Ammonium Sulfate Fertilizer (AS 21%)
What is Ammonium Sulfate AS %21 (Sugar Fertilizer)?
Ammonium sulfate fertilizer is a chemical fertilizer known for its high nitrogen (N) content of 21% and sulfur (S) content of 24% in sulfate form. This white, crystalline or granular fertilizer is commonly referred to as "sugar fertilizer." It meets the sulfur requirements of plants, making it suitable for both top-dressing and base fertilization. The ammonium form of nitrogen enhances the uptake of phosphorus in the soil.
Benefits of Ammonium Sulfate AS %21
- Nutrient Provision: Provides essential nitrogen and sulfur nutrients crucial for plant growth and development.
- Soil Efficiency: Enhances phosphorus uptake in the soil, thereby increasing crop yield.
- Versatile Use: Ideal for tea, rice, cereals, fruits, and vegetables.
- Soil Acidity: Prolonged use may increase soil acidity, necessitating liming.
