"CHAMPAIGN, Ill. — Research scientist Ashish Rajurkar kneels in the dirt, lifting a large clod of soil tangled around a soybean plant. He knocks away pieces of earth from the plant’s roots, which slope straight down instead of out to the side like typical soybean plants.
Researchers hope roots like these could help crops withstand some effects of climate change while also drawing more carbon from the atmosphere and storing it underground. Carbon dioxide released by burning fossil fuels traps heat in the atmosphere, driving human-caused climate change.
For years, scientists have explored ways to remove some of that carbon from the atmosphere, including through direct air capture, changes to ocean chemistry so seawater can absorb more carbon, and reforestation. Now, researchers at the Salk Institute for Biological Studies are testing whether deeper root systems could become another tool."
