Re: ammonian sulfate

David,

         Ammonium sulphate has 20% nitrogen, but it is slow release.  It
also has 24% sulphate which acidifies the soil, and so it helps with
alkaline situations.  It's used a lot agriculturally, but I'm not familiar
with it for lawn use.

Found this at the U. of Illinois website:

"Yes, you can use ammonium sulfate in either the lawn or garden. It is an
excellent source of nitrogen and if needed it is also a source of sulfur.
The material can be broadcast in the granular form on the surface of the
soil without concern for incorporation as it is non-volatile. Ammonium
sulfate contains approximately 21 percent nitrogen. Use that percentage
when deciding how much to apply to your lawn or garden. Normally, one
applies 3/4 to 1 lb N per thousand square feet of lawn."
