Plant sensor-based precision irrigation for improved vineyard water use efficiency, grape and wine composition and quality, and vineyard profitability
This project will provide new tools to Australian grapegrowers to schedule irrigation based on real-time measurements of vine water status. Currently, growers schedule irrigation in vineyards using soil moisture sensing (an indirect measure of vine water status and water availability), visual techniques (observing vines for water stress symptoms) or based on weather and/or historical irrigation regimes. These approaches often lead to either over- or under-watering of vines.
This project will build a remote sensing platform to characterise vine-based water status across a vineyard block. Prototype thermal sensors and micro-tensiometers will be developed and the sensors validated against conventional and established methods of vine water status to provide growers with a new platform to continuously measure vine water status and provide real time support to optimise irrigation application in vineyards.
