Ammonium Sulphate is a quick acting acidic fertiliser. It contains 20.5 % Nitrogen, most preferred source of nitrogen in Paddy crop. There is no loss of Nitrogen through leaching. As Ammonium Sulphate is resistant to leaching it is more suitable at the time of planting. It contains 23 % Sulphur to take care of the crop’s Sulphur requirement, helps the crop to utilize Nitrogen efficiently due to the presence of Sulphur.
Growers apply ammonium sulfate primarily where they need supplemental N and S to meet the nutritional requirement of growing plants. Since ammonium sulfate contains only 21 percent N, other fertilizer sources more concentrated and economical to handle and transport often make a better choice for N-deficient fields. However, it provides an excellent source of S, which supports or drives numerous essential plant functions, including protein synthesis.
Ammonium sulfate is also used:
in the production of viscose fiber;
in biochemistry, reprecipitation with ammonium sulfate is a common method for purifying proteins;
as a food additive E517 – emulsifier;
in water chlorination technology;
upon receipt of manganese.
