Salk Institute researchers test deeper-rooted soybeans for carbon storage

Scientists at the Salk Institute for Biological Studies are testing a new soybean variety with deeper roots to help store carbon and withstand climate stress.

Testing root resilience in fields

Researchers hope these plants can survive drought and other climate extremes better than typical crops. They also aim to draw more carbon from the atmosphere and keep it underground. An $18 million grant will support this field testing effort.

Measuring long-term carbon storage

The study must determine how much extra carbon the roots store under real farming conditions. Scientists also need to see how long that carbon remains buried in the soil. Finally, they will check if these crops can maintain their usual yields.
