Salk Institute, with an $18 million grant from the Bezos Earth Fund, is moving its ROOTS project into field testing. The three-year effort will develop soybean varieties with deeper, more carbon-rich roots that can store more soil carbon and better withstand drought and disease. The research builds on earlier work that identified 347 gene candidates tied to root traits. The project uses an AI platform called RootGPT to speed up trait discovery and will run field trials in Illinois and the Midwest. Salk estimates that enhanced root traits could remove 1 to 2 metric tons of CO2 per hectare per year if they perform as modeled. The goal is to give farmers crops that are both resilient and climate-friendly, and to create evidence for long-term soil carbon storage that could support carbon credit markets.

Soil carbon credits depend on measurable, durable storage. This project is testing that in the field with soybeans. If the numbers hold, it could make ag carbon credits more credible.

RootGPT sounds interesting, but the real test is whether farmers see value. If these traits also improve drought tolerance, adoption gets easier.

Three years is short for field trials. The modeling says 1-2 tCO2/ha/yr, but that's optimistic until we see multi-year data. Also, what about the cost of seed and any yield trade-offs?

Salk gets $18M from Bezos Earth Fund to field-test deeper-rooted soybeans for carbon storage. AI platform RootGPT will speed up trait discovery. Worth following.

For soil carbon to count, you need clear measurement and verification. This project could provide evidence, but the policy framework for paying farmers for soil carbon is still thin.

The suberin angle is smart. Slow decomposition means longer carbon residence. But farmers need to see a yield benefit or payment. That's the real bottleneck.
