Abstract

To date an easy access to regionalise subsoil compaction on the field scale has not been realised with the common soil physical methods. Caused by their own methodical limitation, results can only be produced in the laboratory but with significance limited to the probed soil pit and therefore presenting only a local state of mechanical strength. Existing field methods to access this problem allow simple punctual measurements but are not adequate for a larger spatial resolution. Nondestructive probes, on the other hand, provide a better spatial resolution but in general do not show directly the state of mechanical stress. A solution for this problem could to approach the state of mechanical strength focusing on the stress-at-rest-coefficient, K₀, in combination with various independently measured geophysical values like the apparent electrical conductivity (ECa), the electrical resistivity (ER) and the electromagnetic radiation (EMR). Results from two experimental sites located in the loess belt of Northern Germany showed that all geophysical sensors respond to the higher bulk density and soil water content in the areas of the headland, wheel tracks, and experimental traffic induced overcompaction with higher electrical conductivity or a change in the reflection. A direct correlation to the depth-specific Penetrologger results and the aligned change of the soil stress situation was only possible with the Ground penetrating radar (GPR) and the new soil sensor system ‘Geophilus electricus’. This leads us to the conclusion that the used geophysical based techniques can be used as a pre-screening tool for the detection of the spatial distribution of the subsoil mechanical strength at least in loess-derived soils.
