Do grape cultivars have different responses to nutrients? Do we need to sample different tissues based on cultivar? Does the time of day matter for tissue sampling? In this episode, Dana Acimovic of Virginia Tech's Viticulture Team describes the research to address these questions. Podcast transcript and details are available at http://beav.es/5GD.

Foliar nitrogen application is one way wine grape growers can improve berry and must yeast assimilable nitrogen (YAN). In this episode, Pierre Davadant, graduate research assistant in Dr. Markus Keller’s Lab at Washington State University, describes his research to trace the destination of nitrogen through grapevines, with a focus on foliar nitrogen applications. Listen to find out where nitrogen ends up! Podcast transcript and details are available at http://beav.es/5GD.

We know nitrogen is important for a healthy fermentation, but does the source of nitrogen matter? Should it be added in the vineyard or the winery? In this episode, Megan Mershon, graduate research assistant at Virginia Tech, describes research they are conducting to compare wine sensory response from nitrogen trials they’ve conducted in the HiRes Vineyard Nutrition Project.

Working with crop specialists is important for precision ag tool development. In this episode, Dr. Manoj Karkee talks about his team’s collaboration with others in the HiRes Vineyard Nutrition Project to develop ground-based sensors for vineyard nutrients. He also talks about other projects to make farming more efficient, including shoot thinning and crop yield estimation. Podcast transcript and details are available at http://beav.es/5GD.
