For decades, growers have used leaf tissue analysis to monitor nutrient uptake. The problem with this technique is that when we study leaf tissue samples, we are looking at the past.

This presentation will explore how extracting and analyzing plant sap can help growers make real-time decisions that lower their production costs and improve crop quality.
