The Buchel series consists of very deep, moderately well drained, very slowly permeable soils developed in clayey, calcareous alluvial sediments. These soils are on nearly level flood plains. Slopes range from 0 to 1 percent. Solum thickness is more than 80 inches.
Texture is clay or silty clay throughout.
Weighted average clay content of the particle-size control section is 40 to 60 percent. Reaction is slightly or moderately alkaline throughout. Amplitude of waviness between the A and Bss horizons is 5 to 14 inches. Undisturbed areas have gilgai microrelief with microknolls 2 to 8 inches above the microdepressions. Depth to slickensides and wedge shaped peds begin at a depth ranging from 8 to 24 inches and range from few to common.
