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.

How far have we come in developing sensors for monitoring vineyard nutrition? In this episode, Dr. Alireza Pourreza, Associate Professor of UC Cooperative Extension, talks about his lab's research into nitrogen sensor development and the robust models they feed into that will be useful for farm decision-making. Podcast transcript and details are available at http://beav.es/5GD.

In this episode, we break the status quo and discuss alternative grapevine tissues being investigated for nutrient sampling. Dr. Nataliya Shcherbatyuk, post-doctoral researcher at Washington State University and the HiRes Team’s Project Manager, describes the research she conducted to understand the validity of other tissues in correlating with standard methods and how that project led to interesting findings about nutrient losses due to frosts and wind.

Getting a representative tissue sample from the vineyard can be challenging without some prior information or knowledge of the vineyard property. In this episode, Manushi Trivedi, Cornell University PhD student, talks about the work they are doing to pin-point where to sample in as few locations as possible to best represent vineyard blocks in nutrient sampling. Podcast transcript is available at http://beav.es/5GD.

How are sensors developed for nutrient status detection? In this episode, Dr. Chenchen Kang, former Washington State University graduate student, describes how hyperspectral sensors are being developed to scan grapevine canopies to detect nitrogen status. Learn about the current successes in the research process and future endeavors. Podcast transcript is available at http://beav.es/5GD.

Did you ever wonder how much nitrogen grapevines takes up and when? In this episode, Tom Groenveld, former HiRes Vineayrd Nutrition project manager and post-doctoral scholar at Washington State University, describes a hydroponic nitrogen feeding study he conducted with Cabernet Sauvignon grapevines to address this question. Podcast transcript is available at http://beav.es/5GD.

What is the economic value of making good farm management decisions? In this episode, Alejandro Abarca, Graduate Research Assistant and PhD candidate at Oregon State University, describes research conducted to quantify economic value of vine nutrient management using grapevine tissue nutrition data and end-of-season yields to develop a model to help predict yield impacts in the future. Transcript is available at http://beav.es/5GD.

In this episode the microphone is flipped on our host, Dr. Patty Skinkis, HiRes Vineyard Nutrition Project Co-Director, who speaks about her path to viticulture research, Extension, and this project. She also speaks to the importance of sharing research results and developing communications streams to inform and build research that impacts industry.

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.

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.
