Investigating the impact of carbon inputs on disease suppression locations
Aims

To understand the impact of soil carbon and nitrogen cycling on disease suppression.

Key messages
  • Canola in rotation reduced Rhizoctonia inoculum levels and increased following cereal yields.
  • Fluid fertiliser increased plant dry matter and yield on highly calcareous grey soils.
  • A barley/vetch brown manure increased soil mineral nitrogen and this appears to have exacerbated Rhizoctonia disease symptoms on a following barley crop.
  • Added carbon (10 t/ha/yr) has increased microbial respiration and microbial nitrogen.
