N2 - It is possible the commonly used practice of deficit irrigation could affect the movement of nitrate to the root surface, and subsequent uptake of nitrate in grapevines. A sensor which measures both soil moisture and EC concurrently, the TriSCAN sensor (Sentek Sensor Technologies) was evaluated in a drying soil system. Data from the TriSCAN sensors and leaf nitrate levels were then used to study the relationship between deficit irrigation and nitrate dynamics in the rootzone of grapevines. The TriSCAN sensors were arranged in arrays of 12 sensors per dripper and the data used to generate figures which clearly show changes in the distribution of EC in the soil root zone associated with fertigation, leaching and uptake of nutrients by the vines.
