Driven by science

The Huasheng legume microbial platform.

The technical background of the legume inoculant products Nodu, Vigor and Orvan, with their crop-specific records and scientific context.

The technical development and evaluation framework for these legume inoculant products.

01

Strain discovery

Isolating and characterizing legume-associated microbes from diverse environments.

02

Consortium design

Combining strains for coupled, multi-functional outcomes that work in synergy.

03

Formulation science

Delivering live microbes reliably as granule, liquid, or seed treatment.

04

Field validation

Proving performance across soils, climates, and crop varieties.

Regulatory-grade documentation

Every technology, every legume crop.

All three lines serve every crop. Nodu™ is crop-specific (rhizobia are host-specific); Orvan™ ships as crop-tuned editions on one core consortium; Vigor™ is a single broad-spectrum formula. Peanut and soybean carry the largest datasets.

Strain work in the laboratory: isolation, identity verification and purity testing before anything is scaled.
Fermentation. Cell count and viability are what a live product is finally sold on.
Roots lifted from a treated plot — where the laboratory work is either confirmed or it is not.
