The Lisbon series consists of very deep, somewhat poorly drained soils on till plains. These soils formed in loess or other silty material and in the underlying loamy till.
Permeability is moderate in the solum and moderately slow in the underlying material.
Slope ranges from 0 to 4 percent. 42 degrees 9 minutes 23 seconds N., and long. 88 degrees 43 minutes and 27 seconds W., NAD 27. The depth to the base of soil development ranges from 24 to 42 inches. The depth to carbonates and the depth to horizons with greater that 15 percent sand ranges from 20 and 40 inches.
