Orvan™ Soybean
Rhizosphere coordination consortium. The coupling consortium, tuned for Soybean: amplified nodulation and stronger nitrogen fixation, in a single pass.
Field-proven
- +16.1% yield, up to 3.7× more nodules; 253 sites / 18 provinces.
- Nitrogen-fixation potentiation.
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, and no fungus either — all three strains are bacteria. 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 · Orvan™
At sowing, matched to how the product reaches the crop: Base 30–60 kg/ha broadcast or banded with base fertilizer · Root 30–60 kg/ha dissolved in clean water and applied in-furrow through the planter · Coat 2.5 mL/kg seed on the seed, by hand or through a coater. The dose does not change by crop. A live-culture product: with a fungicide seed treatment apply that first, let the seed dry, then Orvan™; apply any rhizobial inoculant after Orvan™. Avoid copper fungicides, agricultural antibiotics, strong alkali (pH > 9) and chlorinated water (> 2 ppm). Blend with fertilizer immediately before application rather than storing a prepared blend. Storage differs by format: the dry formats keep at or below 30 °C with no cold chain and are used within 30 days of opening; Coat is held at 5–25 °C, must not freeze, and is used within 14 days of opening.
The full program · Soybean
At sowing: Nodu™ SY 4–6 g/kg seed; Orvan™ Root (in-furrow) or Coat on seed; co-applies with starter NPK.
Frequently asked questions
Can I use it with my rhizobial inoculant and fungicide seed treatment?
Yes. At sowing it co-applies with your rhizobial inoculant and starter NPK. The order matters: a fungicide seed treatment goes on first and is left to dry, then Orvan™, then the rhizobial inoculant. Avoid copper fungicides, agricultural antibiotics, strong alkali (pH > 9) and chlorinated water (> 2 ppm).
Which formulation should I choose for Soybean?
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.
