Continuous cropping - is it sustainable? locations
Aims

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.
