Ammonium sulfate [(NH4)2 SO4] was one of the first and most widely used nitrogen (N) fertilizers for crop production. It’s now less common but especially valuable where both N and sulfur (S) are required. Its high solubility provides versatility for a number of agricultural applications.
Ammonium sulfate fertilizer from Sanyuanjiuqi is a highly effective and versatile fertilizer product that plays a crucial role in promoting healthy plant growth. It is a granular fertilizer that contains essential nutrients, namely nitrogen and sulfur, in a balanced form. The high nitrogen content in ammonium sulfate provides plants with the necessary fuel to develop robust foliage, promote vegetative growth, and enhance overall productivity.
• Highly Effective Formula: Ammonium sulfate fertilizer is a carefully balanced blend of nitrogen and sulfur, providing your plants with precisely what they need for optimal health and development.
• Nitrogen-Rich Fuel: Boasting a remarkable 20.5 percent nitrogen content, ammonium sulfate granular turbocharges your plants with the energy they crave, resulting in lush, green foliage that's the envy of any gardener.
• Versatile Applications: Ammonium sulphate water soluble fertilizer isn't just limited to one use; it's a versatile ally for various scenarios in agriculture.
• Optimal Growth: With ammonium sulfate, you're not just feeding your plants; you're nourishing their potential. Experience the extraordinary growth that leads to bountiful harvests.
• Sulfur Support: While other fertilizers may offer concentrated nitrogen, ammonium sulphate for plants stands out as an exceptional source of sulfur. This vital element powers essential plant functions, including protein synthesis, for enhanced vitality.
Ammonium sulfate (sometimes abbreviated as AS or AMS) has been produced for more than 150 years. Initially, it was made from ammonia released during manufacturing coal gas (used to illuminate cities) or from coal coke used to produce steel. Today, manufacturers make it by reacting sulfuric acid with heated ammonia. To get the crystal size best suited for the application, they control the reaction conditions by screening and drying the particles until achieving the desired size. Some materials are coated with a conditioner to reduce dust and caking.
Byproducts from various industries meet most of the current demand for ammonium sulfate. For example, the nylon manufacturing process produces ammonium sulfate as a co-product. In another, certain byproducts that contain ammonia or spent sulfuric acid are commonly converted to ammonium sulfate for use in agriculture.
Although the color can range from white to beige, ammonium sulfate is consistently sold as a highly soluble crystal with excellent storage properties. As described earlier, particle size can also vary depending on the intended purpose.
Growers apply ammonium sulfate primarily where they need supplemental N and S to meet the nutritional requirement of growing plants. Since ammonium sulfate contains only 20.5 percent N, other fertilizer sources more concentrated and economical to handle and transport often make a better choice for N-deficient fields. However, it provides an excellent source of S, which supports or drives numerous essential plant functions, including protein synthesis.
Because the N fraction is present in the ammonium form of ammonium sulfate, rice farmers frequently apply it to flooded soils, since nitrate-based fertilizers are a poor choice due to denitrification losses.
A solution containing dissolved ammonium sulfate is often added to post-emergence herbicide sprays to improve their effectiveness at weed control. This practice of increasing herbicide efficacy with ammonium sulfate works particularly well when the water supply contains significant concentrations of calcium (Ca), magnesium (Mg) or sodium (Na). A high-purity grade of ammonium sulfate often works best for this purpose to avoid plugging spray nozzles. Welcome to contact us for the latest ammonium sulphate fertilizer price!

1. Supplemental N and S: When your plants hunger for nitrogen and sulfur, reach for ammonium sulfate. It's the go-to choice to meet their nutritional needs, ensuring they flourish in any environment.
2. Flooded Soil Resilience: Especially favored by rice farmers, ammonium sulphate fertiliser excels in flooded soils. Its ammonium-based composition makes it the ideal choice, preventing denitrification losses.
3. Enhanced Herbicide Efficacy: Take control of weed management by incorporating dissolved ammonium sulfate into your herbicide sprays. It elevates their effectiveness, especially when water sources contain calcium, magnesium, or sodium. For optimal results, choose a high-purity grade to avoid spray nozzle clogs.
Use Suggestions:
General Use: Spray 4 to 7 kg per acre as a foliar application to supplement nutrients available from fertilizers applied to soil.
Aerial Application: Can be mixed at rate of 120kg/m3 of water per acre.
Backpack Sprayer: 1/3 TBSP per liter.
Mixing: Add to mix or spray tank when it is about half full then continue to fill.
Caution: Do not apply to drought stressed plants or during hot, high light conditions or when plants are wilting. Do not use with highly alkaline sprays, dormant oils, dinitro compounds, or lime-sulfur mixtures.
It can be mixed with most kind of fertilizeres and most besticides and fungicides except oils or any products containing calcium or which are high in alkaline.
It should be stored out of direct sunlight and preferably in a dry and cool place under frost – free condition
