RhizoPulse Lucerne
Ensifer melilotiLive Ensifer meliloti seed inoculant that builds effective, actively fixing nodules for stronger, longer-lasting lucerne stands.
About RhizoPulse Lucerne
RhizoPulse Lucerne is a live biological inoculant containing selected Ensifer meliloti, a bacterium naturally capable of forming a nitrogen-fixing symbiosis with lucerne (Medicago sativa).
After successful infection of the developing roots, the bacteria stimulate formation of specialised root nodules where atmospheric nitrogen is converted into forms the plant can use. The goal isn't simply more nodules — it's effective, actively nitrogen-fixing nodules.
Each pack also includes 1 litre of TrichoSol, AgriBac's Trichoderma-based root protector, for stronger early root growth alongside effective nodulation.
Key benefits
Rapid root colonisation
Places compatible rhizobia close to the emerging root for early establishment.
Effective nodule formation
Supports early establishment of functional, actively fixing nodules.
Biological nitrogen fixation
Allows the crop to access atmospheric nitrogen through its symbiotic relationship with E. meliloti.
Stronger early establishment
Supports vigorous plant development from emergence onward.
Long-term productivity
Good nodulation establishes the biological nitrogen system a productive perennial stand relies on.
How it works
Root recognition
Lucerne roots and compatible E. meliloti communicate through chemical signalling in the rhizosphere.
Root infection
Compatible bacteria enter developing root tissue and initiate the nodulation process.
Nodule development
The plant forms specialised nodules that house the beneficial bacteria.
N₂ fixation
Inside active nodules, E. meliloti converts atmospheric nitrogen into biologically available nitrogen.
Plant growth
The resulting nitrogen supports vegetative growth, protein production and continued forage yield.
Check your nodules
Dig a few plants (don't pull) a few weeks after emergence, wash the roots, and cut nodules open to check activity.
Effective active nodule
Pink or red internally — indicates active nitrogen fixation.
Young nodule
May initially appear pale before becoming fully active.
Inactive / ineffective
Typically white, cream or green internally — not fixing nitrogen.
Mixing & application guide
- Shake well
Mix RhizoPulse Lucerne and TrichoSol thoroughly before use.
- Apply RhizoPulse Lucerne & TrichoSol
Apply both evenly to the lucerne seed while mixing.
- Add DP500
Apply DP500 protectant immediately after the liquid inoculants.
- Mix thoroughly
Ensure uniform coverage of the seed for consistent results.
- Protect the biology
Keep treated seed cool and protected from direct sunlight.
- Plant promptly
Plant treated seed as soon as practical for best results.
RhizoPulse Lucerne and TrichoSol are live biological products — keep cool, do not freeze, and protect from direct sunlight during storage and after treatment.
