ammonium sulfate

I want to put on ammonium sulfate and then pre. later on. In Nebraska with clay lawns with a high PH, I thought adding A.S. first to break up the binding of the PH and then put down pre with a slow release fertalizer. How much time should I leave in between the apps. since A.S. is a fast release fert? My biggest problem is controlling foxtail and some crabgrass.

Applying AMS won't do much to relieve a high ph and clay soil on the short term. There are much better ways to get that done than with AMS. Getting your pre down is the first thing you should do, if the turf needs fert then maybe a combo product with AMS in it would be the ticket. Sulfur and aeration will be the best way to get the ph in line, and loosen the clay.
