FIBROPHOS FAQ'S

What Our Customers Ask

What is Fibrophos?

Fibrophos is an environmentally friendly, renewable PK fertiliser consisting of phosphate, potash, sulphur, magnesium, calcium, sodium and significant quantities of essential trace elements required by crops and grass to achieve high yields.

What are the major benefits of Fibrophos?

Fibrophos provides P&K in both immediately available and long lasting forms, providing available plant nutrients throughout the growing season and also replenishes nutrients removed to improve soil fertility.

Fibrophos recycles nutrients removed from agriculture back into agriculture so reduces amounts of nutrients mined and the environmental costs of transporting them.

The type of potash and magnesium contained in balance reduces the risk of grass staggers. Fibrophos contains calcium and sulphur, so helps maintain pH & soil structure, maximises the uptake of nitrogen and improves protein synthesis. Sodium will improve the palatability of grass and help maintain healthy pastures.

Trials have shown uptake of magnesium better with Fibrophos than where TSP and MOP applied.

How does it work?

It’s not a blend but it replaces nutrients in the same ratio removed by the growing crop. The immediate effects are a big PK boost. Unlike some other fertilisers there is a longer term benefit with the release of nutrients steadily over time, building balanced, stable soil and healthier, stronger crops.

How is Fibrophos Produced?

It comes from predominantly deep litter poultry manure from cereal fed chickens, which is incinerated at 850°C in biomass power stations, producing a safe, pathogen free, ash by-product which is conditioned into a pure agronomically effective fertiliser containing all the plant nutrients (except nitrogen) which were present in the poultry feed.

How long has Fibrophos been produced?

For over two decades arable and grassland farmers have seen the benefits of Fibrophos and demand grows year on year. Research has confirmed that the phosphate and potash in Fibrophos is as effective as TSP and MOP and that secondary and trace elements offer an additional bonus. It works and it works very well.

The PK 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 that inorganic fertilisers (50% water soluble), the uptake of potash is less rapid, avoiding luxury uptake that can cause staggers. ADAS trials carried out by the 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.

There are other, similar products on the market. What’s different about this one?

Fibrophos is produced from burning the same consistent fuel source all the time. This means the physical quality and nutrient analysis of the product do not vary. It’s the same time after time.

I’ve used poultry manure as a fertiliser. Why should I want it burnt to an ash?

Firstly, incineration ensures there are no pathogens. Secondly, poultry manure cannot be applied during the wet winter months due to problems with nitrogen leaching – the manufacture of Fibrophos takes poultry manure throughout the year thus avoiding leaching issues. Thirdly, by creating a consistent quality ash product it makes it easier to spread accurately.

What about traceability of the poultry litter fuel source?

Fibrophos is sold under a Quality Protocol for Poultry Litter Ash (PLA) set by the Environment Agency. The poultry litter fuel is only sourced from British poultry farms and is closely monitored for chemical composition and every delivery to the power station can be traced to a particular poultry farm from which it came.

At 18% calcium, 4% magnesium and a neutralising value of 15% is it just expensive, low grade lime?

No. The calcium and magnesium are in readily available forms and are valuable plant nutrients. Fibrophos is not a liming product but, when used regularly, will help maintain soil pH.

How does Fibrophos compare with the cost of other fertilisers?

Fibrophos is competitively priced with all P&K fertilisers across the UK. In addition, the secondary and trace elements in Fibrophos are supplied at no extra charge so provide a cost effective way to replace nutrients removed or to correct deficiencies in your soil – giving you peace of mind.

How does Fibrophos benefit the environment?

Fibrophos is naturally produced from totally natural and organically derived origins, using renewable sources of chicken litter and wood waste such as bark and chippings. Its use as a fertiliser replaces mined phosphates and potash which are costly on the environment to both mine and import.

The power stations generate in excess of 100MW of renewable electricity, helping reducing the reliance on non-renewable sources of oil and coal. Because the carbon in the litter was fixed from the air recently, burning it does not add new carbon dioxide into the atmosphere so helps reduce accumulation of greenhouse gases.

Is it approved for organic use?

No. Although derived entirely from organic material, it cannot be used on organic farms as the poultry litter is not exclusively from organic farms.

How is Fibrophos delivered?

Fibrophos is a bulk fertiliser available for delivery or collection across the country – typically in bulk 29t loads.

It is ideally tipped on a hard, free draining surface, just prior to time of application. It is weather proof and stands getting wet. Being delivered in bulk there are no bags or packaging to dispose of or recycling costs.

Will it spread evenly?

Absolutely no problem. We have taken great care in handling and treatment of the product to ensure it arrives on farm in excellent condition, suitable for accurate and even spreading.

How is it applied & what are the typical application rates?

Fibrophos is a coarse powder and therefore should be spread using a contractor with the appropriate experience and equipment for spreading this type of material. It is recommended to employ a trailed spreader with a moving belt floor system or similar, such as those found on Atkinson, Bredal, Land Drive or Transpread machines.
