The Toddville series consists of very deep, moderately well drained soils which are deep to sandy alluvium. These soils formed mostly in silty alluvium underlain by stratified sandy alluvium. They typically are on stream terraces but some are on outwash plains.
Permeability is moderate in the silty and loamy mantle and rapid in the sandy alluvium.
Slopes range from 0 to 6 percent. Mean annual precipitation is about 30 inches. Toddville silt loam - on a 2 percent slope in a cultivated field at an elevation of about 760 feet. Thickness of the silty alluvium, depth to the base of the argillic horizon, and depth to sandy alluvium all range from 40 to 60 inches. Thickness of the mollic epipedon ranges from 10 to 20 inches.
