Over the past ten years, Wimmera ryegrass pastures at the Salmon Gums Re- VJ search Station have been improved and maintained by periodic cultivation of the soil even without applications of superphosphate. On heavy crab-holey soil affected by high salt content and unsatisfactory for wheat growing, cultivation treatments have produced remarkably uniform stands of Wimmera ryegrass as shown in the accompanying pictures. The bare patches due to salt, have been largely eliminated. If the interval between cultivations is more than three years Wimmera pastures deteriorate badly.
