Slopes range from 0 to 7 percent. These soils formed in materials that have washed from associated soils on adjacent landscapes and in the underlying residuum. The mean annual temperature ranges from 59 to 68 degrees F, and the mean annual precipitation ranges from 40 to 46 inches. These are the Appling , Cecil , Colfax , Durham , Granville , Louisburg , Madison , Mayodan , and Worsham soils. Appling, Cecil, Madison, and Mayodan soils are in a clayey family.
Colfax soils have a fragipan.
Durham and Granville soils do not have low chroma mottles in the upper 24 inches of their Bt horizons. Louisburg soils do not have continuous Bt horizons and have coarser texture. Worsham soils are poorly drained. Most areas of this soil are cleared and used for growing corn, wheat, soybeans, truck crops, and pasture. The natural vegetation was forest of oaks, pine, and gum.
