Effect of wheel traffic on soil compaction

At present, increasing tractor number and the wrong application techniques have increased the wheel traffic and the cost of agricultural production. The effect of tractor axle load, inflation pressure of tyre and number of passes on bulk density and penetration resistance of soil was studied. Increasing tractor axle load, the inflation pressure of tyre and number of passes increased the bulk density and penetration resistance of soil to a depth of 200 mm. The greatest amount of soil compaction was found at the first pass. -from English summary
