Abstract
Soil structure is associated with a complex organization of pore spaces playing a fundamental role for soil functioning by governing multiscale interactions of physical, chemical and biological processes. Studying soil processes and their interaction in structured soils is complicated since soil structure is dynamic leading to temporally variable soil functions depending on soil structure evolution or degradation. Investigating pore space dynamics and its relation to soil functions is a challenging task due to the fact that soil pores are organized in three-dimensional networks and the opaque solid soil constituents prevent direct observations of the pore space. This may be overcome by modern non-invasive techniques such as X-ray computed microtomography (XMCT) allowing a detailed description of the internal modification of pore networks upon changes in boundary conditions. This chapter demonstrates the potential use of XMCT in combination with quantitative image analysis procedures to study the effect of hydrologic/mechanical stresses on the evolution/degradation of soil structure in a loess soil as an example.
