Ammonium sulfate

Ammonium sulfate is made by treating ammonia often as a by-product from coke ovens with sulfuric acid: 2 NH 3 + H 2 SO 4 → (NH 4) 2 SO 4 A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2 to 4% of free sulfuric acid at 60 C Concentrated sulfuric acid is added to keep the solution acidic and to retain

Ammonium Sulfate

Ammonium sulfate has an acidifying effect on soil due to the nitrification process not from the presence of sulfate which has a negligible effect on pH The acid-producing potential of ammonium sulfate is greater than the same N application from ammonium nitrate for example since all of the N in ammonium sulfate converts to nitrate compared with only half of the N from ammonium nitrate that converts to nitrate
