had to dig this thread up to remind myself of the ratio, i lost one of my soil recipe notebooks in a recent move....
im adding azomite into the mix at less than .5 part, simply because i have it around
fyi the updated mineral mix is
per 1 cubic foot base mix add:
1 cup oyster shell powder
1 cup gypsum
1 cup basalt rock dust
1 cup glacial rock dust
azomite should make a good 1:1 replacement for the glacial rock dust.

Rock dusts are mostly neutral, no?
Have you used this mix at that rate?
At least we aren't trying to lime with crab shell. Those poor fools on GC.
something pH neutral would raise the pH of something acidic.. or am I wrong?

In my opinion its the calcium that raises the ph.
Being crab shell is 24% calcium of course it will have a liming affect.

When I see ph. neutral I think it does nothing to influence the ph. of whatever mix.
i've used that mix or a mix very much like it, using NO dolomite lime and only gypsum, oystershell meal, azomite, basalt, and local sand as minerals/ liming agents.
haven't had problems,
only problem is remembering the specifics when it's time to mix more.
