a pretty small aggregate....
... and CT cross sections along the 3 pronciple axis----
... and 3D reconstruction of the intra-aggregate pore space - the living space of Microorganisms (resolution 0.02 mm/voxel)
Soil sample from top soil of the Chernozem in Bad Lauchstädt (sample diameter 80mm resolution 0.1mm).....
... and the visualized inter-aggregate pore space within an inscribed cube - the living space of soil meso-fauna, supply paths of oxygen and location of fast flow and transport processes.
compacted sub soil (Chernozem Bad Lauchstädt, diameter 80mm resolution 0.1mm). Distrurbance of the structure due to the sampling procedure is evident - we are still improving.
