An energy-based index of dry soil stability is related closely to abrasion susceptibility of soils during wind erosion, as well as other soil physical processes. Unfortunately, the currently used soil-aggregate crushing-energy meter (SACEM) requires aggregates to have a uniquely defined break force in order to measure dry stability. Users have found many conditions of interest where this break force is absent. Thus, the objective of this study was to design a vertical soil crushing-energy meter (VSCEM) that did not require an initial break force, used commercially available components, and obtained measurements faster than the SACEM.
