Analysis of Changes in Soil Compaction in The Zone Next to Tracks of Agricultural Tractor Passages

Results of investigations on the effect of multiple passages of tractors of various powers (small-medium-large) on soil compaction within the track and the side zone are presented. Changes in specific pressures as a result of variable support area of considered tractor wheels and their sidecompacting action are also presented. There was found statistical significance of the effect of wheel pressures, depth of soil layer and its distance from the track on soil compaction. The investigations were carried out on clayish sand with the use of 3 tractors. Basing on the obtained results a set of empirical equations was developed.
