USES:
It is used largely as an
artificial fertilizer for
alkaline soils. In the soil
the sulfate ion is released
and forms sulfuric acid,
lowering the pH balance
of the soil (as do other
sulfate compounds such as
aluminium sulfate), while
contributing essential nitrogen
for plant growth.
It is also used as an agricultural
spray adjuvant for water
soluble insecticides, herbicides,
and fungicides. There it
functions to bind iron and
calcium cations that are
present in both well water
and plant cells. It is particularly
effective as an adjuvant
for 2,4-D (amine), glyphosate,
and glufosinate herbicides.
It is also used in the preparation
of other ammonium salts.
In biochemistry, ammonium
sulfate precipitation is
a common method for purifying
proteins.
Ammonium sulfate is also
a food additive. |
