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.
