| Abstract: | The relationship between the strength of field soils, under grass ley or winter wheat, and soil water suction was monitored over an 18 month period. The soil types selected for this investigation represent a range of agricultural soils commonly found in central and eastern England. Results are presented which show that a strong correlation exists between soil strength and soil water suction. This relationship was found to be dependent on soil type, soil bulk density and type of vegetative cover. Critical soil water suction limits for predicting the trafficability and workability of the soils are presented. These can be used in conjunction with data from tensiometers to assess the status of field soils, repeatedly and non-destructively, at fixed points within fields. |
