I would like to inform you about some results of cooperative research on a large-scale field experiment with different traffic intensities. In this experiment during 1984-1989 the effects on soil structure and crop development of different of different field traffic systems were compared. The experimental field consisted of 4 blocks (A-D) of 100 x 212 m each of which carried one crop of a typical four-year intensive crop rotation consisting of potatoes - winter wheat under sown with rye grass - sugar beet- onions. Each block was split into 4 plots of 50 x 100m on which around the year all field traffic was performed with normal "high"- pressure tyres (Treatment H) or with special "low"- pressure tyres (Treatment L). On each block 2 narrow strips (6x100 m) positions between the large plots were allocated to the zero-traffic or bed system (Treatment Z). Soil tillage and all other cultural treatments were the same for all three field traffic systems.
