symm
Symbiotic microbesThe Science
The health of every crop starts with microbiology.
Symm optimizes this relationship, so your crop grows the way nature intended.
Research backed and field proven.
Plants and soil microbes have partnered since the first roots reached into the ground. Symm builds on that ancient relationship, using well-studied microbes to strengthen the biology already at work beneath your crop.
Every claim we make is grounded in independent, peer-reviewed research and confirmed on working farms. What holds up in the study holds up in the row.
- Peer-reviewed
- Built on independent research into beneficial soil microbes.
- Field-measured
- Tracked on working farms, not just in the lab.
- Two-part biology
- Resilience for the plant and nutrition unlocked from the soil.
The Program
Two inputs, working symbiotically.
One builds the crop's resilience to stress, the other unlocks nutrition from the soil, in a single program for the whole plant.
Part 1
A consortium of Trichoderma harzianum, symbiotic fungi that raise the crop's tolerance to drought, heat and salinity to maintain yield through stress.
Learn more → Nutrition from the soilPart 2
A five-strain Bacillus consortium that unlocks soil nutrients and improves how efficiently the crop uses them.

Reliability, batch by batch.
Biological inputs are only as effective as what actually survives long enough to be applied in field. We test every batch to confirm the live count you’re paying for is what you are getting.
Tested every batch
We check the live microbe count in every batch, so what’s printed on the label is what reaches your field.
Built by scientists
Our formulations are developed and maintained by the microbiologists who study and cultivate these organisms.
Documented lots
Every batch carries its own record. Ask for the certificate of analysis on what you’re buying, and we’ll send it over.
