- Trial site, as well as total paddock received foliar Smartrace Magnesium,Smartrace Manganese and Smartrace Zinc all at 1 litre/ha, 1 week prior to plots having applications applied.
- As in previous years, even though some Smartrace Zinc had been foliar applied (at a low rate earlier) the extra spray at 2 litres/ha of Smartrace Zinc, plus all other nitrogen foliar applications increased yield response.
- Yields overall were high compared to a normal season district average.
- N Blast 42, N Blast 42+Zinc Pc, NBH405, Bull Kelp Plus++ all contributed to higher protein levels.
