Precision viticulture is all about identifying and managing variability within vineyards, optimise vineyard performance, in particular, maximising grape yield and quality while minimising environmental impacts and risk. This is accomplished by measuring local variation in factors that influence grape yield and quality (soil, topography, microclimate, vine health, etc.) and applying appropriate viticulture management practices. Precision viticulture is based on the premise that high in-field variability for factors that affect vine growth and grape ripening warrants intensive management customised according to local conditions.
Precision viticulture depends on new and emerging technologies such as Global Positioning Systems (GPS), meteorological and other environmental sensors, satellite and remote sensing, and Geographic Information Systems (GIS) to assess and respond to variability.
