Product Features
1. Dual supplement of nitrogen and sulfur
Stable nitrogen content while supplementing sulfur, promoting crop protein synthesis, improving yield and quality, and relieving nitrogen and sulfur deficiency symptoms.
2. Soil improvement
Acidic formula helps adjust pH of alkaline soil, improve soil compaction, activate soil microorganisms, and enhance soil fertility.
3. Fast-acting and easy to absorb
Good water solubility, dissolves quickly after application. Nitrogen can be directly absorbed by crops, ensuring fast fertilization effect and high utilization rate.
4. Excellent physical properties
Uniform and round particles with moderate hardness. Not easy to agglomerate, convenient for storage, transportation, and mechanical spreading.
5. Safe and compatible
Can be mixed with phosphorus, potassium fertilizers, and organic fertilizers without antagonism. No residue after long-term use and mild to crop roots.
Application Scenarios
Agricultural field use
Ammonium Sulfate ((NH₄)₂SO₄) Suitable for alkaline and neutral soils. Used for wheat, corn, rice, cotton, fruits, and vegetables such as apples, pears, citrus, and leafy vegetables. Can be used as base fertilizer (deep application with organic fertilizer), topdressing (spreading or fertigation), and seed fertilizer (small amount applied during sowing).
Special crop advantages
Particularly suitable for sulfur-deficient soils, improving disease and pest resistance and enhancing crop quality. Also suitable for chlorine-sensitive crops such as tobacco and tea, replacing chlorine-containing fertilizers to avoid chlorine damage.
Industrial applications
Used in chemical, textile, electroplating, and pharmaceutical industries.
