Grapevine yields and berry quality are influenced by many environmental factors. Plant nutrition is one of the most important of these, and it can be managed by growers.

Symptoms of vine nutrient issues, such as leaf color and shoot growth, are visible in the field. But, it takes skill and experience for field staff to observe visual cues. This is time consuming and often leaves areas of vineyards unnoticed. Sensors attached to field vehicles or drones can find problem areas across more acres.

Our team is developing sensor tools that measure grapevine nutrient status on-the-farm. We are also determining nutrient levels needed by grapevines in different regions. These values will help determine how to fertilize vineyards. We are working with growers from across the US to see if these methods work. This project will help growers to apply precision management in their vineyards.

We hope you explore this website to learn more about the team, our projects across the US, and results. Check out the “News” section for upcoming events where our project results will be featured.
