21-0-0 Ammonium Sulfate Lawn Fertilizer

21-0-0 Ammonium Sulfate Lawn Fertilizer 

21-0-0 Ammonium Sulfate delivers 21% nitrogen and 24% sulfur in a free-flowing granular form designed for sulfur-deficient and alkaline soils. This non-leaching formula is particularly effective for rice, wheat, and pastures while serving as an excellent choice for lawns, gardens, and ornamental plantings where phosphorus and potassium levels are already adequate. The ammoniacal nitrogen source resists leaching, promoting sustained nutrient availability. Apply directly or blend with other fertilizers for customized nutrient programs across turf, vegetables, flowers, shrubs, and trees.
