Stable isotopes of hydrogen and oxygen are used in agriculture to investigate the water sources by crops. Yet, isotopic research on irrigated orchards is still scarce. We investigated variability an apple tree plantation Eastern Italian Alps (South Tyrol) during growing seasons 2020 2021. The orchard was subject irrigation trial, whereby a drip system triggered at different soil potential thresholds two treatment types: full (FI, −30 kPa) deficit (DI, −60 kPa). On bi-weekly basis, we sampled precipitation, river water, groundwater for irrigation. At both FI DI, depths bark-devoid branches, cryogenically extracted their water. Isotopic analyses revealed large differences δ18O values belonging treatments, particularly period (up 8.9‰). In xylem were much smaller 1.6‰).

Abstract The depth‐wise distribution of root water uptake is typically inferred through linear mixing models that utilize knowledge stable isotopes in soil and plants. However, these existing often represent the profile discrete segments, potentially introducing significant uncertainty bias into results. In this study, we introduced a novel model combines Bayesian framework with continuous pattern, named CrisPy. To evaluate performance CrisPy, conducted virtual field‐based tests under several types prior information. CrisPy showed accurate robust reconstruction true various information settings test. By contrast, model, MixSIAR was greatly influenced by deviated from profile. mean squared error proportions ranged 3.6% to 7.4%, while exhibited values 6.3%–15.2%. Furthermore, posterior predictive checking indicated effectively reconstructed standard deviations plant isotopic compositions both tests. MixSIAR, however, underestimated overestimated deviation compositions. These findings collectively support enhanced accuracy, greater robustness, reduced comparison MixSIAR. Therefore, provides powerful tool for partitioning sources.
