Ammonium sulphate – Amsul

Ammonium sulphate, often referred to as “Amsul,” is an inorganic salt with the chemical formula (NH4)2SO4.

Ammonium sulphate can be produced by reacting ammonia gas (NH3) with sulfuric acid (H2SO4). It is also a byproduct of various industrial processes, such as the purification of coke oven gas, the production of caprolactam (a precursor to nylon), and as a byproduct of certain metallurgical operations. It is highly soluble in water, which makes it suitable for use as a water-soluble fertilizer.

Ammonium sulphate is commonly used as a nitrogen fertilizer in agriculture. It provides a readily available source of both nitrogen and sulphur, which are essential nutrients for plant growth. The sulphate ions contribute to soil fertility by supplying sulphur, which is necessary for the synthesis of certain amino acids and proteins in plants.

Ammonium sulphate is sometimes used to acidify soil or water due to its acidic nature. When dissolved in water, it produces ammonium ions and sulphate ions, which can lower the pH of the solution. This property makes it useful for crops that prefer acidic soil conditions.
