Rheometry ever since made part of soil physical characterization, but only since the availability of highly sensitive rheometers, amplitude sweep tests (AST) and thixotropy tests are conducted on structured and homogenized soil, mostly one the base of few or one rheological parameter. Comprehensive and simultaneous analysis of different parameters has not been done yet, though it offers valuable clues to the highly complex soil processes and their multidimensional (spatial, temporal, and stress-rate-dependent) interferences, especially with regard to the role of the most important soil aggregation factors, i.e., soil organic matter (SOM) and water content. Consequently, we conducted a strain-controlled AST under varying normal stresses sigma(n)on different soil aggregate fractions of either high or low SOM content and at different water contents. We determined shear stress tau, loss and storage modulusG '' andG ', respectively, and their ratio, tan delta, at the end of the linear viscoelastic range (LVR) and the yield point (YP) as well as the strain at which they occurred. In addition, we analyzed tan delta curves for dilatancy, and classified shear failure behavior (plastic or brittle). Viscoelasticity parameters were mostly affected by SOM (i.e., electrostatical attractive forces) and strain (spatial impact), while shear stress parameters altered with SOM,sigma(n), and water content (friction and particle coordination). Based on integrated interpretation of the AST and its resulting parameters, we developed a conceptual framework to be used in future soil (micro)mechanical characterization, where rheological parameters serve as input data to model, e.g., erosion, landslides, or soil deformation under shear.
