Ammonium sulfate is available in various forms and products to cater to different applications. Some common types of ammonium sulfate products include:

1. Granular Ammonium Sulfate: This is the most common form of solid ammonium sulfate fertilizer. It consists of granules that are easily spread and applied to agricultural fields. Granular ammonium sulfate provides a controlled release of nitrogen and sulfur, supporting plant growth and improving soil fertility.

2. Powdered Ammonium Sulfate: Powdered ammonium sulfate is a finely ground form of the compound. It is used in various industrial applications, including chemical synthesis, protein precipitation, and as a component in the manufacturing of other products.

3. Crystal Ammonium Sulfate: Crystal ammonium sulfate refers to the compound in its crystalline form. It is often used in laboratory settings for protein purification and other analytical procedures. The crystals can be dissolved in water or other solvents for specific applications.

4. Liquid Ammonium Sulfate: Ammonium sulfate can also be found in liquid form. It is typically used in specialized applications, such as foliar spraying in agriculture or as a component in liquid fertilizers. Liquid ammonium sulfate offers ease of application and can be more convenient in certain situations.

5. Ammonium Sulfate Blends: Ammonium sulfate may be blended with other fertilizers or additives to create customized formulations. These blends can provide a combination of nutrients and desired properties based on specific crop requirements or soil conditions.
