BFS PolyN – too good to be true?

[Feldspar]

Anyone have experience using Billericay's new PolyN fertiliser which is methylene urea?

The claims about it, which they accept themselves, seem too good to be true. The claim is that because of the near extremely low scorch risk that you can apply a fine spray onto the leaf. Because of this, and due to other effects of the chemistry, they have been trialling applying around 25% of normal N rates using this methods and have been getting good results.

Sounds to good to be true, but would like to think it works

Is this another wonder product with lots of BFS sales PR, but no proper trials data??

I am doing my research at the moment into what research (within academic circles) has been done on it. Have asked for their trials data.

Conventional fertiliser N from any source is a very inefficient way of getting N into the plant. Maybe this fertiliser is a much more efficient way of doing this? Normally things that sound too good to be true are just that but I will watch this very closely, chances are it will be 3X the price of normal fert anyway.

I used a fair amount of poly-n last year. Here is my observations:
1. You need a full canopy to intercept the product when sprayed.
2. It will mix with most fungicides. I did not mix any herbicides with it as i did not want to kill the crop by accident.
3. This product will get yield but not help proteins as their is not enough N getting in the plant. Could be brilliant for malting barley.
4. BFS will mix other goodies such as Mg, S, and Mn on request which makes it very useful in some deficient soils.
5. We worked on the principle of 30 lts/ha giving the same yield response as 50kg/ha bagged N.

Going forward next spring i am probably going to add some every fungicide pass from T1 on top of the 150 to 200 kg of standard liquid N.

Are they not based at ilgars farm by south woodham ferrers. Imagine the phillpots will have tried it and give a honest appraisal.

Thanks for response.

I am interesting that you are going to add it on top of an amount of standard liquid N that many would use as their total N. Do you think then that it is not suitable for replacing a significant % of the total season N application. From the way it was explained to me it sounded like you could apply 50 kg/ha of PolyN and that would equate to having applied 200 kg/ha N of normal urea.

How does the cost compare to standard liquid N ?

In theory yes could apply 50kg of polyn and get equivalent yield. But remember it has to be intercepted by the leaf to have any benefit. If urea is on average 60% available this potentially is 95% available. Price wise it was more expensive than uan but you need a lot less and it has the potential to be mixed with fungicide applications saving a whole pass with fert spreader.

How much more expensive is it ?

Ie is there any saving per same kg/ha N applied ?

Good question. I would expect it to trade at a premium in pence/kg N and try and sell it on the benefits of ease of applications/less storage required, then no doubt throw in a trial result showing a potential yield increase.

Methylene urea - widely used for golf courses etc - good slow release and no scorch. Interested to hear it might be economic for farm crops.

Price wise last year worked out very similar to equivalent application of uan. Going through field records today i missed out a whole pass of uan at the end of april and applied this material with t1. Reasons. for this was we were in middle of drought and used as a tool to get nutrition into plant as no rain to wash in conventional fert. It certainly perked the crops up until rain eventually came in mid May.
