somewhat poorly drained. The depth to the top of an intermittent perched high water table ranges from 15 to 46 cm (0.5 to 1.5 feet) between November and April in normal years. The potential for surface runoff is negligible to low. Saturated hydraulic conductivity is moderately high in the solum and moderately low in the substratum. Permeability is moderate in the solum and moderately slow or slow in the substratum.

USE AND VEGETATION: A large proportion is under cultivation, primarily corn, soybeans, wheat, and hay. A few areas are used for specialty crops such as tomatoes and sugar beets. A relatively small proportion is in woodland. Native vegetation is deciduous forest, principally ash, beech, elm, and maple.

DISTRIBUTION AND EXTENT: Northwestern Ohio, and possibly northeastern Indiana and southern Michigan; MLRAs 99 and 111B. The type location is in MLRA 99. The series is of small extent.
