Manage ground cover with lucerne-grass mixes

Lucerne is the most widely sown and adapted perennial legume on the Northern Slopes of NSW, but has fallen from favour in recent years. One reason for lucernes decline is its potential when grazed for low ground cover and associated high risk of surface runoff and erosion. Lucernes poor performances in variable rainfall years, low growth in winter, and potential for bloat in cattle are also issues.

Research conducted at Tamworth EverGraze Proof Site addressed this issue with lucerne-grass mixes.  The research showed that pastures with a mixture of lucerne and tropical perennial grasses have potential to increase total dry matter production and spread its distribution more evenly through the year, thereby reducing feed gaps and providing greater resilience in variable seasons.  Ground cover of the lucerne-grass mixes was able to be maintained above the minimum benchmark of 70% most of the time, where in a pure lucerne stand, ground cover dropped to as low as 20%.  Full details of this work can be found here.
