Salk Institute scientists are field-testing genetically engineered soybeans with deeper, more vertical root systems designed to withstand drought and lock more carbon in the soil. With an $18 million grant from the Bezos Earth Fund, trials across Illinois, Missouri, Kansas, and Iowa will measure actual carbon sequestration, yield impact, and root durability under real farming conditions. The goal is to see if this trait can scale to commodity crops and contribute to meaningful atmospheric CO2 removal. Early lab estimates suggest one hectare of these soybeans could store an extra metric ton of CO2 per year, but field data is pending. Researchers also hope deeper roots help plants access water during dry spells and reduce fertilizer runoff. However, adoption hurdles remain: seed companies, farmer risk tolerance, and entrenched agricultural systems could slow deployment. The project underscores the gap between promising lab results and practical, large-scale climate solutions.
