Symbiotic microbes

Stronger crops, acre after acre.

Two living microbial inputs that raise yield, bring fungi selected for drought and heat tolerance, and help the crop access more of the nutrients available to it.

The Science

The health of every crop starts with microbiology.

Symm optimizes this relationship, so your crop grows the way nature intended.

Research backed and measured in the field.

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.

What holds up in the study holds up in the row.

Peer-reviewed
Built on independent research into beneficial soil microbes.
Two-part biology
Resilience for the plant and nutrition unlocked from the soil.

Two parts, one program.

Two living blends, each with a distinct job, run together as a single program for the whole crop.

Resilience from within

Part 1

Stress resilience
Contains
  • Trichoderma harzianum
A consortium of advanced strains

Part 1 is a living consortium of advanced Trichoderma harzianum strains, symbiotic fungi that partner with the plant itself. They were selected for drought and heat tolerance, an added benefit not counted in our yield figures.

  • Built for tough seasons. Part 1's fungi were selected from plants that thrive in hot, dry ground, and peer-reviewed research shows this kind of fungus helps seed and seedlings tolerate drought and heat.
  • A consortium, not a single strain. A blend of advanced strains covers far more conditions than any one microbe can, which is what sets it apart from off-the-shelf, single-strain products.
  • Sets up the season. More resilient, better-supported plants lay the groundwork for the rest of the season. In our own seedling studies, treated seed germinated faster and more completely, including after drought.

Nutrition from the soil

Part 2

Nutrient-use efficiency
Contains
  • Bacillus licheniformis
  • B. megaterium
  • B. pumilus
  • B. subtilis
  • B. amyloliquefaciens
Five-strain consortium
~1×10⁸ CFU/g each

Part 2 is a five-strain Bacillus consortium, beneficial bacteria that unlock nutrients already present in your soil and help the plant use them more efficiently. The result is more of what is already there reaching the plant.

  • Unlocks your soil. Five complementary Bacillus strains free up nutrients and minerals that are present but out of reach, putting them back to work for the crop.
  • Compounds with Part 1. A more resilient crop makes fuller use of what Part 2 unlocks, which is why the two are always run together as one program.

Always sold together as one program. One protocol, two parts.

How it works

Simple to run.

01

Order the program

Set your acreage and order online. Both parts ship together, matched to your coverage.

02

Apply the two parts

Both parts apply the same way, at seed, in-furrow, or as a foliar spray, on your normal schedule.

03

Grow and measure

Track your yield across the season, side by side against an untreated strip on the same field.

Reliability, batch by batch.

Biological inputs are only as effective as what actually survives long enough to be applied in field.

01 · Formula

Built on microbiology

Symm’s living organisms are studied and cultivated by microbiologists who specialize in them, living biology, not synthetic chemistry.
