Nitrogen question

[le bon paysan]

Split dose 2/3 1/3 or all in 1. It's urea. 300 kgs/h.

 

[Spencer]

Crop?

 

[teslacoils]

All in one.

Depends on your rainfall, if you get a lot march and april then a split would be fine if you dont I would get all mine on by beginning of April, we put a few kg on the last frost, half the rest asap and the rest first few days in april unless a decent amount of rain is forecast, all urea too

 

[le bon paysan]

Crop?

Wheat.

 

[Spencer]

All in one considering your location would be my take on it..

For milling wheat ?

Missed where it said milling?

They don't grow feed wheat in france , not intentionally anyway

Well if he doesn’t get his Urea on early before drought kicks in he’ll have neither

 

[Boysground]

If I ever make a cock up with nitrogen it’s when I’m going all in one dose. Always a split dose for me

It so depends on where you are, the climate/temperature and expected rainfall with Urea.
Here, which I think is 300 miles north of you, is probably colder and wetter. I go for 1/3rd on in Feb as soon as I can travel on a Frost, then all the balance on by 7th April.
This is to ensure it has a better chance of it all being used by the crop, because it is slower acting than AN.

However, I’ve actually switched to using Doubletop as the first dressing. Which still puts about a third of my total N on, plus Sulphur.
One of the reasons for doing this is that Urea is very temperature respondent and sometimes does not act fast enough to wake my crops up soon enough.

In your situation in Limousin, I would definitely think you might want to get it on sooner than me. If your expected rainfall isn’t high, then all in one go now, might be the best idea.

I’ve been using Urea for over 40 years. It is a myth about it leaching any more than AN, in fact it is less so.
Also, it is a myth about it volatilising on anything except bare ground where temperatures exceed 27 degrees centigrade.

There are many countries in the world that do not allow AN as it is (and was invented as an) explosive when mixed with an accelerant, such as Diesel or sugar.
Those, which are almost all hotter Countries, are only allowed to use Urea.
Although IIRC, I don’t think they can use AN in Ireland.
Nor can they in India. But worryingly, they can in Pakistan!

Are you allowed to use AN in France?
I’d definitely want to use Urea anyway, because it is cheaper and IMO, just as effective, if not more so!


I assume the 300Kgs/ha you mention is 300Kgs of 46% Urea, being 138Kgs of N/ha.
What yield do you expect from that dose rate on your Wheat?
Here, I would expect IRO 7.5ish tonnes/ha from that level of N.

Would I be right in suspecting that your disease levels would be very much lower than here too? Requiring few, if any fungicides?


I’d love to know more from you as to the Varieties you use and expected harvest dates. June/July?

We have tended to put a larger dose on for the first dose, it tends to safeguard against a dry Spring, and then I tend to split the rest, so 3 doses with the last as late as I can get away with. Chap next door does the same after we compared notes, using Urea here too.

That’s very interesting.

I assume your land is Brash and more prone to drought than here, so can see the logic behind your larger first dose.
My only question is why do you split Urea into 3 doses? (Assuming you are not referring to a final dose for milling wheat as dose 3).
I’ve always found that it works so much more slowly than AN. So I want it all on sooner, combining the last 2 doses as one.
However, If I was forced to use AN, I’d go with 3 doses (not including the last extra dose for milling wheat).

But if it works for you, don’t let me put you off!


BTW, I have used Urea as a very late dose of N on Milling wheat to raise the protein, in late May. And it works!

But, I became so sick of inevitably waiting for “The Claims phone call” after each lorry that left the farm for anything (usually moisture or bushel weight) they hoped would let them have it cheaper, that I now only grow higher yielding feed wheat that I personally deliver to a local Mill and earns me in reality as much income, but without the hassle! They take it up to 16.5% without me drying it for claims less than half the cost I could dry it for.

Yes milling wheat.
AN is at the moment 25 euros a tonne cheaper, 290 v 315.
Target 6/6,5 tonnes hectare but straw is an important by product.

[bobk]

3 doses last one liquid ideally , 300 kg is a big amount imo

 

[teslacoils]

6t of 13 percent milling wheat off 130kg nitrogen is good.

Actually you're correct , I hate kg's
So is my agro's maths wrong with this calc .... 260kg/ha Nitrogen (208units/acre) for a 10tonne crop

Bang it all on then.

315 Euros buys you 460 kg N (46%) at 68.5 cents/kg N. 290 Euros buys you 345 kg N (34.5%) for 84.1 cents/kg N, making urea a better buy.

Am I having brain fade ?

300kg / ha is 240 units / acre = 5.21 cwt urea
