Researchers at the Salk Institute are testing genetically engineered soybeans with deeper root systems, aiming to improve drought tolerance and increase soil carbon sequestration. Field trials in Illinois are underway to assess whether these roots can lock away more carbon and withstand extreme weather conditions. The concept is straightforward: deeper roots can pull carbon further into the soil, potentially storing it for longer periods. If the trait proves effective, it could offer a low-cost way to remove atmospheric carbon while helping crops survive climate stress. However, questions remain about scalability, yield impacts, and long-term carbon accounting.
