Session 1: Vine Balance and Precision Viticulture
The concept of balancing vegetative growth and cropping levels for sustained production – is a key organizing principle of viticulture and vineyard management. Growers have lacked the tools to apply this principle on a vine-by-vine basis to manage variable vineyards. New tools are converging to give growers the capacity to address variability through three steps: Measure, Model, and Manage.

Session 2: Measurement
New metrics from sensors, UAVs (Drones), satellites, and analytical technologies are becoming available to growers. What do they measure, and how can growers and buyers use the information?
