Root length colonization

Average root length per monolith was 32,018 and 51,397 cm for ambient and elevated CO 2 treatments, respectively. For all roots ≤10 mm, average root diameter was significantly smaller in elevated CO 2 plots ( P < 0.001). Average root diameters were 0.72 and 0.57 mm in ambient and elevated CO 2 plots, … See more Plants serve as an important store of terrestrial carbon (C) and have the potential to capture increased C in response to rising … See more A total of 635,313 cm of root length ranging in diameter from 0.025 to 10 mm was sampled from 15 monoliths.
