Short summary
At our study site during the experimental period, trunk water was only isotopically similar to root water at 100–160 cm depths. The isotopic composition of root water deviated from that of bulk soil water but overlapped with the composition derived for less mobile water. These findings suggest that the isotopic offset between bulk soil water and trunk water was due to the isotopic mismatch between root water and bulk soil water associated with soil water heterogeneity.
