Tools, Tech and Strategies for Vineyard Irrigation
EXPERTS DISCUSS METHODS TO EVALUATE VINE WATER STATUS
By Ted Rieger
A recent seminar at the University of California, Davis (UCD) on
vineyard water management included presentations from water
management experts, researchers and suppliers who provided
an overview of sensors, technologies and management practices
used in vineyard irrigation. The important questions a grower
needs to answer in irrigation management:

MEASURING AND MONITORING WATER STATUS

include vine visual inspection, historical site data based
on seasonal weather and vine development patterns, and
technologies and sensors to monitor and measure vine water
status and stress. Some common technologies and sensors
include soil moisture sensors, using a pressure chamber (pressure

on individual vines, and climate-based information to monitor
vineyard evapotranspiration (ET).
Every monitoring system has limitations. Some systems may
provide more useful data based on the vineyard site, soils
and climatic conditions. Cost and ease of use are other factors
