Precision irrigation of grapevines
Dr. Jean-Jaques Lambert, Specialist in Soil Science , Department of Viticulture & Enology, UCD
Reduced deficit irrigation (RDI) is practiced in a number of vineyards producing fruit for premium wines, in order to control yields and enhance quality. Vines are robust plants that can still produce quality fruit with reduced soil water availability. However, many vineyards still use more water than needed in order to increase yields, especially in vineyards for production of moderately priced wines. The current California drought is forcing a re-evaluation of current crop irrigation practices. A review of current winegrape irrigation principles and practices will be presented. An ongoing Oakville station project (Napa Valley) will be discussed.
Dr. Jean-Jaques Lambert earned his PhD in Soil Science at UC Davis and is a Certified Professional Soil Scientist (CPSSc) of the Soil Science Society of America. He has worked on soil analysis and mapping projects in California, Spain and France; while in France he worked for three years at the National Agronomy Institute (INRA) in Orleans. He specializes in soil-vine relationships, vine nutrition, rootstock choices and vineyard variability management, especially with respect to irrigation.
