The Hanover series consists of deep, moderately well drained and well drained soils formed in weathered Illinoian glacial till with a thin mantle of loess in some areas. These soils are on uplands and have slopes ranging from 0 to 40 percent.
Permeability is moderate above the fragipan and slow in the fragipan.
Hanover silt loam - on a 3 percent convex ridgetop in a cultivated field. Thickness of the solum typically is more than 60 inches but ranges from 50 to 110 inches. Depth to the fragipan is 16 to 35 inches. Some pedons have a mantle of loess up to 16 inches thick and have 2B and 2C horizons. Rock fragments, mostly gravel-sized subrounded fragments of sandstone and shale, are 2 to 25 percent, by volume, in the solum below any loess mantle and 5 to 35 percent in the C horizon.
