Abstract

Variable Rate Irrigation to Manage Vineyard Variability in California
Track: Agriculture
Authors: Brent Sams, Luis Sanchez, Nick Dokoozlian, Maegan Salinas

Demand for California wine has been increasing worldwide and production of quality wine grapes must increase to meet the demand. Given the cost of land, production must increase within each vineyard. Soil properties are the main drivers of within-vineyard spatial variability. Yield variability was mapped in a vineyard using harvester-mounted yield monitors. A variable rate irrigation system was deployed to assess the effect of differential watering on the variability of yield and quality.
