                  Dr. Alfonso Torres-Rua

                  Published in Utah State Engineer – Oct. 2, 2017 – In drought-prone Central California, grape producers are looking for new ways to improve crop production with less water. And it’s not just winemakers feeling the pinch. The citrus groves, nut orchards and alfalfa fields of tomorrow will depend on an increasingly sophisticated toolkit to get the most out of the region’s precious water resources.
