With its Nitrogen fixing nodules on main tap and lateral roots, Lucerne is known of its ability to render Nitrogen to soil. Lucerne thrives best on a deep permeable soil, so it is not normally the first choice for compacted soils.
Perennial Lucerne varieties go dormant over winter and generally survive well unless heaving, waterlogging or icing occur.
Lucerne is high in crude protein and it is grown for grazing and hay forage across temperate areas of the world. The Lucerne plant is resilient because it has a large tap root that can reach deep into the soil, accessing both nutrients and water. It is also an excellent choice for weed control.
