The potash in Fibrophos is less soluble than inorganic fertilisers (50% water soluble), so 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 muriate of potash. Any potash remaining will become available to the plants
in the longer term, making Fibrophos a very effective fertiliser for grass and arable situations.
The potassium content of Fibrophos is very quickly available and in trials has been found to be
90 to 100% as effective as that in muriate of potash.
Because the Potash is available in line with crop growth demands, plants become healthier and
stronger. Since these early trials conducted in 1994 over 800,000t of Fibrophos has been sold
nationwide for both cereal and grassland applications – the vast majority of sales made today
(>80%) are to farmers who have used Fibrophos across their farms for the past 18 years - thus
endorsing the work carried out by ADAS |
| How do we know fibrophos does what is claimed?
Over the past 20 years, formal trial work has been systematically
carried out to establish that the product performs in yield and
quality terms as well as Triple-Superphosphate (TSP) and Muriate of
Potash (MOP) – both of which are used as standards. Using a variety
of well respected research bodies, it was confirmed that the
phosphate and potash in Fibrophos are as effective as TSP and MOP
across most soil pH levels. In some cases the potash in Fibrophos
was shown to demonstrate less antagonism than that of muriate of
potash. The work further demonstrates the added bonus of
Fibrophos with increased performance from the other major and
minor nutrients also present. |
