EC ranges from 0 to 2 mmhos throughout. Reaction is neutral or slightly alkaline. Texture of the Bt is clay loam or loam with 20 to 35 percent clay and more than 15 percent but less than 35 percent fine sand or coarser. Reaction is slightly or moderately alkaline. Texture is loam or clay loam with 20 to 35 percent clay.
Reaction is moderately or strongly alkaline.
Calcium carbonate ranges from 5 to 10 percent. Texture is loam or clay loam with 20 to 30 percent total clay of which about 2 to 4 percent is carbonate clay. Reaction is typically moderately alkaline but may be strongly alkaline when sodic shales are present. Calcium carbonate equivalent is 5 to 15 percent, but some horizons may exceed 15 percent but are discontinuous or too thin to be considered as a calcic. The Cr is weakly consolidated sedimentary rock.
