　　This study quantified the impact of soil deformation caused by agricultural vehicle traffic on the anisotropy of the soil pore system and gas transport properties(air permeability,gas diffusivity).An experiment was conducted with five repeated passes of a two-axle self-propelled agricultural vehicle(wheel load 8 Mg,tyre size: 1050/50 R32,tyre inflation pressure: 100 kPa)in May 2014 on an arable clay soil(crop at the time of the experiment: grass ley)in North-Western Switzerland.
