Precision Agriculture Resources & Tools
Efficient Vineyard Project
This federally-funded project applied precision agriculture tools to address research questions and improve vineyard management practices. The research team developed resources and decision-support tools that are publicly available for industry use in mapping soils, variability in vine growth and crop yield. Learn more about the project here. A grower support tool was created and is outlined below.
- How to create an interactive farm map
- How to use your phone to map your vineyard
- How to work with your vineyard map data
