Acid tolerant lucerne rhozobia: nodulating better at low pH locations
  • To validate the results of the development of a rhizobium strain that is able to nodulate with lucerne at lower pH, as achieved in glasshouse trials.
Key messages

The advantages of lucerne are:

  • Responds to summer rainfall,
  • Deep taproot system to use water and reduce dryland salinity, and 
  • Less nitrogen fertilisers due to nodulation with rhizobia.
