Global demand for sulphur for agricultural use
has grown rapidly in recent years,
as farmers seek to replace the
sulphur that was previously deposited
as “ free
nutrient ” from the atmosphere. The
natural supply of sulphur has dropped as a
result of more efficient cleaning of industrial
gases from power stations, chemical plants and
other industrial sources, as well as
through changes in the practice of fertilizing .
This has in turn been
compounded as demand for
sulphur has increased in line with
increasing expectations of yield per
hectare of agricultural land.
|
Elemental sulphur, although
available in large quantities,
cannot be used as
nutrient, mainly because it is not soluble in
water. A granule of elemental sulphur
therefore takes very long time before it release
into the soil. One solution to this
problem has been to combine elemental
sulphur with Bentonite, a type of
clay
which increases its volume by factor
of 3 to 5 when it comes into contact
with
water.
|
When a sulphur Bentonite granule
( Googerd90 ) comes into contact
with soil
moisture, it breaks apart into fragments
of dust-dimensions, thus allowing
swift
and continuous solubilisation. With its unique
formulation, Googerd90 delivers the
best swelling and distribution properties within
the pastille sulphur market.
|
The use of elemental sulphur
in a degradable granular
from – produced by
mixing with approximately 10% Bentonite clay- is
becoming very popular as high
application rates of 50-70 kg/hectare
are required and the pastille form is easily
applied , either by mechanical means or by hand.
|
Googerd 90 produced on a ZAFARAN
system is consistently sized, free flowing
and easy to handle, store and apply. The
product has very low dust content and
therefore complies with the highest
environmental standards.
