First off Miracid is a fertilizer not a soil ammendment.

Almost all chemical fertilizers will be acid and the ones for crops
will tell you how much lime per ton of fertilizer you need to apply to
counteract the acidity.

To keep your soil acid your best bet would be to work a little sulfur
into the top inch or so and to keep the lawn lime away from your
plantings.
For faster results you would use aluminum sulfate.

To provide sulfur and nitrogen you could use a fertilizer whose
nitrogen componant came from ammonium sulfate.

As for the calcium concerns in the original post you either learn to
recognize deficiency or you do a soil test.

hi
thank you for replying...
i *do* use mirAcid on some (azaleas) and tested the soil which in all
except for 1 (which i had given sulfur to for ?mites/root problems)) were
neutral to basic (on the test capsules and a pool testing kit)
with the pool kit however, the pH was 6.8 for the sulfurized one...
i don't know how to test for calcium...
thanks again
sincerely
