Using soil ameliorants to improve irrigated canola establishemnt locations

To assess the efectiveness and persistence of soil ameliorants for irrigated canola establishment.

Key messages
  • The ameliorants were applied in 2014, where 3.0 t/ha of gypsum proved to be the most effective in increasing establishment.
  • However all treatments have had no effect in subsequent seasons.
