Frequently asked questions

Does Orvan™ replace my rhizobium inoculant?

No — Orvan™ is complementary and amplifies the rhizobia already in your soil or inoculant.

Is it GMO?

No. All strains are naturally isolated; no genetic modification.

Which crops?

Eight legumes — peanut, soybean, common bean, cowpea, pigeon pea, mung bean, black gram, alfalfa — with multi-site field results on all eight (peanut and soybean have the largest datasets).

Will it work in my region?

Rhizobia are region-specific. Nodu™ is matched to local populations and confirmed before deployment; Orvan™ amplifies your soil’s native rhizobia, so it fits local conditions.

How is it applied?

At sowing — granule, in-furrow liquid, or seed treatment — matched to your planter.

Can I tank-mix it?

Yes with NPK and rhizobial inoculants; apply sequentially with fungicide seed treatments (Orvan™ last). Avoid copper-based fungicides, strong alkali (pH > 9), and chlorinated water (> 2 ppm).

Is it safe? Any residue?

Non-GMO, BSL-1, no synthetic pesticide; no residue concerns under tested conditions.

What’s the shelf life?

12–24 months depending on formulation, stored cool and dry.

Is it organic-approved?

Formulations are made without GMOs, synthetic pesticides, or animal-derived carriers; organic acceptability is jurisdiction-specific (NOP / EU 2018/848 review).

Do you have data?

Yes — peer-reviewed research plus multi-season field trials; full data packages to qualified partners under NDA.

What is a peanut inoculant, and why does peanut need one?

A peanut inoculant is a formulated product that delivers live Bradyrhizobium to the seed or furrow, so peanut (groundnut) roots nodulate and fix their own nitrogen. Nodu™ supplies region-matched rhizobia for that job, and our Orvan™ consortium amplifies those rhizobia to build stronger nodulation and nitrogen fixation — so the crop fixes more of its own nitrogen and you buy less.
