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

To look at current techniques used by farmers, or recommended by consultants, to improve medic pastures and determine the most effective method to optimise N2-fixation. Biomass, nodulation and N2-fixation differences between management practices, including inoculation treatments on both sown and regenerating medic stands were measured. The trial also investigated if grazing medic pastures in the break phase of the rotation benefits or impedes nodulation and subsequent N2-fixation.
