One important use of ammonium salts in agriculture is as a fertilizer. Ammonium salts, such as ammonium sulfate and ammonium nitrate, are commonly used to supply nitrogen to crops, which is essential for plant growth. Nitrogen is a key component of amino acids, the building blocks of proteins, and is integral to chlorophyll production, which helps in photosynthesis.

In agriculture, fertilizers help enhance soil nutrient content, thereby improving crop yield and quality. Ammonium salts are advantageous because they can be readily absorbed by plants and can improve the soil structure as well. They are particularly beneficial in areas where nitrogen-deficient soils are a concern, making them a staple in agricultural practices worldwide.
