I know what's in methylene urea.

I can't find the MSDS for polyN plus.

Uf / urea- methal / methylene urea slow release fertilisers etc have been widely studied and reviewed.

anyone used it?
I tried an ibc of it about 2 years ago from BFS , used it from GS 32 onwards and didn't find it that good. About 1/2 the response of solid N. Trials were done in Wiltshire using it as the sole source of n and from what I heard it wasn't that successful, so I should try it cautiously, not all or nothing!

It sounds like a good product. Safe and efficient. The problem is the price - I was quoted £1500/ 1000l ibc. Use at 25l/ha x 2 is the equivalent to 175kg/ha Nitram. Saves a pass with the fertiliser spreader but costs almost twice as much! I’m keen to try it but not at that price.

have you costed the outcome ?Or, have you allowed for the value it creates vs the cost ? It doesn’t work anything like “fert” and shouldn’t be compared to it. It’s way more efficient, but needs to be understood.

The way I’ve calculated is based on the BFS claim that 2 applications of 25l/ha of polyNplus replaces 60N of prilled/granular product. The cost of 50l of polyNplus is £75. 60N equals 175kg of Nitram etc. depends on what you paid ... in my case £34 plus £9 for the pass with the spreader. Even if you use the current price of Nitram it’s £50 plus £9. If an ibc of polyNplus cost £1000 rather than £1500 then I’d give it a try.
Have I missed something?

Do Agro-Vital deal direct or through merchant?
I think they deal direct I did get a price off them at groundswell

Agro-Vital are wholesalers but we have distributors across the country. Here is a bit of information about our product:

1) it is 28% N of which 22% is made up of urea polymer and the other 6% is urea - this is the highest percentage of polymer available. Much lower tendency to scorch and greater efficiency than competitors.
2) When bought as IBCs its RRP is £1.52 per kg and the recommended rate is 25 kg / ha (= 20 L/ha = 7 kg N/ha)
3) 20 years of trials have shown that you can replace 40 kg N / ha from granular fertiliser with 7 kg N/ha from EfficieN28t.
4) tank mix compatible with most plant protection products and PGRs - although some care should be taken with trinexapac-ethyl products.

any questions please let me know on here or at [email protected]

Thanks

Have I followed correctly? 25kg per ha costs nigh on £40 and can replace 40kg N of granular. Sounds expensive to me, especially if you can't mix with moddus.

Hi, you are right that 25 kg/ha would cost about £38 and that can replace (or do the equivalent work of as an addition) 40 kg N/ha from granular.

That 40 kg N/ha is equivalent to 116 kg/ha of ammonium nitrate or 87 kg/ha of urea

if AN costs, for example £250 / tonne then the cost of 116 kg/ha is £29 /ha compared with £38 /ha from EfficieN28t
When AN is £275 / tonne that will cost you £31.90 / ha compared with £38 / ha from EfficieN28t

But you should also consider that nitrogen use efficiency (NUE) from AN is only 40 - 60 % so you are effectively throwing half of it away (into groundwater?). EfficieN28t is as close to 100% NUE as makes no difference and the crop does not have to use 15% of its energy converting nitrate to plant-usable N as it would if you apply AN.

Another thing to consider is that, should it go hot and dry in spring, any solid fertiliser is going to sit there until there is enough soil moisture for it to be taken up. EfficieN28t goes straight onto the leaf then straight into the plant.

Other benefits are that you do not get scorch, you reduce lodging risk as there is no nitrate flush of soft growth and you are not damaging the micro-organisms in the soil that contribute to soil health.

EfficieN28t is a premium product but you are getting every bit of N from it when the plant needs it. I would not suggest that all granular N can be replaced by it but it is a serious consideration when looking at the challenges involved in feeding and keeping a crop healthy whilst limiting environmental impact.

Sorry about the long sales pitch but I hope that I answered your point. I am happy to send out any trials reports should you want them.

Sorry - just seen you mentioned Moddus. The recommended application timings for EfficieN28t are 20 L/ha at T2 in winter wheat to build yield or at T3 to build protein. You can use it as soon as there is canopy as part of a programme that reduces overall granular N (this is popular in the Netherlands) but it is unlikely in practice that there would be any need for a tank mix with Moddus.

Thanks for the detailed answer. I read it that the NUE of Urea/AN was already factored in to your third point:

3) 20 years of trials have shown that you can replace 40 kg N / ha from granular fertiliser with 7 kg N/ha from EfficieN28t.

So who can we buy it from then I’m in Northampton and how much for a ibc

Just resurrecting this thread, with the price of fertiliser going through the roof, these foliar fertiliser products will be more comparible on price.I don't know anyone around me that has used them, so has anyone used them this year and how did you get on with them?
