FEATURES
Sulphate of ammonia is commonly used as a source of nitrogen and sulphur.
Prior to the general acceptance of Urea in the ***0s,
Sulphate of ammonia was the main source of nitrogen.
It has good storage and handling qualities, and
can be readily blended with other fertilisers.
It has the desirable agronomic features of being a source of both nitrogen and sulphur.
Higher nitrogen cost can be one of the main factors limiting the use of SOA,
however, if the value of the available sulphate sulphur is considered it can be good value.
USES
SOA is a valuable fertiliser as a straight product or in blends.
Sulphur in SOA is sulphate sulphur which is the form taken up directly by plants.
Sulphate sulphur is readily soluble in water and goes straight into solution
when applied to the soil (providing there is moisture).
SOA releases nitrogen to the soil directly as ammonium NH4+,
which is converted by bacteria to nitrate nitrogen. This process is favoured by conditions conducive
to microbial activity, such as warm temperatures, moisture and organic matter. The rate of this reaction
depends on those conditions and complete nitrification of applied ammonium can vary from a
few days to several weeks.
Apart from leaching losses, the other source of loss is volatilisation from
the soil surface. These losses vary with the prevailing conditions.
Losses will increase under the following conditions:
Benefits of Ammonium Sulphate Granular
a)Provides an equal balance of nitrogen and sulphur
bMeet short term sulphur deficits of crops and pastures
cThe safest nitrogen fertiliser to mix with non Superphosphate based fertilisers
d)Volatilisation of ammonia from Ammonium Sulphate
is very low compared to Urea, therefore the timing of the application is flexible
Ammonium Sulphate Granular provides an equal balance
of nitrogen and sulphur that is readily available.
Storage and Transportation
Ammonium Sulphate should be stored in cool, dry, ventilated warehouse, avoid to be exposed in sunshine, rain, and high temperature.
During the transportation: avoid shipment with acid, alkali stuff, prevent it from sunlight and rain and do not damage the packing bags.
