These soils are on very gently sloping to moderately steep sloping uplands with gradients ranging from 1 to 15 percent. The Leisy soils formed in eolian sand and the underlying loess. The mean annual temperature ranges from 49 to 51 degrees F, and mean annual precipitation ranges from 24 to 28 inches. The Moody and Thurman soils are the principal associated soils on the landscape. Moody soils are on similar landscapes.
Thurman soils are sandy and are higher on the landscape.
Surface runoff ranges from low on the very gently sloping areas to moderately high on the moderately steep sloping areas. Permeability is moderate in the upper part and moderately slow in the lower part. The very gently to strongly sloping areas are commonly cropped to corn, alfalfa, and soybeans. The steeper slopes are most commonly in native grass. The series is of moderate extent.
