Crop application data
The single largest pulse crop (dry beans are about a third of global pulse production) and a daily protein staple across Latin America and Africa.
33%
of the world’s pulse output is common bean — the largest pulse crop, and yet the weakest nitrogen-fixer of the major grain legumes.
Common bean is the weakest nitrogen-fixer among the major grain legumes: it often under-nodulates and leans on fertilizer, and it responds most where native rhizobia are scarce or poorly matched.
Dry beans make up roughly a third of global pulse production and are a daily source of protein across Latin America and Africa — a staple in the truest sense.
Among the major grain legumes, common bean nodulates and fixes the least. Left to itself it under-performs and leans on fertilizer, capturing only a fraction of the nitrogen it could.
The gains are largest on low-nitrogen soils with few or poorly-matched native rhizobia — exactly the fields where a robust, well-matched strain does the most work.
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 · Common Bean · vs. untreated control
Across 62 sites in 6 provinces (Yunnan, Heilongjiang, Inner Mongolia; 2021–2024): +14.2% average yield, up to 4.6× more nodules, nitrogenase up to 5.0×, and up to 60 kg N/ha fixed, with the strongest response on low-nitrogen soils where native rhizobia are scarce.
