Long term disease suppression trial at Streaky Bay locations
Aims

To determine if disease suppression against rhizoctonia is achievable in an upper EP environment on a grey highly calcareous soil using different rotations and cropping inputs.

Key messages
  • Changing rotation and nutrition have changed the microbial population activity and diversity but not developed disease suppression after seven years.
  • One year of wheat in 2009 resulted in high Rhizoctonia inoculum regardless of previous rotation or fertiliser histories.
  • Take-all has increased in the continuous cereal district practice treatment to severe levels; higher nutrition treatments give the plants the ability to cope better with these increased disease levels.
  • The high input systems have continually yielded higher than the other systems, but inputs of N have not matched production levels completely so soil reserves of mineral N are now lower in these treatments.
  • In good seasons the high input treatments have shown that district practice performance is severely limited by inadequate nutrition.
