The diploma thesis provides an overview of the soil, its composition and attributes. Then, it briefly describes causes of soil solidification and methods of soil cultivation, which eliminate the unwanted soil solidification. This thesis also gives an overview of agricultural tyres, their composition and compression systems. Furthermore, it describes undercarriages of combine harvesters and their advantages and disadvantages. In the practical part of this thesis, there were done laboratory and field measurements of soil solidification after being run over by combine harvesters with different contents of grains in the grain hoppers and using the combine harvester inclination. Subsequently, the measurements were compared and evaluated in terms of changes in the soil porosity
