Chemical Formula: (NH4)2SO4

Key Characteristics

1. Dual Nutrient Supply:

   • Nitrogen (N) Content: 20.5%~21% (essential for plant growth and chlorophyll synthesis).

   • Sulfur (S) Content: 24%~26% (enhances protein formation and oil synthesis in crops).

2. Physical Form: White or light gray crystalline granules/powder, highly water-soluble, fast-acting.

3. pH Adjustment: Slightly acidic (pH 5-6), ideal for improving alkaline soils.

Primary Applications

• Crops: Rice, wheat, corn, vegetables (as base or top dressing).

• Cash Crops: Tea, tobacco, fruit trees (improves yield and quality).

• Soil Remediation: Reduces pH in alkaline soils and mitigates salinization.
