Anyone out with N

[Feldspar]

Barley at the moment. A bit yellow. Mildew more of a concern although hope frosts will have sorted this out a bit.

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!

Is ground not frozen with you?

Didn't freeze for more than 12 hours in the last 24h. Checked before I went to bed last night. I've seen spring barley with 2cm roots on it drilled about 14 days ago. Soil was warm enough that things were moving.

The snow will wash it into the river before plants can take it up.... 5C max air temps here for the next 2 weeks, crop is going to be going nowhere fast now the temperatures have dropped.

I'm not worried about the plants taking it up yet. I am worried about the soil latching onto it and holding it for me until my crops need it (which I admit is not now). As long as it can do this effectively (and no-one yet has explained to me why on my soils it can't, although happy to be tutored), then I am not concerned. If it takes 20 to 45 days to get down to 2.5cm depth, that's fine by me. I do think the basic (is that an unintentional chemistry pun?) differences between different forms of N are just lumped together in too many people's minds.

Which variety of Barley is that please James?

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.

That's interesting, 3 to 6 years for phosphate to move 1 inch !
What else has ammonium N apart from dap ?

AN...............
Half of it anyway..............

last couple of years I have put a few kg of urea on early on DD drilled wheat and I believe it was a benefit, this year everything is a really good colour so in no rush and am away end of next wk till the 10th but if its dry when I get back I will put a bit on, we are almost bound to get some rain at some point and the crop might need it, imvho it would be better to put a bit on dryish soil as urea and let it be absorbed than put it on wet ground when it really needs it and folk get a bit desparate and then a storm wash it away

Does anyone use a bit of foliar N in with the manganese to perk things up and keep them ticking along.

Last week I ran over everything with some MN and i chucked 2kg of urea per ha in the tank aswell. Some of my earlier drilled barley, which has done a lot of growing was starting to go yellow but since I applied it it's greened up and won't take any harm until top dressing time probably around Valentine's day.

Has anyone got any links to research about foliar N?

Snap. Great minds. used AN though.

Foliar nitrogen- in the plant before a ditch...

I just don't see the point of applying something the crop is largely not going to make use of for a time. I think what others have said holds true: time for a winter yet.

In manganese products they are often in the Mn nitrate/sulphate forms so your crop is getting a tiny dose of goodies with it.

Interesting, what rate did you use? I uses AN last year but didn't go too mad as I was worried about scorch.

My mn is the sulphate form, which does green things up but I certainly feel the crops just needed a little N to stop them loosing tillers. I also think the N helps the uptake of the MN because any patches I had have pulled round quick.

The notes I have say 1 kg of foliar N is worth 6 soil applied and There seems to be a lot of gardeners on the web who swear by a 2% N foliar feed to pick up poor stressed plants.

At 150 lt ha water how many kgs of 46% urea do u need for a 2% solution.

 

[Brisel]

150 l/ha is 150 kg. That’s the easy bit. 6.5 kg urea I think.

 

[Flat 10]

I did 3. Can see diff where I didn't use it. I think you need approx 6kg/ha (rough calc in my head) to give a 2% solution

So, sorry if I sound thick here, I know I am. Would you just pit the urea through the induction hopper with the manganese?

Still not going yet but can definitely see the logic of doing this. I think I am seeing the bonus of striving for higher OM and soil fertility across the farm at the moment, saying that everything looks well locally apart from slightly yellowing barley.
