Ammonium Sulfate or Sulfate of Ammonia is an inexpensive, readily available form of water-soluble nitrogen. When used in early spring, it encourages rapid leafing out of trees and shrubs and quick greening of lawns. When used on leafy vegetable crops like lettuce and cabbage, it causes more rapid development of these vegetables and promotes quicker harvests. The high percentage of sulfur in this fertilizer makes it especially desirable for acid-loving plants. The high level of nitrogen combined with sulfur in this product means you must be careful how you apply it in hot weather or you may burn the plants and turf. • What the primary nutrients do: Plants need nitrogen to produce and maintain healthy leaves.
