The first kind is a layer having a pH of less than 3.5. The second\none is a layer having an electrical conductivity of more than 12. The third kind is a possible dense layer determined through an examination of the differential \nbetween the populated bulk density of a layer and a theoretical optimum density.

Miscellaneous areas (non-soil\nmaterials) did not contribute to the map unit weighted average so the weighted mean represents only the\nsoils in each map unit.
