Here's an abridgement of what the article does say, in case anyone besides
Jim is interested in our little discussion.
"It is best to prepare the ground a year or more in advance of planting your
blueberries. Why? You mentioned jusing sulfur to acidify your ground and
it takes a long time to do its task....
Q. As I've stated on this site before, I have seen very healthy and
productive blueberries growing in soils with a pH in the mid 6's and others
corroberated this observation- Alan Haigh.
A. Alan, I seem to remember that mentioned, where growers have bound up the
soil calcium and added additional magnesium but I don't recall anyone saying
what they did to de-activate the calcium. If I had a corner of land that I
didn't care what happened to, I'd try that. If you were to apply enough
phosphoric acid to bind the calcium, turning into the insoluble form,
calcium phosphate, you should be able to acidify the soil a lot faster than
by acidifying with sulfur..."
This is part of what Jim posted last here , "Alan, I didn't say that!
I just got a copy of my Pomona article and compared it to your post,
below. I think you need to re-read my article and then re-read your
comments. I DIDN'T SAY THOSE THINGS! And where did you get the statements
about iron? I didn't even mention iron! Could you be confusing my article
with someone else's?"
Jim, Iron is the whole issue of what is damaging about higher pH soils for
acid lovers. It makes adequate iron unavailable. I assumed you were
speaking from this understanding. I have reread your article and stand by
everything I've written, although it's all no big deal- I just don't think
anyone should wait a year to grow their dam blueberries. People can follow
any advice they want. You clearly state that it is necessary to incorporate
adequate sulfur ahead of time and suggest waiting a year to make sure that
this is accomplished. I disaggree.
