The Gudgel series consists of deep, moderately well drained soils formed in loess and the underlying residuum from shale and sandstone.
Permeability is moderate in the upper part of the solum and slow in the fragipan.
Slopes range from 6 to 18 percent. Mean annual temperature is 55 degrees F, and mean annual precipitation is 44 inches. Gudgel silt loam - on a 15 percent slope in an idle field. The solum is 40 to 60 inches thick and corresponds to the depth to bedrock. Depth to the fragipan ranges from 10 to 14 inches.
