This is another excellent use for that digital scale most of us have kicking around!


Hmmm.... ammonium sulfate.
If my soil pH is high I add peat.
Some people use cider vinegar at 1tbsp/gallon. Cider vinegar I believe is also good for encouraging beneficial soil organisms.
Ammonium is chock-full of Nitrogen and I would not want to get my nutes out of whack.
Not sure what the pH of NH3SO4 is. Hold on while I run down to the chemical closet and make a solution of the stuff. Back to you on that one.

If so how should I go about adding the stuff. I have a bag of it bought from a home and garden shop and it looks like road salt that has been swept up off the streets of Buffalo NY after a long shitty winter.
