Optimization of Irrigation of Wine Grapes with Brackish Water for Managing Soil Salinization

Land, 2023
Water scarcity and quality are critical impediments to sustainable crop production. In this study, HYDRUS-2D was calibrated using field measurements of water contents and salinities in the soil under wine grapes irrigated with river water (Rw, 0.32 dS/m).
