I wanted to pass along some late season resources that may be helpful to many of ya’ll. Many of us are still in the middle of harvest right now. Hopefully our grape producers in South GA are mostly done and will be safe with the oncoming Idalia!
Just a reminder that if you are seeing signs of overly stressed vines (too much yellow or red leaves too soon), be sure to at least flag that vine for later assessment when you have more time!

- The HiRes Vineyard Nutrition podcast, hosted by Oregon State’s viticulturist, Dr. Patty Skinkis, was created to document some of the very cool research looking at better ways to monitor and manage vineyard nutrition through precision ag. A recent episode is talking about nitrogen in wine through a discussion with Dr. Amanda Stewart, Assoc. Professor of Food Science and Technology at Virginia Tech. Podcast episodes and full written transcripts are available at http://beav.es/5GD (and Spotify).
