Tempted to get some N on, early and cold but conditions are superb and early N always delivers in my opinion. Anyone else?

Most of the barley not looking like it needs any yet .

Maybe a bit on 2nd wheats on some strong wet land if conditions are perfect but that’s about it

We’re doing a little bit, mainly to train a new relief operator before we really get going.

Doing some DAP this morning on wheat after oats and 2nd wheats. Don't want to put any serious amount of N on yet, but with just ammonium N in the DAP and not so much of it I am happy to do a bit. I think on heavy land early N helps to get the biomass in the crop that often we lack if left too late.
Too early. I hope the doses are small. I don't see any crop making use of more than a few kg of N for at least 6 weeks yet. There's a lot of winter left, short days, cold soils & leaching potential. Most of the neighbours are still on P and K doses.
I plan to start on backwards osr in 3 weeks depending on conditions. Wheats can wait longer. Nothing looks hungry yet.

Exactly, winter barley is usually the first indicator and I haven't seen any yellow crops yet. Still waiting for the rainfall to balance out this long dry spell, if it comes any applied N will be gone before the crop starts looking for it.
I have some very yellow barley (which is normal) but all I did was use the dry weather to give it a tickle of Mn a fortnight ago which I think was more helpful.

Maybe we are being too keen. I wonder if anyone has any comments on this slide from Neil Fuller I saw a while back. On high CEC clay soils with a lot of negative cation capacity, i think the NH4+ ions will be fairly strongly bound and hence not that leachable. Crops have established very well and will have larger root systems than average I am assuming.

And people complain about being put in nvz zones due to high levels of nitrates in rivers!

Difference between NO3- and NH4+. There are no Ammonium Vulnerable Zones. Although it will convert, this process is very slow at this stage IIRC. People always like to forget the difference. I recall @York doing some German trials where they put ammonium sulphate on in the autumn in quite large amounts on heavy high CEC soils and could not measure any appreciable leaching over control.

Lash it on then, if you think no leaching is going to occur.

Tell me why I'm wrong with a reasoned argument and I'll quite happily be convinced. As I said, we did a small bit this morning with largely a phosphate product on soils which are much more capable than yours of holding onto it. I might be wrong, but so might you!

Same here, even the Barley doesn't look hungry.
