Lucerne
Lucerne is a perennial legume and a valuable crop worldwide, with approximately 3.2 million hectares sown in Australia.
Lucerne has a deep taproot which can extract available water from the soil profile and also has high water use efficiency, making it a very drought tolerant species.
Lucerne can fix its own Nitrogen and is proportional to the foliage grown (approximately 25kg N/t above ground dry matter).
While there are some perceived limitations to growing lucerne, sound agronomic advice and practice during paddock selection, preparation, establishment and ongoing management for the life of a stand will go a long way in mitigating many of these.
