Disentangling atmospheric and soil drought: a new stand‐level manipulation approach for mature forests

open access: yesNew Phytologist, EarlyView.
Design of the VPDrought experiment in a Scots pine (Pinus sylvestris) forest at the Pfynwald research platform. Summary Atmospheric and soil drought are major, yet typically confounded, drivers of tree stress. Rising vapor pressure deficit (VPD) may impair forest function independently of soil moisture decline, yet stand‐scale experimental separation ...
