Aims

To investigate the sustainability and profitability of cropping rotations and tillage methods on
Merriwagga soils.

Key messages
  • Long term gross margin data shows conventional tillage to be more profitable than minimum tillage.
  • Long term gross margin data also shows that continuous wheat and rotation l are the most profitable rotations.
  • No-tillage into a long fallow situation is significantly less profitable than conventional tillage, by $147.oo/ha. This is not the case with no tillage into a stubble situation which is not significantly different to conventional tillage.
  • A major factor determining the profitability of the no tillage treatment is effective weed control.
  • The threat of root diseases, such as Rhizoctonia, is now at a high risk level in the continuous wheat rotation, particularly under no tillage, whereas the risk is minimal in other rotations.
