Urea topdressing: importance of timing prior to rainfall, and benefits of Agritain treatment canola at Wirrinya locations
Aims

To further investigate the impact of rainfall timing on the effectiveness of topdressed urea N uptake, and
the possible role of Agritain-treated urea to overcome the problems with the timing of topdressing.

Key messages
  • Agntain was found to provide little benefit for increasing canola yield. Agritain may have a role in reducing urea toxicity to germinating seeds, when crop seeds are sown close to pre-applied urea (especially when large amounts of N are used).
  • This warrants further investigation.
