Key Messages
- Cereal windrow burning achieved temperatures higher than those which would have resulted in high levels of weed seed mortality, except in paddocks which had 11 mm of rainfall the week before.
- The open paddock burn with a high stubble load had a quicker, faster burn but still achieved the necessary temperatures of 450OC for longer than 60 seconds.
