Reaction ranges from strongly acid to neutral. The C or Cg horizon has hue of 5YR to 5Y or is neutral, value of 2 to 6, and chroma of 0 to 4. It is sand, coarse sand, fine sand, loamy sand, or loamy sand and their gravelly or very gravelly analogues. Rock fragment content ranges from 0 to 60 percent. 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.
