- ... A 3-year study on the effect of annual compaction by heavy axle loads was conducted in a loam soil. Each year, loads of 10 and 20 t/axle were applied at two soil moisture contents. The resulting changes in soil bulk density to a depth of 0.6 m and crop response were monitored during each growing season. The loam soil was able to sustain cumulative annual compaction with little structural change du ...

- ... WHEEL traffic is considered a major cause of soil compaction in production agriculture. Soil compaction depends on initial conditions, load, contact area and tire type and shape at the soil surface. The use of tractors equipped with tracks instead of tires has the potential of reducing soil compaction because of reduced surface contact pressure and difference in load distribution over a relatively ...
