The Atterberg consistency constants afford a simple means of determining the relative dLfferences in the consistency of various soils. They are being used by many soil survey workers not only as a measure of variations in the consistency of different soils, but also as an expression of the differences occurring in the horizons of any specific soil profile. Since the value of these constants is in part, if not entirely, dependent upon the amount and nature of the colloidal material present, it is evident that they should furnish some index to the physical characteristics of soils. Although values for the Atterberg constants have been obtained for a large number of soils, a satisfactory interpretation of their significance does not exist. It is the purpose of this paper to discuss the different factors that affect the Atterberg consistency constants and to present a new interpretation of their relationship to the dynamic properties of soils involved in tillage and implement design. The Atterberg constants used in this study were (a) the upper plastic l~mit, (b) the lower plastic limit, and (c) the plasticity number.
