The mean annual air temperature ranges from 53 to 57 degrees F, and the mean annual precipitation ranges from 40 to 44 inches. These are the Taftown and the Hosmer soils. Taftown soils do not have fragipans and are downslope on steeper slopes. Hosmer soils formed in more than 48 inches of loess and are on similar landscape positions. Moderately well drained, surface runoff is medium or rapid.
Permeability is moderate above the fragipan and slow in the fragipan.
Soils are mostly cropped to corn and soybeans. Winter wheat is the principal small grain. Native vegetation was hardwood trees. Gibson County, Indiana, 1986.
