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
  • Differences in C input (dry matter production plus any additions) between the treatments were 24 t/ha at Minnipa, and 31 t/ha at
  • Poochera over the last two seasons.
  • Wheat at Minnipa produced between 0.5 t/ha of stubble in a poor season (2008) and 8.8 t/ha in a good season (2009).
  • Doubling the seeding rate of wheat at Minnipa produced 1.4 t/ha extra stubble compared to the wheat control in 2009.
  • Barley and vetch brown manures produced the lowest dry matter at both sites.
