摘要：

Trafficability tests with typical farm vehicles were carried out on 3 lowland fields at various degrees of wetness. Structural damage after the first and third passes was assessed in terms of bulk density, aeration porosity, pre-size distribution and rut depth. Critical water table limits for trafficability were 53, 45 and 60cm for Lumbum muck, Hallar silty clay loam (grassland), and Hallart silty clay loam (cultivated) respectively. -from Authors
