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.
From strain to field: how our legume inoculants are developed and evaluated
Strain discovery
Isolating and characterising legume-associated microbes from diverse environments.
Consortium design
Combining complementary strains into multi-functional consortia that work together.
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 programme.
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 →

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.
