Ammonium Sulfate (NH4)2SO4 - Product Introduction

Beyond core agricultural use, it is also a versatile industrial raw material, applied in feed additive production, water treatment, metal plating, and pharmaceutical pH regulation. With the advantages of fast nutrient release, easy crop absorption, wide adaptability, low cost and simple storage, it has become an indispensable product for both agricultural fertilization and industrial manufacturing.

Core Product Advantages

1. Dual Nutrient Supply: Integrates 21% ammonium N and 24% water-soluble S, one fertilizer meets two core nutrient demands of crops, improving fertilization efficiency.
2. Fast & Effective Fertilization: High water solubility ensures rapid nutrient release; ammonium nitrogen is directly absorbable by crop roots, with obvious fertilizer effect in 3-5 days after application.
3. Chlorine-Free & Wide Adaptability: Chlorine-free formula, safe for chlorine-sensitive crops (tobacco, tea, potato); weakly acidic, ideal for alkaline/calcareous soils and adaptable to most soil types.
4. Diversified Application Forms: Powder for foliar spraying/drip irrigation, granular for manual spreading, spherical granular for mechanical large-area sowing—matches all agricultural operation modes.
5. Stable & Easy to Handle: Non-toxic, non-flammable, chemically stable at room temperature; low moisture absorption, easy to store and transport with long shelf life.

6. Cost-Effective: High nutrient content, simple production process, low unit cost, suitable for both small household planting and large-scale commercial agricultural production.

Main Applications

1. Agricultural Field (Primary Application)

• Suitable Crops: Universal for grain crops (rice, wheat, corn), cash crops (cotton, rapeseed, tobacco), fruits & vegetables (apple, citrus, tomato, cucumber); especially effective for sulfur-loving crops (garlic, onion, cabbage).
• Application Methods: Usable as base fertilizer, top dressing and foliar fertilizer; applicable for drip/sprinkler irrigation (water-fertilizer integration) and compound fertilizer blending.
• Core Effects: Promotes chlorophyll and protein synthesis, prevents N/S deficiency yellowing, improves crop yield and quality; moderately optimizes alkaline soil structure, enhances soil fertility.

2. Industrial & Other Fields (Secondary Application)

• Feed Additive: Food-grade ammonium sulfate supplements N and S for livestock/poultry, promotes animal protein synthesis and growth development.
• Water Treatment: Serves as a flocculant adjuvant for industrial wastewater treatment, improving sedimentation and purification efficiency.
• Industrial Raw Material: Used in metal plating electrolyte, pharmaceutical pH regulator, paper fire retardant and chemical synthesis raw material.

• Compound Fertilizer Production: As a nitrogen/sulfur source for blending compound and mixed fertilizers, enriching nutrient components of compound fertilizers.
