Ammonium Sulfate Crystal 21% N - Nitrogen Fertilizer, Fire Retardant, Yeast Nutrient
Ammonium sulfate (chemical formula (NH₄)₂SO₄) is a vital ammonium nitrogen fertilizer and industrial salt. This product appears as white or slightly yellowish crystalline granules or powder, featuring a salty and bitter taste with no odor. Its primary value lies in delivering plant-available ammonium nitrogen (N) and sulfur (S) nutrition. With stable chemical properties, moderate solubility, and consistent nitrogen content (approximately 21%), it maintains extensive applications across agriculture, industry, bioprocessing, and fire protection sectors.
Core Applications
Agricultural Production - Nitrogen-Sulfur Fertilizer
Quick-Acting Nitrogen Fertilizer: One of the original nitrogen fertilizers with nitrogen in ammonium ions (NH₄⁺) form for direct root absorption and rapid effectiveness
Ideal for top-dressing applications across various soils and crops
Particularly beneficial for sulfur-loving crops (onions, garlic, rapeseed, tobacco) and chloride-sensitive crops (tobacco, potatoes, citrus)
Note: Long-term heavy application may cause soil acidification, requiring lime or organic fertilizer combination
Industrial and Chemical Applications
Flame Retardant Raw Material: Fundamental component for manufacturing intumescent flame retardants; decomposes to produce ammonia and non-combustible gases for wood, paper, and textile treatments
Yeast Cultivation and Fermentation: Essential nitrogen and sulfur source nutrient for microbial fermentation in beer brewing, yeast production, and antibiotic fermentation
Rare Earth Metallurgy and Ore Flotation: Functions as precipitating agent in rare earth separation and as depressant/activator in mineral flotation
Battery Electrolyte: Component in certain lead-acid battery electrolytes
Specialized Applications
Food Additive: Food-grade variant serves as processing aid, dough conditioner, and yeast nutrient in baked goods (compliant with GB 29206 standards)
Biopurification: Used for salting-out precipitation in protein purification processes
Firefighting Agent: Component in select dry powder fire extinguishing formulations
Purity specifications, heavy metal impurity limits, whiteness requirements
Food Grade
High purity meeting GB 29206 standards for food processing applications
Reagent Grade
Ultra-high purity for laboratory and research applications
Usage and Storage Guidelines
Agricultural Application
Optimal as top-dressing fertilizer with deep soil application and coverage to minimize ammonia volatilization. Avoid mixing with alkaline fertilizers (plant ash, lime) to prevent ammonia gas release.
Storage Requirements
Store in cool, dry conditions with sealed packaging to prevent caking and moisture absorption.
Safety Considerations
Dust may irritate respiratory tract; implement appropriate protective measures during handling operations.
Our ammonium sulfate products deliver consistent nitrogen content, uniform granulation, excellent solubility, and minimal impurities. We supply bulk, stable, high-quality material to fertilizer distributors, compound fertilizer manufacturers, flame retardant producers, fermentation plants, chemical facilities, and research institutions. For crop nutrition programs, flame retardant formulations, or fermentation optimization, we provide expert product selection guidance and technical application support.
