RE: calcium levels--is 3500 ppm too high or just right?
I'm no expert, but I believe you would be better off adding a pure calcium
amendment rather than Gypsum. When I got my soil tests from Neal Kinsey, I
have quantities (and ratio comparisons) of all the major macro & micro
nutrients in the soil. He indicates which additives I need and how much I
need to bring the soil up to snuff. He might be a good source to contact
for what you are looking for. I believe his website/e-mail/contact info has
been posted on the list before. (I don't have it here in front of me or I
would post it again.)
Hope that helps. Good luck this year!

Subject: re: calcium levels--is 3500 ppm too high or just right?
My calcium levels are at 2600 ppm right now (Mg at 300 ppm and
Ca saturation at 72%) and I'm thinking that I should raise Ca a bit,
maybe to 3500 ppm. Does anyone know what levels other really
big pumpkins have been grown in? And the followup question, of
course, is "How much gypsum do I add to a 1000 sq. ft. patch to
raise levels from 2600 ppm to 3500? I already added 40# of
magnesium sulfate and am hoping that will raise my Mg up around
400+ (but I haven't done the math) and that would give me a good
ratio of Ca:Mg, I figure.
Any advice would be appreciated!
