Identifying the causes of unreliable N fixation by medic based pastures

To assess the impact of soil nutrition, current herbicides, adjuvants and rhizobial inoculants on nitrogen (N) fixation by medics under field conditions typical of the upper Eyre Peninsula.

Identifying the causes of unreliable nitrogen fixation by medic based pastures

The broad aim of this 3 year SAGIT funded project was to investigate if current management tools for medic based pastures, such as herbicides, fertilisers and rhizobial inoculants, are affecting N fixation by medic pastures under field conditions typical of the upper Eyre Peninsula.

Improving medic pastures in low rainfall mixed farming systems - how to get the most ‘free’ N

To investigate the impact of grazing, soil nutrition and rhizobial inoculants on dry matter production, nodulation and N2-fixation of a regenerating medic pasture under field conditions.

Maximising dry matter production for grazing systems on alkaline soils

To identify plant varieties or mixtures that can increase dry matter production of the pasture break phase on the highly alkaline soils of upper Eyre Peninsula. Current cropping and grazing systems are mostly based on monocultures and the potential feed base of the break phase could be broadened to be more productive for grazing and available for a longer time period in the season. Current oat varieties, mixed break crops and newer pasture species were trialled at Piednippie in 2018 to investigate whether a more productive and prolonged feed base is possible.
