Plants Grow Hidden Second Root System – And It’s Helping Fight Climate Change

Scientists discovered that many plants secretly grow a second network of roots more than three feet underground, tapping hidden nutrient pockets and potentially locking away carbon where microbes can’t easily release it. Using deep-core samples from tundra to rainforest, they found nearly one-fifth of ecosystems show this “bimodal” root pattern—upending shallow-soil assumptions and hinting that [...]
