Salk Institute's ROOTS Project Tests Deeper-Rooted Soybeans for Soil Carbon Storage

The Salk Institute is moving its deeper-rooted crop research from the lab into field trials. A new $18 million grant from the Bezos Earth Fund will fund the three-year ROOTS project, which tests whether soybean varieties with deeper, stronger roots can store more carbon in soil and better handle drought and disease. The project builds on an earlier $30 million grant that helped Salk identify 347 gene candidates tied to carbon-storing root traits. Salk scientists will use an open-access AI platform called RootGPT to speed up trait discovery, then validate results through lab, greenhouse, and field studies. Field trials in Illinois and the Midwest will measure whether the Salk Ideal Soybean varieties can add 1 to 2 metric tons of carbon dioxide removal per hectare per year compared to conventional varieties. The project also evaluates how the soybeans perform under stress, since farmers will only adopt climate-focused crops that hold up in real growing conditions. If the trials succeed, the same root trait strategies could later be applied to maize, rice, and wheat. Salk is working with its spinout company Cquesta to move promising varieties from research into commercial pipelines.

Good to see Salk's root research finally moving from the lab into field trials. The $18M from Bezos Earth Fund covers three years of testing whether deeper soybean roots can actually store more carbon in soil. The 1 to 2 tons per hectare per year figure is still a model estimate, so the field data will be the real test.

The measurement side is going to be the bottleneck. Soil carbon changes slowly and field sampling is noisy, so proving a few tenths of a percent shift is hard. If these trials produce solid MRV data, it makes a future ag carbon methodology much more credible. Without that, the tonnage numbers stay marketing.

Three years is a short window for soil carbon. Roots can push carbon deeper, but you need multi-year data to show it stays there and doesn't just cycle. I also want to see yield numbers under normal farm management, not just controlled stress trials. If the deeper roots cost yield, no farmer is planting them.

Exactly. Farmer adoption will decide this, not the greenhouse results. The drought and disease resistance angle is what gets farmers interested. Carbon storage is a bonus that might pay later through credits, but it won't be the reason a soybean farmer switches varieties.

The RootGPT part is worth watching too. Open-access AI trained on gene, root, and soil data could speed up trait discovery for other crops like maize, rice, and wheat. The soybean work is the proof of concept, but the platform is where the long-term value might sit.
