The advent of sophisticated instrumental techniques and advanced modeling tools has enabled studying soil structure, properties, and emerging functions. Spatially-explicit approaches extend our comprehension of heterogeneously distributed microbial habitats and processes, interactions of organic matter with mineral phases, and element storage. Aggregate structures and the void network of soil systems provides a dynamic scaffolding, which can protect soil components and influence local water retention and elemental distribution. Pedogenetic soil processes drive the differentiation at pedon scale and can result from a combination of small-scale processes determining soil ecosystem fluxes. Across different scale and structures, we look forward to discuss insights from microbial microenvironments via aggregated soil architecture up to the pedon scale.
This session is of interest to soil scientists with complementary biogeochemical and physical backgrounds working at different scales. The session responds to the growing awareness of the importance of spatial heterogeneity and architecture for ecosystem-relevant soil functions, such as the occlusion of organic residues, microbial colonization, provision of water and nutrients, and many more. We aim to present and discuss recent achievements, current obstacles, and future research directions to strengthen our conceptual understanding of the linkage of spatial heterogeneity and soil architecture with soil functions and organic matter dynamics across scales.
