Ammonium sulphate is widely used as a sulphur (S) fertilizer, constituting about 50% of global S use. Within nitrogen (N) management, it is well known that ammonium-based fertilizers are subject to ammonia (NH3) volatilization in soils with pH > 7, but this has been overlooked in decision making on S fertilization.
Ammonium sulfate is a white crystalline salt with the chemical formula (NH4)2SO4, commonly used in agriculture as a nitrogen-rich fertilizer. Its high nitrogen content makes it an excellent source of plant nutrients, promoting healthy growth and improved crop yields. It is also utilized in industrial applications such as food processing, water treatment, and flame retardant production. Ammonium sulfate can be applied directly to soil or mixed with other fertilizers, making it a versatile and valuable resource for enhancing plant nutrition and soil quality in agriculture.

Ammonium sulfate is a common inorganic salt. It contains two ammonium ions and one sulfate ion. This salt is widely used in various applications, including agriculture, industrial processes, and laboratory settings. Here are some key points about ammonium sulfate: Nitrogen and Sulfur Content: Ammonium sulfate is a good source of both nitrogen and sulfur. The nitrogen is in the ammonium form, making it readily available for plants. Solubility: Ammonium sulfate is highly soluble in water, allowing it to be easily dissolved for use in liquid fertilizers or irrigation systems. Fertilizer Use: It is commonly used as a nitrogen and sulfur fertilizer in agriculture to provide essential nutrients for plant growth. The nitrogen in ammonium sulfate is gradually released, providing a sustained nutrient supply to plants. Acidity: Ammonium sulfate is acidic in nature, and its application can contribute to lowering the pH of the soil. This can be beneficial in alkaline soils or for crops that prefer slightly acidic conditions. Soil Amendment: In addition to providing nutrients, ammonium sulfate can also serve as a soil amendment for improving certain soil characteristics. Industrial Applications: Ammonium sulfate is used in various industrial processes, including the production of textiles, dyes, and flame retardants. It is also employed in certain chemical reactions and as a precipitant in laboratories. Yeast Nutrient: In the brewing industry, ammonium sulfate is sometimes used as a yeast nutrient in the fermentation process. Compatibility: Ammonium sulfate is generally compatible with other fertilizers, and it can be used in combination with them to provide a balanced nutrient profile. Safety Considerations: When handling ammonium sulfate, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation. Storage: Ammonium sulfate should be stored in a cool, dry place to prevent moisture absorption.
1. Used as a paper sizing agent in the papermaking industry to enhance the water resistance and impermeability of paper; 2. After being dissolved in water, it can cause small particles and natural colloidal particles in the water to condense into large flocs, which can be removed from the water. Therefore, it is used as a coagulant for water supply and wastewater; 3. Used as a turbid water purifier, as well as a precipitator, color fixative, filler, etc. Used as a raw material (astringent) for anti sweat cosmetics in cosmetics; 4. In the fire protection industry, foam extinguishing agent is composed of baking soda and foaming agent; 5. Analytical reagent, mordant, tanning agent, oil decolorizing agent, wood preservative; 6. Stabilizers for albumin pasteurization (including liquid or frozen whole eggs, protein or egg yolk); 7. It can be used as raw material to produce artificial gemstones, high-grade ammonium alum and other aluminate; 8. In the fuel industry, it serves as a precipitator in the production of chrome yellow and lake dyes, while also serving as afixing and filling agent.
Surfactant Ammonium Laureth Sulfate CAS 32612-48-9 ALES 70% Lauryl glycol polyether has antifoam properties. Polyether defoamer is a major variety of defoamer at present, which has the advantages of non-toxic, tasteless, non-irritating, resistant to hard water and acid and alkali, and good compatibility with the system. Compared with another class of silicon-containing defoamer, although its defoamer performance is not high, its anti-foam performance is quite excellent.
