  "abstract": "Vineyards in Marlborough, New Zealand, maintain dense canopies and rely heavily on drip irrigation to produce aromatic white wines in the rain-shadowed valleys. Although irrigation water is available from groundwater, its level is slowly but steadily decreasing, indicating the need to improve irrigation efficiency and soil water management to sustain viticulture. In this study, we measured grapevine water uptake depth across seven representative soil types in the region and related them to soil properties and soil management to inform more sustainable practices. Soil texture explained most of the observed variability among the seven study sites. Isotopic analysis of water (δ¹⁸O and δ²H) and Bayesian mixing models (MixSIAR) showed soil-dependent differences in water uptake depth. Analysis of berry carbon isotopes (δ¹³C) indicated that, despite site-specific differences in soil type and soil management, grapevines experienced low water stress across all sites. Together, these results demonstrate that grapevine water uptake depth reflects soil physical properties, with implications for soil type-specific water management and irrigation strategies.",
