Ammonium Sulphate is a nitrogenous fertiliser containing 20.6% nitrogen, entirely in ammonical form. It has excellent physical properties; non-hygroscopic, crystalline and free flowing. It is ideal as a straight nitrogenous
fertiliser and also as an ingredient in fertiliser mixtures. It is the most widely preferred nitrogenous fertiliser for top dressing on all crops. Another unique advantage is that it contains 24% sulphur, an important secondary nutrient.
