Crop application data
The world’s most-grown legume and a cornerstone protein and oil crop, with a high nitrogen demand that biological fixation can largely meet.
50%+
of a soybean’s nitrogen can come from fixation — with the right, host-specific Bradyrhizobium. Without it, you buy the difference.
Soybean needs more nitrogen than almost any grain legume; weak or poorly-matched nodulation forces costly fertilizer and caps both yield and seed quality.
Soybean is the most-grown legume on earth and a cornerstone of the world’s protein and vegetable oil — but it demands more nitrogen than almost any grain legume, and that demand has to be met somehow.
Soybean nodulates only with specific Bradyrhizobium japonicum (elite USDA 110-type strains), not the general soil rhizobia. On ground with no soybean history the right partner simply isn’t there, so the crop can’t fix and leans on fertilizer.
Thin or poorly-matched nodulation forces expensive nitrogen and still caps yield and seed quality — the protein and oil the crop is grown for. You pay more and harvest less.
A crop-matched program led by the Orvan™ coupling, backed by a region-specific rhizobium (Nodu™) and phosphate-solubilizing, stress-tolerance PGPR (Vigor™). Each is field-proven and available on its own.
Rhizosphere coordination consortium
Nitrogen-fixation potentiation — applied alongside your rhizobial inoculant. Orvan™ carries no rhizobia of its own; it amplifies the ones already adapted to your soil.
Rhizobial inoculant
The region-matched, nitrogen-fixing rhizobia your crop needs — so it fixes more of its own nitrogen and you buy less.
PGPR — phosphorus & stress
Frees bound soil phosphorus, builds stronger roots, and buffers drought and salinity stress — the second leg of the consortium.

Orvan™ field trials · Soybean · vs. untreated control
Across 253 sites in 18 provinces (Heilongjiang, Inner Mongolia, Anhui; 2021–2025): +16.1% average yield, up to 3.7× more nodules, nitrogenase up to 4.8×, and elevated isoflavone content. A strongly-nodulated soybean crop can fix 100–200+ kg N/ha, supplying over half its nitrogen.
