3. Oklahoma’s Vineyards

4. Precision Viticulture
Branch of Precision Agriculture that was proposed in the early 1990’s
Must maximize yield and quality

5. Vine Vigor
GPS and NDVI
Determines
Harvesting time
Quality

6. Management Zones

7. Irrigation Use of infrared readings of leaf temperature.
Has an effect on time of onset and degree of weight loss.

8. 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

9. Gap Identification Give total area of missing vines
Potential for re-planting

10. Herbicide Application
Identifies and selects weed material at a resolution of < 1 cm2
Permitted a reduction in herbicide application by 85%

11. Selective Harvesting Select high-vigor from low vigor areas
Increases wine quality
Increases retail value
But perhaps the most elegant use of the technology is to mount a GPS device on a tractor, couple it to a computer with GIS software, and then selectively remove cover crops from low-vigor areas of the vineyard, and leaving them in high vigor regions. This is done automatically as the tractor is driven through the vineyard, and can be targeted precisely, row by row.

12. Yield Monitors “On the Go” georeferenced records of yield
Most popular method: Conveyor belt

13. Where is Precision Viticulture going?
Improve mechanical pruning methods
Detect sugar content of the entire field
