High potential includes Subclasses Ve through VIIIe. Moderate potential includes Subclasses IIIe a

other subclasses. 

B Includes areas where rock may be found within 60 inches below ground surface. C Parameters of classification of soils with poor revegetation potential include those that are highly acidic, soils with slopes greater than 8 percent, and soils 

coarse fragments (rocks and stones) in the surface layer of soil. 

D Soils with clay loam or finer textures and somewhat poor to very poor drainage characteristics are considered to have severe compaction potential.
