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.
Strain discovery
Isolating and characterizing legume-associated microbes from diverse environments.
Consortium design
Combining strains for coupled, multi-functional outcomes that work in synergy.
Formulation science
Delivering live microbes reliably as granule, liquid, or seed treatment.
Field validation
Proving performance across soils, climates, and crop varieties.
Three technologies on one platform.
Each has its own science page; together they form a complete legume program.
Go deeper into the science
Huasheng runs its own R&D across microbiology, plant science, and agronomy — strengthened by a decade-plus research collaboration with the Oil Crops Research Institute (OCRI-CAAS) More on our research history →
Legume-associated strains
Years of joint R&D
Field-trial sites
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.
