In this episode, we have a conversation with Dr. Markus Keller of Washington State University on the advances in vineyard nutrition monitoring. Dr. Keller shares his extensive knowledge of the importance of nutrient management in viticulture, drawing from his rich background and current research. We discuss strategies for regulated deficit nutrition management, winter survival tactics, emerging technologies like remote sensing for precision nutrient management, and much more.

Listen in and soak up the information that Dr. Keller shares with us about all things vineyard nutrition monitoring.

In this episode, you will hear:
