nitrogen application

[Clive]

I tend to go early with my N. All done and dusted on all crops 10 days ago (yorkshire).

Am I correct in thinking that @warksfarmer tends to use lower/cheaper fungicide programmes?

If early N produces thick canopies which creates somewhere for fungal growth to proliferate, up to now it has maybe been OK because fungicides have been effective.

BUT, if fingicide efficacy reduces, then maybe I may need to re-evaluate what I do in future. Shifting from large early doses to something more like warksfarmer's programme might be the way to go.

I won't like making this change, as I feel that building lots of biomass early helps on my drought prone soils. But I may need to change in the future.

I think you are spot on if you have drought prone soils - build biomass while you have moisture to do so

Looking at N timing advice further south in Europe where water restricts yield they take the same approach

Mine was all on before this last few mm of rain

We nearly did the same but as crop was stressed I think we would have just Scorched it badly with liquid

We have a bit of rain forecast mid week and soil is dam / seed enough here after last week to get it in I think

Certainly glad it is all been on here a fortnight, it is a classic year when you could be left looking at starving crops and fert granules laid on the top in dust, if fert was applied at the "proper" time.

Last low dose on the milling wheat today, hopeful of some rain later in the week.

 

[Brisel]

Last of the N on wheat going on from tomorrow. I've been loath to apply liquid in the high winds recently as they have dewaxed the leaves & I've got leaf 2 appearing and really don't like scorching yield building leaves I've just spent money on keeping disease out of!

Mine was all on last week as well. After over 30 mm of rain since Friday, it had its T1 today, and looks full of potential . A bit too well if I’m honest. Robust growth reg went on today.

The going heavy with N early may not be the optimum approach for people in the South West where moisture is rarely an issue. Dumping a lot of N on into crops that look pretty angry to begin with is going to result in dense, leggy and very lush crops which is a hot bed for disease and lodging before you start. The old hands always said the last dose of N all wants to be on before the flag is fully out but I agree you have to farm what you are looking at and ignore the calendar.

All done here ahead of - hopefully - rain weds and thurs

How far away is T2 do you reckon?

 

[Zippy768]

End of next week wouldn't be far off

So actually not that different from the usual schedule.

Gravity after potatoes . Mine pretty much all looks a bit lush, even the continuous wheat.
It could probably stand another hot summer!

I recall a time when advice was to let it go the colour of yellow pages before n1

I also have seen advice from same people (Yara) to build early biomass

........... who knows !

 

[B'o'B]

Nitrogen is a pretty blunt instrument for crop management and wheat and OSR are pretty forgiving plants in how they build yield.
Here over the last few years application date has had very little relationship to the date the N is taken up by the plants!

Well, those spuds did a great job of robbing your dirt of nutrients, didn't they?

Yes, and ruined the soil for years.
Went through with a discerator, then combi drilled. To be fair, there’s only a few of my fields I’ll let potatoes be grown on. It’s got to be the right soil and no drains.

Gosh that’s early. T2 here, would be last week of May normally.

It will be a little early for us to, usually trying to silage and t2 at the same time. T1 went on Easter weekend, so will be looking at almost 3 weeks

Last n going on leaf 2 90 % we're 4 days earlya than last year crops look short at the moment and a nice colour not dark . but very dark green crops all around here with every ones wheat looking v good. Didn't get the quantity of rain they forecast but enough to last a week or 2
Scorched the crap out of 50 acres in the bright sun t1 but looks like it's getting over it.
