Welcome

Grape yield and quality is a function of myriad environmental factors. Plant nutrition is one of the most important of these, with the benefit that it can be managed by the grower. 

Visual symptoms of nutrient deficiency can be observed by every grower with some experience; however, that skill is limited to what one can observe over time and space. Remote sensing technology allows us to “see” those symptoms and other indicators of vine stress to help identify problem areas more efficiently and over larger vineyard areas. 

Our team’s goal is to develop grapevine nutrient status measurement tools to pave the way for precision nutrient management in the vineyard. To achieve this, we will work with growers and academic institutions at multiple locations across the nation to determine the efficiency and suitability of proposed methods. We plan to identify better plant-based nutrient management guidelines while also developing these new tools and technologies to make nutrient monitoring more efficient and applicable across larger scales of production. The research team is focused on understanding what is possible with economic and environmental impacts in mind. 

This research was initiated by the National Grape Research Alliance (NGRA) and is funded through the National Institute of Food and Agriculture’s Specialty Crop Research Initiative Coordinated Agricultural Projects (CAP) grant. Project Award Number: 2020-51181-32159.
