Ammonium sulfate has an acidifying effect on soil due to the nitrification process, not from the presence of sulfate, which has a negligible effect on pH. The acid-producing potential of ammonium sulfate is greater than the same N application from ammonium nitrate, for example, since all of the N in ammonium sulfate converts to nitrate,
