Descripción
The spatial arrangement of soil constituents ?usually referred to as soil structure? controls important physical and biological processes in soil-plant-microbial systems, where microbial population dynamics, nutrient cycling, diffusion, mass flow and nutrient uptake by roots ta- ke place. Those processes are dominated by the geometry of soil structure and a correct model of this geometry is critical for understanding flow and transport processes in soils, creating synthetic soil pore space for hypothesis and model testing, and evaluating simila- rity of pore spaces of different soils. In this communication with characterized the geome- trical morphology of a key element of soil structures: soil aggregates. Soil aggregates were collected at Long Term Ecological Research (LTER) site located in Michigan (USA) and ag- gregate tomography images were obtained on the Argonne National Laboratory (USA). Mathematical morphology and Minkowski functionals were used for image processing and measuring the geometrical attributes of their shape and pore space morphology.
