Research results on Plant sap analyses in grapes

The past months our consultant Eric Hegger has been diving in to the different elemental interactions in grape, based on the data we have collected over the years in combination with on-site research.

In the video down below he will present the results of this research. The subjects discussed in this presentation:
      -   Nutrient influences on the sugar levels in plant sap.
      -   Nutrient influences on the pH in plant sap.
      -   Antagonistic interactions between nutrients.
      -   Deficiency levels in grapes.
