NW Washington | Ammonium Sulphate is 21 percent N and 24 percent Sulphate, so if you need sulphur it might be a good choice. However, the low percentage of N means you have to apply a lot of material to get very much nitrogen on your soil.
Ammonium Nitrate is 34 percent N but it is also used as an explosive by bad guys so dealers have to be a little cautious which probably adds to the price. Urea, the other dry N fertilizer is 46 percent N.
