ammonium sulfate-Ammonium Sulfate As a Lawn Fertilizer
Ammonium sulfate is a water soluble fertilizer providing 21 percent nitrogen by weight and 24 percent sulfur. The guaranteed analysis is 21-0-0+24(S). It can be applied to lawns as a top dressing of nitrogen and sulfur with a broadcast or drop-type spreader. In areas with high pH soils, the sulfur in ammonium sulfate helps lower soil pH levels. As with other fertilizers, water the treated area well after each application.
