Product Description:
Crystalline Ammonium Sulfate
Crystalline Ammonium Sulfate is a high-quality nitrogen-sulfur fertilizer produced as white or transparent crystals. In addition to supplying essential nitrogen, it is a rich source of sulfur, significantly improving both quality and yield of crops. Its crystalline structure gives it advantages in purity, shelf life, and ease of application compared to other forms of ammonium sulfate.
What is Crystalline Ammonium Sulfate?
Crystalline ammonium sulfate is a mineral salt with the chemical formula (NH₄)₂SO₄, produced as bright white or slightly off-white crystals. Due to its nitrogen and sulfur content, it is widely used in agriculture and various industries. Nitrogen accelerates vegetative growth, while sulfur helps in protein and enzyme formation, enhancing product quality.
Its high water solubility makes it suitable for pressurized irrigation systems, foliar spraying, and direct soil application. According to FAO studies, nitrogenous fertilizers such as ammonium sulfate play a crucial role in improving crop productivity in nutrient-poor soils. Especially in Iran, where alkaline soils are common, this fertilizer reduces soil pH and enhances micronutrient uptake like iron and zinc.
Chemical Composition of Crystalline Ammonium Sulfate
| Component | Details |
|---|---|
| Nitrogen (N) | ~21%, essential for vegetative growth, leaf and branch development, and increased crop yield |
| Sulfur (S) | ~24%, key for protein and enzyme production, improving crop quality and taste |
| Chemical Formula | (NH₄)₂SO₄, a stable and effective compound for nutrient delivery |
| Solubility | Highly soluble in water, ideal for drip irrigation and foliar application |
Physical Properties
| Property | Details |
|---|---|
| Appearance | Bright white or slightly off-white crystals, uniform texture |
| Solubility | Rapid dissolution in water ensures quick nutrient absorption by soil and roots |
| Odor | Odorless, safe and easy to use in various environments |
| Form | Uniform soft crystals, suitable for precise and effective distribution |

| Orchards | Citrus, apple, grape, pistachio; enhances branch growth and fruit quality |
| Vegetables | Tomato, cucumber, onion, potato, cabbage; increases taste and product quality |
| Industrial crops | Sugarcane, cotton, tea; supplies essential nutrients for stable growth |
Recommended Usage
| Crop Type | Dosage | Best Time |
|---|---|---|
| Potted plants | 15 g per plant | Early spring |
| Gardens | 25 g per m² | Before planting |
| Orchards | 1 kg per tree | Early spring |
| Fields | 300–400 kg per hectare | Before planting |
Tip: Irrigate after application to ensure crystals dissolve properly. Avoid overuse to prevent excessive soil acidification.
Application Methods
Furrow application: Place fertilizer in small channels near roots for direct uptake; ideal for wheat and maize.
Fertilizer spreader: Even distribution for large fields like rice and barley.
Manual spreading: For small gardens or plots; careful distribution is needed.
Pit application: Place fertilizer in holes near tree roots for direct nutrition; ideal for citrus and pistachio orchards.
