Inoculant Group B Clovers

Legume Seed Inoculant – Group B Clovers

Inoculant Group: Group B – Clover Group
Rhizobia Strain: Rhizobium leguminosarum bv. trifolii
Suitable For: White Clover, Red Clover, Strawberry Clover, Alsike Clover, Berseem Clover, Cluster Clover, Suckling Clover and related clover species

Legume Seed Inoculant Group B is a specialist rhizobium inoculant used when sowing clover seeds. It helps compatible clover plants form strong root nodules, allowing them to fix atmospheric nitrogen and improve soil fertility naturally.

This inoculant is especially useful when clover has not been grown recently in the paddock, pasture, orchard, vineyard, garden bed or cover crop area. Applying the correct inoculant group can improve establishment, plant vigour, nitrogen fixation and overall soil-building performance.

• Group B rhizobium inoculant for clover species.
• Supports strong root nodulation and biological nitrogen fixation.
• Suitable for white clover, red clover, strawberry clover, alsike clover, berseem clover, cluster clover and suckling clover.
• Helps improve pasture, green manure, cover crop and living mulch performance.
• Useful where clover has not been grown recently or soil rhizobia levels are unknown.
• Can reduce reliance on synthetic nitrogen fertiliser in suitable legume systems.

Application Rates

How to Use

1. Place seed into a clean bucket, tray or mixing container.
2. Lightly moisten the seed with clean water or a mild sticking solution.
3. Add the inoculant and mix thoroughly until the seed is evenly coated.
4. Sow treated seed as soon as possible after inoculation.
5. Keep inoculated seed out of direct sunlight, heat and drying wind.
6. Do not mix inoculated seed directly with fertiliser or chemical seed treatments.

When Should You Use Group B Inoculant?

• When sowing clover into new ground.
• When clover has not been grown recently in the area.
• When planting pasture, green manure, living mulch or cover crop blends containing clover.
• When soil conditions are poor or nitrogen fixation is especially important.
• When you want better nodulation and stronger clover establishment.

Climate and Growing Use in Australia

Group B inoculant can be used wherever compatible clover species are sown in Australia. The inoculant itself is not climate-specific, but clover performance depends on choosing the right species for your region, sowing season, moisture and soil conditions.

• Cool and Temperate Regions: Useful for autumn, winter and spring clover sowing.
• Subtropical Regions: Best used with clovers sown during cooler months.
• Mediterranean / Winter Rainfall Regions: Useful for autumn-sown clover pastures and cover crops.
• Arid Regions: Use where irrigation or reliable rainfall supports clover establishment.
• Tropical Regions: Use only where compatible clovers are suitable, usually cooler highland or dry-season situations.

Storage and Handling

• Store refrigerated where possible.
• Keep out of direct sunlight and heat.
• Use before the expiry date for best performance.
• Do not leave inoculant or treated seed in a hot vehicle or exposed area.
• Sow inoculated seed promptly after treatment.

Important Notes

• Use the correct inoculant group for the legume species being sown.
• Group B is for clovers and related clover species.
• It is not suitable for every legume crop.
• Nitrogen fixation depends on compatible rhizobia, suitable soil conditions, plant health and moisture.
• Poor soil pH, chemical residues, heat, drought or waterlogging can reduce inoculant performance.
