About two-thirds of the species range is dominated by Ultisols, which are low in bases and have subsurface horizons of clay accumulation. The strength characteristics of Hickory are influenced considerably by the spacing of its growth rings. Tree volume tables are available (2,19). A single trunk canker near the base is a sign that the butt log is badly infected, and multiple cankers are evidence that the entire tree may be a cull. Washington, DC.
