Ammonium Sulphate: Significance in Indian Agriculture and Soil Nutrient Management

Ammonium Sulphate

Context

Recently, the Indian Council of Agricultural Research (ICAR) recommended the use of ammonium sulphate for paddy cultivation as a low-cost fertilizer option to help farmers improve crop nutrition and maintain soil fertility.

About Ammonium Sulphate

  1. Ammonium sulphate is an inorganic sulphate salt formed through the reaction of ammonia with sulphuric acid.
  2. It is widely used as a fertilizer because it supplies essential nutrients required for plant growth and soil health.
  3. The compound contains nearly 21% nitrogen and 24% sulphur, making it an important source of nutrients for crops.
  4. It is particularly beneficial for alkaline soils as it improves nutrient availability and supports better crop productivity.
  5. Ammonium sulphate is a white, odourless crystalline substance that is highly soluble in water and has a high melting point.
  6. It is also produced as a by-product in steel plants through the recovery of coke oven gas, along with certain chemical and metallurgical industries.

Applications of Ammonium Sulphate

  1. Water Treatment: Used in water purification and treatment-related processes.
  2. Food Industry: Acts as a food additive and dough-conditioning agent.
  3. Pharmaceutical Industry: Applied in various pharmaceutical and biochemical processes.
  4. Textile and Leather Sector: Used in dyeing, printing and leather-processing activities.
