The Wasepi series consists of somewhat poorly drained soils formed in loamy deposits underlain by sand and gravel at 20 to 40 inches.
Permeability is moderately rapid in the solum and rapid in the underlying sand and gravel.
Slopes range from 0 to 6 percent. Wasepi sandy loam - on a 1 percent slope in a cultivated area. The thickness of the solum and the depth to free carbonates ranges from 20 to 40 inches. The solum ranges from medium acid to mildly alkaline. Rock fragments, dominantly gravel, range from 3 to 25 percent in the solum and from 15 to 50 percent in the 2C horizon.
