Long term disease suppression trial at Streaky Bay locations
Aims

To determine if disease suppression against rhizoctonia is achievable in a grey highly calcareous soil using alternative rotational systems and crop inputs in an upper EP environment and if soil microbial populations can be influenced by rotation and fertiliser inputs.

Key messages
  • The higher input brassica break system had higher cereal yields than the other systems in 2009.
  • Rhizoctonia inoculum levels were higher under the continuous cropping systems compared to the medic pasture and brassica break crops.
  • The different rotations and fertiliser systems have resulted in differences in the microbial community (number) and microbial diversity (their ability to use different sources of carbon).
  • Disease suppression is still the same in all rotations.
