Precision Agriculture In Viticulture By Pam Turner
Vineyard Information Area Dedicated to Wine Spain 11,750 km² France 8,640 km² Italy 8,270 km² Turkey 8,120 km² United States 4,150 km² Iran 2,860 km² Romania 2,480 km² Portugal 2,160 km² Argentina 2,080 km² Australia 1,642 km² • Production • 71% wine • 27% fresh fruit • 2% dried fruit • Vineyards • 2% Yearly increase
Precision Viticulture • Branch of Precision Agriculture that was proposed in the early 1990’s • Must maximize yield and quality
Vine Vigor • GPS and NDVI • Determines • Harvesting time • Quality
Irrigation • Use of infrared readings of leaf temperature. • Has an effect on time of onset and degree of weight loss.
Vine row interaction • NDVI vineyard • Extracted Rows (yellow) Background (blue) • Must delete non-representative plants and vegetation • Ensures health and vigor of vines • Aids pruning process
Gap Identification • Give total area of missing vines • Potential for re-planting
Herbicide Application • Identifies and selects weed material at a resolution of < 1 cm2 • Permitted a reduction in herbicide application by 85%
Selective Harvesting • Select high-vigor from low vigor areas • Increases wine quality • Increases retail value
Yield Monitors • “On the Go” georeferenced records of yield • Most popular method: Conveyor belt
Where is Precision Viticulture going? • Improve mechanical pruning methods • Detect sugar content of the entire field
