The P&K is slow release, does this
mean it won’t work quickly enough
at low indices??
Not at all. The P&K are in both
immediately available and
sustained forms, providing nutrient
throughout the growing season.
Extensive trials have shown that
Fibrophos is a very effective source
of phosphate across a wide range
of agricultural soil types throughout
the UK. The phosphate in Fibrophos
is more than 80% soluble in 2%
citric acid and nearly half is soluble
in neutral ammonium citrate
providing a long lasting as well
as immediate supply to the
growing crop. Trials showed that
application of Fibrophos to both
acid and alkaline grassland or
arable crops significantly increased
available soil phosphate within
one month and this increase was
maintained for at least 12 months.
Citric soluble phosphate helps build
up soil fertility over time.
The potash in Fibrophos is less
soluble than inorganic fertilisers
(50% water soluble), the uptake of
potash is less rapid, avoiding luxury
uptake that can cause staggers.
ADAS trials carried out by ETSU for
the DTI confirmed that the potash
is very quickly available and is as
effective as MOP. Any potash
remaining will become available to
the plants in the longer term,
making Fibrophos a very effective
fertiliser for grass and arable
situations. Because the potash is
available in line with crop growth
demands, plants become healthier
and stronger.
Since these early trials well over
1 million tonnes of Fibrophos has
been sold nationwide for both cereal
and grassland applications.
Many of the sales made today are
to farmers who have used Fibrophos
across their farms for over 20 years -
thus endorsing the work carried out
by ADAS.
Will the trace elements make
much difference?
Trace elements are essential
nutrients for all growing crops
and need replacing. Acute trace
element deficiencies need
supplementary treatment but
regular applications of Fibrophos
will enrich the mineral
composition of the soil.
Fibrophos puts back trace
elements in the same proportion
as they were initially removed –
because it is produced from
combusted (cereal rich)
poultry manure.
