Lime x molybdenum locations

To compare methods of applying molybdenum and assess the benefits of lime. 

Key messages

There was a 0.6 t/ha response to fertiliser, but no response to molybdenum (Mo) or lime. Plant tissue analysis showed that sodium molybdate (Na2MoO4) was effective applied as a seed dressing or banded with Flexi-N. The high Mo levels in these treatments indicate that application rates were much higher than needed. Grain analysis results confirmed that Mo was not limiting. Grain protein was about 9.0%, hectolitre weights 80 kg/hl, and screenings 3% in all treatments.
