Crops that hold their yield when the soil fights back
We screen Patagonian extremophile microbes with AI to find biostimulants that keep grains, legumes, and vegetables productive under salt stress and cold. For growers farming hard ground.

Salt and Cold Are Writing Off More Farmland Every Season
Irrigated land accumulates salt. Frost windows are shifting. Growers who worked the same plots for generations now face seasons where the soil itself is the threat. Synthetic inputs address nutrition, not stress tolerance at the root level.
Saline Soil Pressure
Salt accumulation in irrigated farmland is accelerating across several major grain-producing regions. Osmotic pressure at the root interface limits water and nutrient uptake even when inputs are present.
Cold Stress and Frost Events
Late-frost frequency is rising in high-altitude growing regions. Cold-shock at seedling emergence is one of the highest-impact yield loss events, and there are few biological tools that help at that stage.
From Extreme Soil to Practical Crop Input
Three steps that connect the harshest soils on earth to inputs growers can actually use.
Sample from Extreme Environments
We collect soil cores from Patagonian salt flats, frost-prone volcanic steppe, and hypersaline lagunas. Microbes that thrive there have stress-tolerance mechanisms encoded in their genomes.
Screen Thousands of Isolates with AI
Our genomic scoring platform queries thousands of isolate genomes for stress-tolerance gene families: halotolerance clusters, cold-shock protein induction, ACC deaminase activity. AI narrows thousands to dozens.
Validate in Greenhouse, Then Field
Shortlisted candidates go into controlled stress-chamber assays and greenhouse trials before any field application. We only advance strains that show measurable crop benefit under simulated stress conditions.
What the Data Shows So Far
Results from our internal greenhouse assays and early-access pilot. Small sample sizes; we present them honestly.

"We applied the candidate inoculant on a 40-hectare saline test plot alongside our standard variety. The treated rows showed noticeably stronger stand establishment and the agronomist called it the most promising trial input of the season."

Each strain is sourced from a different extreme-environment context, targeting a distinct stress mechanism relevant to current growing conditions.

DiscoveryBuilt for Growers and the Companies That Supply Them
For Growers
Farming saline or cold-stressed land means every input decision carries more risk. We are looking for growers ready to run early-access trials on a defined plot area alongside their standard practice.
- Seed treatment and foliar application formats
- No changes to existing agronomic program required
- Data shared back to inform your next season
For Agricultural Input Companies
Our discovery pipeline produces validated candidates with defined stress-tolerance mechanisms. If you formulate biostimulants or are expanding into the biological crop input space, we have data to share.
- Greenhouse validation data available for review
- Licensing and co-development conversations welcome
- Strain collection sourced from distinct ecological niches
