Dual-isotope tracer experiment (2H, 15N), 2023

Isotopic data associated with the publication "De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees" by Klara Mrak, Christina Hackmann et al.
A dual-isotope pulse-chase tracer experiment was conducted in two temperate forests in Germany. Tracer solution enriched in 2H and 15N was applied at 60 cm soil depth or below the litter layer. Uptake of the tracer by neighboring mature forest trees was tracked over time (4, 5, 6, and 14 weeks after labelling) by sampling xylem water and foliage of the target trees.
