Aims

To examine the effects of some of the common bed renovation treatments adopted by the farmers, particularly on soil structure, soil water dynamics and subsequent crop performance on beds. 

Key messages

The first-year response of a shallow cultivation treatment (as bed renovation) was not significant and barley yield was marginally superior in the control.  This is in contrast to the results at Gnarwarre where opposite trends were observed, but on a lighter soil. In the heavier Lismore soils, it may be worth looking at the deep ripping option as the higher rainfall compared to Gnarwarre may result in a different soil water use pattern. The shallow cultivation treatment also should be monitored for a further year or two until the system achieves equilibrium.
