Description and Uses
Ammonium sulfate was the first
nitrogenous fertilizer made by the Haber-Bosch process,
produced by the reaction of ammonia with sulfuric acid. In
contrast with the nitrate salt, it is chemically stable, not
highly hygroscopic. It also supplies supplemental sulfur to
soils that may be deficient in this element, but this is of
minor value when it is used on soils receiving applications
of ordinary superphosphate.
The disadvantages of the
material are its relatively low nitrogen content, which
increases storage and transportation costs, and its marked
tendency to cause soil acidification, which is greater than
that of any other nitrogen fertilizer material.
May be used for the precipitation or fractionation of proteins or for purification of antibodies. Useful for crystallographic analysis of nucleic acids and proteins.
