Abstract

The aims of this paper were to determine how soil properties that affect erodibility vary between slope position and drainage class for a hydrosequence of soils developed in loess deposits of the lower Mississippi River Valley. Soil samples were collected from the A- and B-horizons of the 5 representative pedons in the Memphis catena whose drainage class varied from well-drained to poorly-drained. Soil erodibility was assessed by the use of an aggregation index computed from water dispersible clay relative to total clay contents. The results suggest that cementing agents responsible for soil aggregate stabilization are mobilized under conditions of relatively low redox potentials which increase soil erodibility
