Mean annual temperature ranges from 49 to 55 degrees F., and mean annual precipitation ranges from 29 to 40 inches. The frost free period is 150 to 198 days, and elevation ranges from 570 to 1,020 feet above mean sea level. The moderately well drained Brems, somewhat poorly drained Morocco, and well drained Osolo soils are on slightly lower swells. The very poorly drained Maumee and Newton soils are in depressions. The potential for surface runoff is negligible to low.
Permeability is rapid.
Depth to the top of an intermittent apparent seasonal high water table is greater than 6.0 feet. Mostly used to grow corn, soybeans, fall seeded small grain and legume-grass mixtures. Irrigation is a common practice on cropped areas. Some areas are in woods or pasture. Native vegetation is deciduous forest.
