The Boyer series consists of very deep, well drained soils formed in sandy and loamy glacial drift underlain by sand or gravelly sand outwash at depths of 20 to 40 inches. The soils are on outwash plains, valley train, kames, beach ridges, river terraces, lake terraces, deltas and moraines.
Permeability is moderately rapid in the loamy horizons and very rapid in the sandy horizons.
Slopes range from 0 to 50 percent. Boyer loamy sand - on a 4 percent slope in a cultivated field. The thickness of the solum ranges and depth to the sand and gravel substratum ranges from 20 to 40 inches and corresponds to the depth to carbonates. The solum ranges from moderately acid to moderately alkaline. Rock fragments, dominantly gravel, range from 1 to 30 percent in the solum and from 2 to 55 percent in the 3C horizon.
