Controlled traffic: will it improve yields in the LRZ? A case study on deep sand locations
Aims

To determine the effects of machinery trafficking on soil properties and crop performance on a deep sand in the LRZ of south-eastern Australia.

Key messages

• Multiple machinery pass trafficking decreased crop yields for at least four years on a Loxton deep sand.
• Single pass machinery trafficking did not result in yield decreases at Loxton and rarely at any of the other trafficking soil types in this project.
• Most soils in the south-eastern Australian Low rainfall zone are not likely to remediate from compaction naturally.
