Dryland Cropping in Australia
- John F. Angus and
- Anthony J. Good
Until the 1980s, almost all Australian dryland crops were cereals grown in rotation with annual pastures and fallows. Rotations are changing rapidly with intensification of cropping and diversification from cereals to pulses and oilseeds. For the past 140 yr, the area of dryland crops has increased at an annual rate of 3.2% and shows no sign of reaching a plateau. Wheat (Triticum aestivum L.) yields rose 30% during the 1990s after several decades of stagnation. The trigger for the increase was reduced root disease of wheat grown after broadleaf break crops, followed by increased N fertilizer applied to the healthier crops. Australian farmers and agronomists are optimistic that dryland farming systems can become more profitable and sustainable.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
