Ammonium Sulfate Fertilizer 21-0-0 with 24% Sulfur

Greenway Biotech Ammonium Sulfate Fertilizer 21-0-0 supplies 21% nitrogen as ammonium and 24% sulfur in a water-soluble form. Use it where your lawn or crop needs these nutrients, including suitable blueberry and acid-loving plant programs.

Nitrogen supports leafy growth, while sulfur contributes to amino acids and proteins. Ammonium sulfate can also acidify soil over time. Choose the application rate from your crop’s nitrogen needs and soil conditions, and monitor pH with repeated use.

For example, a lawn nitrogen target of 0.5 lb N per 1,000 sq ft requires approximately 2.38 lb of product. Apply evenly, keep granules off foliage and pavement, and water in. See the application guide and calculator for rates, limitations, and bag recommendations.
