Dixondale Farms’ Ammonium Sulfate 12 lb. Bag


  • Feed Your Onions with a High Source of Nitrogen

Share Product:


Ammonium Sulfate 21-0-0 provides a high source of nitrogen which is what onions need to generate more foliage and therefore more rings and larger bulbs.

Directions: Apply first application 3 weeks after planting, then continue every 2-3 weeks. Sprinkle 1 cup per 20 feet of row. This product readily dissolves in water and can me mixed with 1 cup in a gallon of water to treat one bunch. Apply when tops of onions are dry. Once the neck starts feeling soft do not apply any more fertilizer (approximately 4 weeks prior to harvest). Always water immediately after feeding and maintain moisture during the growing season. Onions need more water closer to harvest.

12 lb. bag will treat 560 ft. of row.
