#Urea or uan for wheat ag talk plus#

Just saying over the years what I've experienced. Not about to argue against Needham or anyone else, I'm sure no expert. urea and just haven't seen those yield differences. I haven't done side by side in the same field tests, but have done farm against farm where sprayed 28% vs. Posted 10:34 (#5847778 - in reply to #5847503) Subject: RE: First Time Spraying UAN on Winter Wheat - Any Advice? Why take a 4-10+ bushel hit on yield? We run 28% for the February application (prevents salting out ) and 32% for the second application. It will definitely pay you to make separate trips with N and herbicide. Put a herbicide in the mix and it only gets worse. If you spray, either one will give you a yield hit. If you stream the nitrogen, there should be no difference between 28% and 32%. Haven't ever been able to notice difference. Have run urea followed by second pass spraying herbicide only. It's in need hams srw wheat production guide.

Spray diesel on everything metal before if you're worried about booms and such rusting. But, it keeps you from having to do it all at once 6 weeks before it really needs it. Let's you skimp on the stuff that already has enough tillers but still keep it green and forming a good spike or give a little extra to a thin stand to get it to tiller. I think splitting the N application in two usually pays. I think UAN is a good time to add Zn as ammoniated zinc. Don't let 32-0-0 sit over through low 20's weather without watering it down or it'll salt out and plug stuff. Right or wrong I never rinse and get 5+ years out of pumps and usually can repair them.

Here they have us use 28% because they claim 32% will burn the wheat. Posted 17:10 (#5846468 - in reply to #5846401) Subject: RE: First Time Spraying UAN on Winter Wheat - Any Advice? Try to avoid streaming when it is too windy Not that it is wrong, but I don't know anyone that rinses daily. Posted 16:46 (#5846438 - in reply to #5846401) Subject: RE: First Time Spraying UAN on Winter Wheat - Any Advice? I have been told I should rinse the entire system every day after spraying as the UAN is very hard on the cast housing of the pump. I will be using streamers and won't be applying any chemical with the product. I am spraying 32%-UAN on my winter wheat with my own SP Sprayer this year and was wondering if anyone had any lessons learned, good advice, etc. Posted 16:14 (#5846401) Subject: First Time Spraying UAN on Winter Wheat - Any Advice?
