Ammonium sulfate (AS) is the earliest nitrogen fertilizer produced and used. Usually used as a standard nitrogen fertilizer, the nitrogen content is between 20% and 30%. It's a very important fertilizer for any kind of soil that has a high pH and needs a little sulfate to fight high calcium or high pH. The good thing about ammonium sulfate is that the nitrogen in it is released slightly more slowly, so it lasts better throughout the growing season than the nitrate form of nitrogen.

PRODUCT USAGE

Ammonium Sulfate is an excellent nitrogen fertilizer and an important industrial raw material. In agriculture, it is a classic physiologically acidic nitrogen fertilizer that provides essential nitrogen for plant growth. Its sulfur content is vital for sulfur-deficient soils and sulfur-loving crops such as onions and garlic, significantly boosting both yield and quality. In the industrial sector, it is extensively used in rare earth mining as an ion-exchange agent to extract rare earth elements from ores. In the food industry, it serves as a dough conditioner and yeast nutrient to improve the texture of bread. Additionally, it is applied in pharmaceuticals for protein purification (salting-out), as a deliming agent in leather processing, and as an additive in flame retardant materials.
