Building an automation-ready multimodal workflow for comprehensive 3D characterization of intact soil structures.
EMSL Project ID

Abstract
3-dimensional (3D) characterization of intact soil structures (i.e. macro and microaggregates) will provide understandings on how soil physical, mineralogical, biotic heterogeneities control long-term C preservation. We propose a workflow that supports development of an automated capability for solid phase characterization in soils. This workflow uses EMSL multimodal instrumentation for capturing 3D bio-geochemical spatial distribution of the interior volume of a soil aggregate. These soil structures will be used to investigate how chemistry, mineralogy, and porosity controls organic C distribution, water-flow dynamics, and consequently the formation of intra-aggregate microsites/microcosmoses with unique properties, that are usually different from those of surrounding environment.
