Product Description:
Powdered Ammonium Sulfate
Powdered Ammonium Sulfate is one of the most widely used and oldest nitrogen-based chemical fertilizers in the world. Due to containing two essential elements, Nitrogen (N) and Sulfur (S), it plays a significant role in the growth and development of plants. This fertilizer is produced in the form of a white or light-gray powder. Because of its high solubility in water and rapid absorption in soil, it is used for various field crops and orchards.
What is Powdered Ammonium Sulfate?
Powdered Ammonium Sulfate (Ammonium Sulfate Powder) is an inorganic salt with the chemical formula (NH₄)₂SO₄, offered as off-white crystals or fine powder. Owing to its high water solubility and its ability to provide both Nitrogen and Sulfur simultaneously, it has gained a prominent place in many industries.
Nitrogen in this fertilizer improves vegetative growth, greenness, and crop yield.
Sulfur contributes to protein and enzyme formation, enhancing final product quality.
First industrially produced in Europe, today Iran is also considered one of its key producers in the region. With advanced equipment and high-quality raw materials, the product is manufactured with excellent purity, suitable for both domestic and export markets.
Unlike the granular type, this fine and light powder dissolves quickly in water, making it ideal for drip irrigation systems, foliar spraying, or even manual broadcasting. According to the FAO, nitrogen fertilizers like ammonium sulfate are vital for boosting yields in nutrient-poor soils.
This is especially important in alkaline soils (common in Iran), as this fertilizer reduces soil pH, allowing nutrients such as iron and zinc to become more available to plants.
Whether you are growing a few tomato plants in your backyard or managing hectares of wheat, powdered ammonium sulfate can make a significant difference.

Agricultural Applications
Powdered Ammonium Sulfate, containing 21% Nitrogen (N) and 24% Sulfur (S), is one of the best chemical fertilizers for enhancing crop growth and improving product quality. With its high solubility in water and fast absorption in soil, it is widely used for different types of cultivation. This fertilizer is especially effective in the alkaline soils of Iran, where it helps reduce soil pH and improves nutrient availability.
Below is a comprehensive overview of its agricultural applications, recommended usage instructions, and practical benefits:
Field Crops
Ideal for wheat, barley, rice, corn, canola, and legumes.
Nitrogen boosts vegetative growth, while sulfur enhances grain quality.
For example, the use of ammonium sulfate in wheat fields can significantly increase grain yield.
Orchards
Highly recommended for citrus, apple, grape, and pistachio trees.
Provides essential nutrients for stronger branch growth and higher-quality fruits.
Particularly effective in pistachio orchards in Iran, where alkaline soils require pH reduction.
Vegetables & Greenhouse Crops
Perfect for tomato, cucumber, onion, potato, and cabbage cultivation.
Nitrogen accelerates leaf and stem development, while sulfur improves taste, aroma, and overall crop quality.
Industrial Crops
Suitable for sugarcane, cotton, and tea.
Due to its high solubility and balanced nutrient composition, it ensures continuous feeding and better crop performance.
Recommended Application Rates of Powdered Ammonium Sulfate in Different Crops
| Crop | Recommended Dosage | Practical Effects |
|---|---|---|
| Wheat & Barley | 150–200 kg/ha | Increases yield and improves gluten quality |
| Rice | 100–150 kg/ha | Enhances tillering and cooking quality |
| Fruit Orchards | 2–3 kg per tree | Improves fruit color and taste |
| Vegetables | 50–70 kg/ha | Boosts growth and prolongs shelf-life |
| Maize (Corn) | 120–180 kg/ha | Increases kernel number per cob |
| Sugarcane | 200–300 kg/ha | Enhances stalk growth and sugar content |
| Potato | 100–150 kg/ha | Improves starch accumulation and cooking quality |
Application Guidelines
For best results, the dosage of powdered ammonium sulfate should be adjusted according to crop type and soil requirements. Suggested application rates are listed below:
| Cultivation Type | Dosage | Best Timing |
|---|---|---|
| Pots | 15 g per plant | Early spring |
| Gardens | 25 g per m² | Before planting |
| Orchards | 1 kg per tree | Early spring |
| Farmlands | 300–400 kg/ha | Before planting |
Important Note: Always irrigate after applying fertilizer to ensure proper dissolution and absorption into the roots. Avoid overuse to prevent excessive soil acidification.
Suggested Methods of Application
Furrow Application (Banding): Fertilizer is placed in small channels beside crop rows to maximize nutrient uptake (effective for wheat, maize, canola).
Broadcasting (Spreader): Suitable for large-scale crops such as rice or barley; ensures even distribution.
Hand Spreading: Useful for small gardens, though requires care for uniform coverage.
Pit Application (Deep Placement): Best for fruit orchards (citrus, grapes, pistachios); fertilizer is applied into small pits near roots.
