Inoculant Group C Sub Clovers

Legume Seed Inoculant – Group C Sub Clovers

Inoculant Group: Group C – Sub Clover Group
Rhizobia Strain: Rhizobium leguminosarum bv. trifolii, strain WSM1325
Suitable For: Subterranean Clover, Balansa Clover, Persian Clover, Arrowleaf Clover and related annual pasture clovers

Legume Seed Inoculant Group C is a specialist rhizobium inoculant used when sowing subterranean clover and other annual pasture clovers. 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 sowing clover into new ground, pasture renovation areas, green manure crops, cover crop blends, orchards, vineyards or paddocks where compatible clovers have not been grown recently. Using the correct inoculant group can improve nodulation, establishment, plant vigour and nitrogen fixation.

• Group C rhizobium inoculant for annual pasture clovers.
• Suitable for subterranean clover, balansa clover, Persian clover, arrowleaf clover and related species.
• Supports strong root nodulation and biological nitrogen fixation.
• Helps improve pasture, green manure, cover crop and soil-building performance.
• Useful where compatible clovers have not been grown recently.
• 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 C Inoculant?

• When sowing subterranean clover or related annual pasture clovers.
• When planting into soil where compatible clovers have not been grown recently.
• When sowing pasture, green manure, living mulch or cover crop blends containing annual clovers.
• When soil rhizobia levels are unknown.
• When strong nitrogen fixation and early clover establishment are important.

Climate and Growing Use in Australia

Group C inoculant can be used wherever compatible annual clover species are sown in Australia. The inoculant itself is not climate-specific, but clover performance depends on species choice, sowing season, moisture and soil conditions.

• Mediterranean / Winter Rainfall Regions: Very useful for autumn-sown sub clover and annual pasture clover systems.
• Cool and Temperate Regions: Suitable for autumn, winter and spring clover sowing.
• Subtropical Regions: Best used with compatible clovers sown during cooler months.
• Arid Regions: Use where irrigation or seasonal 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 C is for subterranean clover and related annual pasture clovers.
• 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.
