Vigor™: PGPR & soil-health inoculants.

Vigor™ — PGPR: phosphorus & stress. Stronger roots. More available phosphorus. Tougher crops.

A plant-growth-promoting rhizobacteria (PGPR) consortium of Bacillus subtilis, Pseudomonas fluorescens, Bacillus megaterium (phosphate-solubilizing), and Azospirillum brasilense that builds root systems, unlocks bound soil phosphorus and potassium, and improves drought and salinity tolerance.

How it works

Phosphate- and potassium-solubilizing strains release nutrients already locked in the soil; auxin (IAA) production drives root proliferation for better water and nutrient capture; ACC-deaminase activity buffers drought and salinity stress; associative diazotrophs add a modest nitrogen contribution.

Where it fits

Vigor™ is the PGPR layer of the program. It does not form nitrogen-fixing nodules itself (that is Nodu™’s rhizobial symbiosis), but it unlocks bound soil phosphorus, drives root growth, and buffers drought and salinity stress.

Strains

Bacillus subtilis (root colonization), Pseudomonas fluorescens (phosphate solubilization & biocontrol), Bacillus megaterium (phosphate solubilization), and Azospirillum brasilense (Ab-V5 / Ab-V6-type; auxin + ACC-deaminase for stress tolerance). PGPR are not host-specific: one broad-spectrum formula serves all eight legumes (no crop-specific SKU).

Field-proven

  • Across 180+ trial sites: solubilizes bound soil phosphorus, cutting applied P by up to 25% at equal yield.
  • +12% root biomass and more uniform, vigorous establishment.
  • +8.1% average yield (higher on low-P, low-input, or stressed soils), with better stand and faster recovery under drought and salinity.
