Phosphate in Fibrophos

Phosphate availability – dispelling the myths

As we move towards a far more environmentally focussed form of farming with future support payments likely to be linked to tighter controlled friendly farming, it is becoming critical that we focus on efficient use of fertilisers – particularly phosphate which is the dominant cause of agricultural water quality failure.

This is the drive behind new ongoing research from AHDB into understanding how phosphate works in our soils. Early results have surprised the traditionalists who have for years peddled the myth about the importance of water soluble phosphate as supplied by TSP. The report has revealed that:

‘The recovery rate of TSP by the first crop is just 4% – the vast majority of the phosphate applied goes into the reserves of fixed P in the soil, which is unavailable to plants and only released very slowly’.

Other forms of traditional phosphate, treated phosphate or fertiliser placement in the trial ‘proved to be little better than TSP’.

These results should come as no surprise to the thousands of farmers who have been using Fibrophos PK Fertilisers across their farms as their sole P&K source for over 20 years. They endorse the evidence that the phosphate in Fibrophos is available to the crop as required and goes on working year after year to help maintain adequate indices for today’s heavy demanding crops.

Chief ADAS scientist Prof Roger Sylvester-Bradley, head of Crop Performance for ADAS, who is conducting the report admits that this information has been a long time coming as trials on phosphate take a very long time.

The report does acknowledge that different soils act in different ways – calcareous soils require P on a more regular basis for instance. It also suggests that in order to protect our environment from excess run off, we need to avoid wasteful over application of expensive phosphate and replace with those more effective sources. This may mean allowing our soils to fall below the recommended index of 2 provided we have the confidence that the levels in the soil phosphate bank is not yield limiting.

This could be achieved in the future as the trials suggest that 80% of the phosphate taken up by the crop comes from the soil rather than applied fertiliser – so further highlighting the need to ‘feed the soil’ with an effective good value fertiliser less damaging to the environment.

With Fibrophos offering a real alternative to traditional thinking, it certainly fits the bill in terms of cost savings – and comes with the added bonus of a wide range of trace elements, Calcium, Magnesium, Sodium and Sulphur. There is also a good range of trace elements – all at no extra cost.

With Fibrophos PK Fertiliser offering so much, why pay more?

How is Fibrophos delivered and will it spread evenly?

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.

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.

Find out why incinerated poultry manure is better

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.

Find out what makes Fibrophos different from similar products

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. Fibrophos Ltd are members of the AIC and all product is sold under FIAS regulations so you may be assured that you get what is declared on the Statutory Statement which accompanies every load. Beware of other fertilisers which are not sold in this way.

Will the trace elements in Fibrophos 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.

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.
