The Desker series consists of very deep, somewhat excessively drained soils formed in gravelly loamy and gravelly sandy outwash. These soils are moderately deep over sand and gravel.
Permeability is moderately rapid in the solum and very rapid in the underlying material.
These soils are on kames, eskers, terraces, and outwash plains. Slopes range from 6 to 18 percent. Desker sandy loam on a 10 percent slope in a cultivated field. The depth to free lime and the base of the argillic horizon is 20 to 40 inches. Rock fragments average 12 to 25 percent throughout the control section, some subhorizons have from 5 to 35 percent.
