Petiole Analysis, 2008 vs 2010

Exactly 2 years ago I took some petioles in (at bloom) to be analyzed by the local plant lab for mineral content.  And right now we're at about 80% bloom. So early this week I sampled from the random patches in the vineyard I did not do a foliar Zinc / Iron addition to find out how our soil amendment plan is doing.  Looks great!

Still need to do those fall Boron supplements (probably more aggressively), and Magnesium came up a bit low, otherwise looking quite good! Note that the units on this chart are in a random assortment of units, a true numbers jock worth her salt would have plotted as % of ideal to normalize the variety of units, ranging from ppm to % of weight. Maybe when she's done with client work she'll make the updates.
