Strata of finer textures occur in some pedons. Reaction ranges from slightly acid to moderately alkaline. This is the Fishtrap series. Fishtrap soils have a difference of less than 16 degrees F between mean summer and mean winter soil temperatures and are more acid than slightly acid in the mineral underlying materials. Adrian soils formed in herbaceous organic material and in the underlying sandy deposits and occupy shallow closed depressions primarily on outwash plains, lake plains, lake terraces and flood plains, but can occur within moraines and till plains.
Areas range from a few acres to several hundred acres in size.
Slope gradients range from 0 to 1 percent. Usually adjacent upland soils are sandy. The mean annual temperature is about 48 to 53 degrees F., mean annual precipitation ranges from 29 to 45 inches, frost free days range from 120 to 180 days, and elevation ranges from 580 feet to 1530 feet above sea level. These are the Antung, Edselton, Houghton and Granby soils. The very poorly drained Antung, Edselton, and Houghton soils are on similar landscape positions as Adrian soils.
