Monitoring vine nutrition is critical for pest and water stress resilience and the efficient production of quality grapes. Jenny Garley, Chief Science Officer at NEWAGE Laboratories discusses the differences between SAP analysis and tissue tests. SAP measures real time nutrient availability in vascular tissue. While tissue tests look at the nutrients stored in the leaf; some maybe available but most are not. Learn how SAP analysis can improve your nutrient management program, from reducing nitrogen inputs to managing trace elements for optimal plant nutrition.

[00:02:09] Jenny Garley: Thank you. Actually, thank you for having me back in your team. It's always lovely to speak with you guys and be a part of this. [00:02:19] Craig Macmillan: Yeah, we're glad you could come back. This is really great. I've heard about sap analysis in the past, a long time ago, and didn't really know anything about it because I was a dinosaur and when I was farming, I just did what I'd always done, what people told me to do, basically. That is, monitorin
