Partial soil wetting and drying regulate root water uptake in deep-rooted apple orchard

The drought-prone Chinese Loess Plateau (CLP) apple trees have roots that extend deep into the soil. Even when the upper soil layers (0–10 m) are above the permanent wilting point, deep (>10 m) root water uptake (RWU) occurs; the reasons for the deep RWU remain unknown. This stud...
