Swedish experiments on subsoil compaction by vehicles with high axle load

摘要: . Soil and crop responses to traffic with vehicles having an axle load of 10 tonnes were studied in 9 field experiments. The clay content the soils ranged from 6 85%. resulted increased soil bulk density strength a depth 50 cm. Compaction effects persisted below plough 7–8 years after traffic. Crop response was negative intensity decreased time. results indicate that maximum loads on arable fields should be less than tonnes, especially soils.
