Variability of undesirable soil compaction within large plots

Original language description

The main topic of the work was to find relationships between direct and indirect methods of measuring soil compaction and related physical properties. The variability of topsoil properties was evaluated using undisturbed soil samples, cone index, tensileforce measurements and aerial photography. The plot showed variability in all parameters investigated. Nevertheless, during cross-evaluation procedure no significant correlations were found. It was proved that the data from the tensile force measurements and taking aerial pictures have a good predicative ability. By means of continuous measuring of the tensile force and full-area aerial images of the observed field surface, it was possible to obtain a comprehensive data file which was able to show theplot variability at high resolution. However, it is necessary to say, that generally, the final values can be affected by more factors which should be completed with more detailed plot research.
