A dual-nutrient fertilizer providing Nitrogen and Sulphur in a highly soluble form. Ideal for lowering the pH of alkaline soils common in the UAE and ensuring vigorous crop growth. Available in Granular (2–4mm) and Crystalline forms.
Product Description
Ammonium Sulphate (Granular/Crystal)
Product Overview
Ammonium Sulphate Fertilizer is one of the most reliable nitrogen fertilizers available for arid and alkaline soil conditions. Unlike urea, it provides nitrogen in the ammonium form ($NH_4^+$), which resists leaching and binds well to the soil.
But the real advantage for farmers in the Gulf region is the sulphur content. With 24% Sulphur, this product doesn’t just feed the plant; it actively improves the soil environment. The sulphate lowers the pH of the root zone, helping plants absorb micronutrients like iron and manganese that often get “locked up” in high-pH sandy soils.
We supply high-purity Ammonium Sulphate suitable for direct application, bulk blending, or fertigation.
Key Benefits-Ammonium Sulphate Fertilizer
Dual Nutrition: Delivers 21% Nitrogen for leafy growth and 24% Sulphur for protein synthesis and enzyme function.
Soil Acidification: The ammonium releases acidity as it converts to nitrate, helping neutralize high soil alkalinity.
Less Nitrogen Loss: Significantly lower volatilization (gas loss) compared to urea when applied to the surface.
Versatile Application: Soluble enough for spray systems and durable enough for mechanical spreading.

Applications
Agriculture
This is the primary choice for alkaline soils. It is widely used for:
Field Crops: Wheat, corn, and barley.
High-Value Crops: Potatoes, onions, and citrus fruits (which crave sulphur).
Drip Irrigation: The crystalline grade dissolves rapidly without clogging emitters.
Industrial Uses
Beyond farming, our Ammonium Sulphate serves several industrial sectors:
Water Treatment: Used as a flocculant disinfectant aid.
Flame Retardants: A key ingredient in fire extinguisher powders.
Textiles: used in acid dyes for better color fixation.
Handling and Storage-Ammonium Sulphate Fertilizer
Store in a cool, dry, well-ventilated area.
Keep bags sealed to prevent moisture absorption (caking).
Incompatible with strong alkaline substances (like lime) as this causes ammonia loss.
Frequently Asked Questions (FAQ)
Why choose Ammonium Sulphate over Urea?
While Urea has more nitrogen (46%), it lacks sulphur. Ammonium Sulphate provides both. More importantly, it is less likely to gas off into the air in hot weather, making it more efficient per kilogram of applied nitrogen in many scenarios.
Is this product suitable for hydroponics?
Yes, the crystalline grade is highly soluble and clean, making it suitable for hydroponic solutions where ammonium nitrogen is required.
How does it help with UAE soil?
UAE soil is typically sandy and alkaline (high pH). High pH prevents plants from eating the food in the soil. Ammonium Sulphate lowers that pH locally around the roots, effectively unlocking nutrients for the plant.
