Vineyard to Winery - Looking Beyond YAN

HiRes Vineyard Nutrition Podcast ·

2023/06/20

Vineyard nutrient management often focuses on nitrogen which is important for berry and must nitrogen that feed the fermentation. However, there is more that we need to learn about nitrogen in wine. In this episode, Dr. Amanda Stewart, Associate professor in the Department of Food Science and Technology at Virginia Tech, talks about her research to understand the components of nitrogen that lead to sensory impacts in wine and ciders.

Defining Economic Value of Vineyard Nutrient Management

HiRes Vineyard Nutrition Podcast ·

2023/04/18

Economic sustainability is important to all farm operations. How do we determine economic value of nutrient management in the context of the larger production system or into the future? Dr. John Woodill, Research Associate at Oregon State University’s College of Earth, Ocean, and Atmospheric Sciences, describes how econometric research explores farm production, yield, and climate data to understand the impact of mineral nutrition through models developed from and informed by that data.

Vineyard Data and Experience Required for Sensor...

HiRes Vineyard Nutrition Podcast ·

2023/03/21

What is required for sensor development? In prior episodes we heard from researchers describing what is possible with sensors using “off the shelf” technology. In this episode, we discuss fitting that technology for grapevines, which requires a lot of vineyard data. Learn about sensor development history and applicability for nutrient sensing from Dr. Qin Zhang, Professor of Agricultural Automation at Washington State University.

Honoring the Past, Building the Future

HiRes Vineyard Nutrition Podcast ·

2023/03/07

We return to the question of tissue nutrient sampling during this episode to explore how the classic petiole testing methods are being compared to new leaf sampling and testing at the individual and whole-canopy level in California table grape trials. Learn how viticulture and sensor research developments have the potential to build upon current methodology to inform future nutrient monitoring and management from Dr. Mathew Fidelibus, Extension Specialist, University of California – Davis.

Precision Tools for All Vineyards, Great and Small

HiRes Vineyard Nutrition Podcast ·

2023/02/21

Many growers believe that precision agriculture tools are either not necessary or not accessible due to cost or lack of economy of scale. Learn how sensor technology is being developed for nutrient tracking across vineyards of all sizes from Dr. Alireza Pourreza, agricultural engineer and Cooperative Extension Specialist at UC Davis.

2023/02/07

Vineyard nutrient management varies by region and grape market. In New York, juice and wine grape vineyards are grown in different regions and have different production goals, both of which influence the grower’s nutrition monitoring and management. Learn more about how growers in these sectors manage nutrition from Dr. Justine Vanden Heuvel, Viticulture Professor at Cornell University.

It's All About Integration

HiRes Vineyard Nutrition Podcast ·

2023/01/24

Precision agriculture has been slow to make its way into vineyard production. The technologies seem too good to be true or out of reach for many growers. Dr. Terry Bates, Senior Research Associate and Director at Cornell AgriTech's Lake Erie Research and Extension Lab, describes his research to make precision tools accessible to growers, using the “measure, model, and manage” mantra.

What To Expect from Plant Nutrient Sensors

HiRes Vineyard Nutrition Podcast ·

2022/12/12

A goal of the HiRes Vineyard Nutrition Project is to develop tools that make plant nutrient monitoring more efficient. How is this possible? Dr. Jan van Aardt, professor at Rochester Institute Technology (RIT), describes how sensors are being developed and tested in grape vineyards throughout the US.

The Grapevine "Blood Test"

HiRes Vineyard Nutrition Podcast ·

2022/11/28

Each year grape growers collect grapevine samples to send to an analytical lab to determine vine nutrient status. Traditionally petioles are collected, but researchers are encouraging leaf blade sampling. Learn from Dr. Paul Schreiner, Research Plant Physiologist with the USDA-Ag Research Service, the what, when, how and why of tissue sampling for monitoring and managing vineyard nutrition.

Vineyard Nutrition in Arid Climates

HiRes Vineyard Nutrition Podcast ·

2022/11/14

At the helm of the High-Resolution Vineyard Nutrition Project is Director, Dr. Markus Keller, Professor of Viticulture at Washington State University. He describes how he became lead of the project and summarizes the challenges of managing vineyard nutrition in arid eastern Washington wine- and juice-grape vineyards.

How It All Started

HiRes Vineyard Nutrition Podcast ·

2022/10/28

The High-Resolution Vineyard Nutrition Project was borne out of a collaborative effort between grape and wine industry professionals, researchers, and the National Grape Research Alliance (NGRA). Join us to learn about the project from NGRA chair, Dr. Russ Smithyman, and learn how a few dedicated people and good ideas led to this nationally-funded vineyard health project.
