Similar to ammonium chloride, ammonium sulphate is another nitrogen-rich fertilizer commonly used in crop production. It provides both nitrogen and sulphur nutrients to plants, promoting their healthy growth and enhancing the quality of crops. It is particularly beneficial for crops that require high levels of nitrogen, such as corn and wheat.
Ammonium sulfate is used as a fertilizer because it supplies nitrogen and sulfur for plant nutrients.
