New research shows warming temperatures may slow tree root feeding of soil microbes
Dartmouth researchers published a study in New Phytologist explaining how climate warming affects the underground strategies plants use to survive.
Plant roots release carbon compounds
Scientists describe exudation as the process where plants release soluble carbon from root tips. This action feeds microbes in the surrounding soil and makes them more active. Those microbes break down soil to release nutrients for the roots.
Warming climate changes underground systems
Thomas Muratore notes that climate changes profoundly affect trees and other plant life. The study examines how two common tree species respond when conditions underground change. Researchers say understanding these belowground systems is critical for conservation and agriculture.
