Nitrogen in seed bed

[Hobkin ground]

How much nitrogen in seed bed for spring barley?
In units per acre please so I can understand it!!

Half of what you intend for the crop, then the balance as soon as you can see the tramlines is what we’ve always done.

very late now though. I was advised for the oats to put it all in the seedbed, 110kg/ha for them. RB209 says something like 160kg/ha for spring barley I think, but depends on SNS (previous crop soil type etc).

We are still just putting 20 units on at establishment and balance as soon as tramlines visible.

Not really late up here yet.

How much N can a seed use, I ask this because if it rains heavy it will go below root depth and it's gone.

 

[Zippy768]

Surely a plant can only use so many units per day. So why the hurry to put it all in seed bed? Could still be split

Worry if it comes dry it’ll not get washed in..

 

[J 1177]

Done 60 units in seed bed and 60 units when trams come up befor

That would be my only concern.
Usually split the dose, seedbed and then tramlines visible.
Drilled some yesterday, for one reason and another, won't get fert til Monday. Looking showery so might stick the whole lot on.
I suppose it being later drilled, one has a much smaller window to "hope" for rain when spreading 2nd split

If it comes dry on late drilled Spring Barley, it's probably better to save the second dose.

 

[Zippy768]

Tbh, I don't have autosteer, so relie on following a light bar for seedbed N.
Splitting means I'll have less chance of misses!!

If it comes dry will it be taken up even if it's in the seed bed, given that it has to be carried in water to the plant.

It’s nearly May.
Put it all in the seedbed, especially if urea.

 

[T Hectares]

If growing for malting then definitely all on asap
Doesn’t really matter if split half and half, just get the second half on quickly and before rain if possible

We finished today on Barley sown last week just before 5 mm this afternoon

The only thing with this approach is the problems I had last year.
Basically had intended to put another 50 units N on at tillering as usual; but we had that long lasting drought which made it pointless putting on more N, and by the time rain was forecast the stuff was almost out in head at about a foot tall.

Worst winter barley crops we ever had last year! Glad I’ve stopped growing the stuff!
Bad enough at only £150 a tonne even if you get a decent crop………..

Same here, but at least you’ll have saved some of your fert cost. I doubt it would have yielded more if you had put it on, in the absence of moisture.

I applied all of my Winter Barley N in one hit last weekend, as the first time I could travel without digging ruts. It was at a lower level than I would normally apply as I have a sneaking suspicion yield might already be compromised.

92 units/ ac .ho ho

Get it all in the seed bed. It’s been wet for so long I believe,sods law it will turn dry and you won’t have the rain to wash it in. Being wet for a prolonged period will have depleted any residual N making the crop hungry from the start.
I know it’s a different country but I’ve tried split applications on cereals and every time would be better with everything in the ground. The short season from now won’t give you as many chances to catch the rain.

 

[Chae1]

Drought starts next week.

 

[Romeogolf]

130units in the seed bed yesterday, drilled a week ago. Light rain now and for the week ahead, need it to fly out the ground. Would normally split dose but too late for that now in my opinion, get it on and get it growing.
