Product Description:
Granular Ammonium Sulfate (Granular Ammonium Sulfate)
Granular ammonium sulfate is one of the most widely used nitrogen-sulfur fertilizers, produced in uniform granules. Due to containing two essential elements, nitrogen (N) and sulfur (S), it plays a vital role in plant growth and yield. Its granular form ensures easy application, uniform distribution in the soil, and longer shelf life compared to other forms of ammonium sulfate.
What is Granular Ammonium Sulfate?
Granular ammonium sulfate is a mineral salt produced as white or grayish granules. This fertilizer is used to promote plant growth and improve the quality of agricultural products due to its nitrogen and sulfur content. The granular form facilitates uniform spreading in large fields with fertilizer spreaders while also having extensive applications in other industries.
According to the Food and Agriculture Organization (FAO), nitrogen fertilizers like ammonium sulfate play an essential role in increasing crop yields in nutrient-poor soils. In Iran, where alkaline soils are common, this product improves nutrient absorption such as iron and zinc by lowering soil pH (source).
Difference Between Granular and Crystalline Ammonium Sulfate
Although granular and crystalline ammonium sulfate are chemically similar (21% nitrogen and 24% sulfur), they differ in form and application:
Physical Form: Granular is supplied as larger granules, while crystalline is fine, shiny crystals.
Dispersibility: Granular is better for uniform spreading with fertilizer spreaders in large fields, while crystalline is ideal for foliar spray and drip irrigation.
Dissolution Rate: Crystalline dissolves faster in water, while granular dissolves gradually, suitable for sustained plant nutrition.
Industrial Use: Granular is preferred in some industrial processes requiring uniform distribution.
