Orvan™ Alfalfa
Alfalfa · Rhizosphere coordination consortium. The coupling consortium, tuned for Alfalfa: amplified nodulation and stronger nitrogen fixation, in a single pass.
Field-proven
- +15.2% yield, up to 6.1× more nodules; 96 sites / 4 regions.
- Amplified nodulation + stand establishment.
How it works
The strains reshape the rhizosphere to improve the nodulation environment for native or co-applied rhizobia, while stronger crop vigor sustains nitrogen fixation through pod fill. In peanut, our research also examines the aflatoxin side of the coupling — how the same shift in the root-zone microbiome relates to Aspergillus flavus, the fungus that produces aflatoxin — in peer-reviewed studies and multi-season OCRI-CAAS field trials.
Where it fits
Orvan™ is a rhizosphere-coordination consortium, not a rhizobial inoculant. It carries no Rhizobium of its own. Applied alongside (or on top of) your rhizobial inoculant, it amplifies the native and co-applied rhizobia already adapted to your soil. Fully complementary to existing programs. Non-GMO; all three strains spore-forming.
How to use
At sowing: Nodu™ ALF seed coat or slurry (Sinorhizobium meliloti); Vigor™ in-furrow or on seed; Orvan™ as the coupled program. Re-inoculate at each reseeding and on high-pH or low-rhizobia soils.
Frequently asked questions
Can I use it with my rhizobial inoculant and fungicide seed treatment?
Yes. At sowing it co-applies with your Nodu™ / rhizobial inoculant and starter NPK. Apply it last, after any fungicide seed treatment; avoid copper fungicides, strong alkali (pH > 9) and chlorinated water (> 2 ppm).
Which formulation should I choose for Alfalfa?
We match the format to your crop, planter and conditions — granule banded with base fertilizer, liquid in-furrow, or an on-seed treatment. Tell us your setup and we’ll recommend the right one.
Do you ship internationally, and what documents are included?
Yes. Each shipment comes with the technical data sheet and a safety data sheet (granule); phytosanitary and import documents are prepared per destination market. Contact us for your country.
How should it be stored, and what is the shelf life?
Store cool, dry and out of direct sunlight; do not freeze liquid forms. Shelf life is formulation-dependent — see the data sheet for the exact figure by format.
Is the product safe and non-GMO?
Yes. All strains are naturally isolated, non-GMO and handled as low-risk (BSL-1). The product is registered with China’s MARA and meets the heavy-metal limits of GB 38400-2019.
