Which statement best defines precision viticulture?

• A. Makes use of data collected from the vineyard to respond to changes from plot to plot and from row to row
• B. Uses uniform inputs across the entire vineyard
• C. Ignores soil variability
• D. Focuses only on irrigation management

Answer: (A)

Precision viticulture is the practice of managing a vineyard based on spatial variability, using data collected from different parts of the vineyard to tailor actions to specific zones. By mapping factors such as soil properties, moisture, vine vigor, and yield, decisions about inputs like water, nutrients, canopy management, and pest control are made row by row or plot by plot. This approach ensures resources are applied where needed and in appropriate amounts, improving quality and efficiency while reducing waste.

Why this best fits: it emphasizes acting on data-driven differences within the vineyard, rather than treating the whole site the same. The other ideas describe uniform input application, ignoring variability, or limiting focus to irrigation alone, which do not capture the broader, data-informed, site-specific management central to precision viticulture.
