Will we get herbicide resistant weeds with continuous cropping?
Which crop rotations are the most profitable?
What is happening to nitrogen in the rotations?
What impact does continuous cropping have on soil chemistry and soil water levels?
Key messages
In the past four (dry) years on this demonstration farm the fallow/wheat/oats/lucerne (Phase farming) and wheat/fallow rotations have proved the most financially rewarding, probably due to the moisture storing benefits of fallow.
Urea seems both less risky and more reliable than the pulse or ley in increasing wheat yield.
The extreme dryness has caused problems with weed control (chemicals not effective) and with growth of pulse crops and subclover leys.
