Foliar Urea at 45 l/ha

[Swedeboy]

Anybody with experience spraying 45 l/ha of urea?
Looking at nozzle chart it would mean green 015s at speed.
But what about blockage?

Normally we use 91 l/ha with guardian air 02s which gives us
20 kg of Urea. Now in the followings of Joel Williams we want
to go 10 kg but at the same concentration.

Any thoughts on nozzles?

Water it down a bit to get your normal rate?

Just water it down, if your doing the Joel Williams method you will be adding some more stuff in anyway.
just make the mix so it goes on at your preferred rate

Sorry, I have no advice to give, just curious as to what actual rate / ha of urea you are putting out ?
Also, what is the “Joel Williams” method ?
I met him here in Aus a few years ago & found him very interesting

Thanks for replys.
Yes, it probably makes sense to water it down. It's just I was dreaming of doing
more ha per load..

Joel's 'method' is to make at least me understand how N works in the plant/soil and therefore to be able to maximize the use of N specifically in a foliar context.
This has let us go from AN 180 kg/ha down to 120 kg/ha using predominantly Urea.
Now aiming for 100 kg N and then less... This is in the context of 7 t/ha milling ww.

Joel is one of the rare people able to explain complex issues in a plain way and not
while trying to sell you something. Good advice is to get to know him!

Do you spray it all on using standard nozzles? Do you add anything else to it,eg molasses, humates etc. Have been thinking of trying something similar myself but didn't want to scorch everything.

Plan is in kg N.
60 with dribblebars, mix ammonium sulphate, AN and Urea.
Then Urea for foliar in 10+10+20. The last 20 for protein.
We add molasses, humic and fulvic and whatever else is needed
according to sap analysis.
This is all very new to us but last years results looked very promising.
I would however not be comfortable doing it without 'a hand to hold'.

Last year we did 20 N on each foliar but no scorch. Maybe just luck since I now understand this is pushing it a bit. The additives probably help here.

All in all its a good thing to actually use the nitrogen and not just putting it out.

Who were you using for sap analysis?
