Abstract

• X-ray computed microtomography (CMT) imaging of individual soil aggregates is a relatively recent non-destructive approach useful for quantifying intra-aggregate pore responses to environmental conditions controlling their formation and function. CMT can be used to compare intra-aggregate pore geometries with permeability, ion flux, carbon sequestration and many additional soil water flow properties controlling biogeochemistries within soil aggregates. Analysis of 3D porosity, pore size distribution histograms and pore connectivities within soil aggregates from agroecosystem soils will be compared to water retention and hydraulic conductivity measurements. Repeated imaging of the same aggregate following various treatments have been produced by the Advanced Photon Source, ANL and desktop high resolution x-ray CMT scanners. Intra-aggregate morphological changes, identified by commercial and newly constructed algorithms, will be discussed. CMT images of pore geometries will be compared to the organizational configurations of aggregates and their functional contributions to soil hydrology and carbon sequestration potentials in response to different land use and agronomic practices.
