Notes from the Eastern Viticulture Workshop---Part 4

The last two lectures were given by Dr. Tim Martinson from Cornell University who brought us up to date on the "Northern Grapes Project" and Dr. Paul Domoto from Iowa State University who spoke on "Grapevine Nutrition".
Dr. Tim Martinson provided an update on the Northern Grapes Project.

He also provided information regarding webinars that are held monthly at noon and 7 p.m. The archived webinars can be found here: Recorded Webinars.
Dr. Martinson also mentioned that Viticulture 2013 will be held in Rochster, New York during February 6-8.
Dr. Paul Domoto's talk was on "Grapevine Nutrition". He began his talk with the properties of soil and the importance of soil analysis before planting the vineyard. He recommended that petiole analysis can be taken when the vineyard comes into production. Dr. Domoto gave detailed information on the macronutrients, nitrogen, phosphorus and potassium as well as information on the micronutrients including calcium, magnesium, sulfur, boron, copper, manganese, zinc, and iron. The nutrients also can interact with each other. For example, high magnesium blocks potassium uptake. This information was extensive so members of the audience asked Dr. Nail if the presentation could be circulated. Once I receive the presentation, I will summarize it and put it on this blog.
