NIAB trials? If it works it could be a useful way of increasing N use efficiency as I have little doubt that we will have top dressing fertiliser restricted and taxed heavily in the future.
I agree. Whether we like or not, we have got to find ways to use less N and to use the safest forms for the environment. It’s certainly high on my agenda and if products like this perform as claimed then I’ll adopt them. Does anyone know how it’s priced?
 
the problem with all reductions in n from the optimum is that eventually the protein content of the wheat will be lower

so milling wheat for bread or biscuits will be come harder to meet the spec

with optimum rates for yield the last 30 kg of n does not increase yield very much but does pay a return

with the products that give a small amount of n replacing a bigger amount of fertiliser n
if the yield stays up there will be less n in the system
either grain n falls or the n in the crop residue left in the field is lower

this will eventually lead to lower amounts of n in the soil

i have found on my heavy land over the last 40 years that increasing yields continuous cropping no manure the amount of n available from the soil has reduced less lush forward crops in the autumn is a sign hard to make 13% milling wheat
there is only so much organic matter in the soil and eventually with out enough n it will reduce to very low levels

products may maintain the yield by utilising the n that comes from the surplas organic matter in the soil with a soil that has not had years of intensive cropping

Yes, looks very promising in NIAB trials, I’ll do some tramline trials in Wheat abs S Barley this spring
I totally agree, products like this are what we will need to adopt to balance output and environmental costs, should mix in with fungicide too so should cut passes as well, leading to more carbon savings...
I was looking at buying a new spreader, but with the future of Urea looking doubtful and Poly N looking promising I’ll hold on for a bit !!

Poly N plus - i recommend it on a wide range of crops. Great results in milling wheat, WOSR and Maize. You have to put enough on to get a response, and at the right time. Tank mixes well, and never caused scorch.

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.

What is it? Urea with....? Or a different urea?

I tried google but it just pointed me to this thread and a 2018 one 🙃

That’s the problem, double the efficiency = double the price, tick the carbon box but be no better off...
I’m sure it will become slightly better priced product with some market share and the whole industry will benefit??

I wish I could share your optimism ! It might become a reality if there are several manufacturers fighting it out for market share but in the meantime it will be a niche product with a price tag to match. It certainly ticks the ‘green’ box compared to the usual sources of N but it needs to be more economically priced for farmers to embrace it. I think Billericay Farm Services could have a fantastic money spinner here but in my opinion they need to be more aggressive with their marketing.

Yes, I totally agree with you
BFS will see the huge potential of the market they can take from CF and prices will fall because it’s ridiculously priced at the moment

( I am an eternal optimist 😂 )

Hello, I’m Janet Hughes. I’m the Programme Director for the Future Farming and Countryside Programme in Defra – the programme that’s phasing out the Common Agricultural Policy and introducing new schemes and services for farmers.



Today (20 September) between 7pm-8pm, I and some of my colleagues will be answering your questions about our work including the Sustainable Farming Incentive, Farming in Protected Landscapes, and our test and trials.



We’ll try to answer at least 15 of your top voted questions, so please vote on the questions you’d most like me to answer.



You can read more about our Future Farming policy on our blog.



I’ve answered some of your questions previously: you can watch the videos on...
