Why are they recommending more phosphorus if its borderline very high? I think having a tissue and soil test to look at side by side would be helpful.

I don't know why they would recommend more phosphorus at my soil levels. I honestly don't really look at their recommendations, I have an agronomy background and usually figure it out on my own for my field crops and have just kinda done the same with these things. I haven't done any tissue testing, I struggle with interpretation, do we really know what tissue levels we need to see in these giants? Also tissue levels can be raised with foliar applications but do those nutrients actually make it to the fruit? I have more questions than answers on these things.
My plan has to take sequential soil samples and try to optimize soil as much as possible. I don't think I'm far from where I want to be other than K and B being a little lower than I would like.

The other thing that bothers about this test result me is copper and phosphorus dropping drastically on this test compared to the last, neither should be going anywhere, they are both very stable in the soil. I'm going to send another sample off tomorrow.
