Soybean inoculant program (Glycine max)
The world’s most-grown legume and a cornerstone protein and oil crop, with a high nitrogen demand that biological fixation can largely meet.
The challenge
Soybean needs more nitrogen than almost any grain legume; weak or poorly-matched nodulation forces costly fertilizer and caps both yield and seed quality.
50%+ — of a soybean’s nitrogen can come from fixation — with the right, host-specific Bradyrhizobium. Without it, you buy the difference.
The world’s protein crop, and a heavy feeder
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.
Its rhizobia are picky — and often absent
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.
Weak nodulation costs twice
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.
The program
- Nodu™ SY — establishes a vigorous Bradyrhizobium symbiosis
- Vigor™ — builds root and soil health
- Orvan™ — couples nitrogen-fixation potentiation with rhizosphere biocontrol
Field-proven
Across 253 sites in 18 provinces (Heilongjiang, Inner Mongolia, Anhui; 2019–2024): +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.
Rhizobial fit
Soybean is highly host-specific: it requires Bradyrhizobium japonicum / diazoefficiens (USDA 110-type elite strains), not the general tropical group. Nodu™ SY pairs your region with the best-matched soybean strain (essential in fields with no soybean history), and Orvan™ amplifies the established symbiosis.
By product
