To answer the question - continuous cropping - is it sustainable?
Key messages
Many views exist as to whether continous cropping is sustainable.
Results from a long term tillage trial at Condobolin indicate direct drilled crops are outperforming crops using tillage.
Stubble retention compared to burning gives mixed results for yield, although more weed build up is evident with retained stubble.
Wheat yields are higher when grown after peas than after wheat in succession.
