Aims

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

Key messages
  • Proper rotations (irrespective of tillage methods) incorporating no more than two cereal crops in sequence with the addition of either a break crop or a fallow once in every three years is ideal. This rotation allows a very productive and sustainable farming system in our environment.
  • The most profitable system since 1999 has been two years of cereal followed by a break crop such as peas under no till.
  • No till systems are now becoming more profitable in the trial than cultivated systems under every rotation.
  • No till will work on our problem soils so long as effective weed control is achieved.
  • Under a continuous cereal rotation, the impact of weeds, diseases, poor nutrition and subsequently lower yields has lowered profitability
