Urea Application /w Late Herbicide in HRS Wheat

That is a big part of it, SF3. We are not Europe or in a soft winter wheat zone of the US. Our practices are going to reflect that. Now, not saying don't try it. But we do not have 150 to 170 days and consistent growing conditions to get those wild yields.

Agree 100 percent with the last 3 posts. top dressing is a timing nightmare it will cost you big time on a year when you cant get your timing right. Seeding is by far the most efficient time to apply all your fert but you need to be set up for it.

Depends on the type of top dressing - time it with herbicide and fungicide - no time lost and you are out there anyway. There is a benifit in alot of situations. Reduced herbicide damage on crop and increased weed control are two we seen this year, plus yeild and small protien gains in most cases .
All are correct on growing season here and abroad, it is short here and time restrictive as is the optimum seeding window - a lot of feed / frozen wheat here from late seeding . Probably 50% to do with weather and 50% to do with time management . Top dressing can help with the later 50%

I dont see how you can put a significant amount of nutrient on with fungicide or herbicide without leaf burn.

[Hopperbin]

Reduced herbicide damage on crop and better weed control does not sound fitting. Would think one does not go in hand with the other. A lot of chemicals are not registered with fert application. Which chemicals did you have in mind with your fertillizer klause?

[Klause]

We are talking 6 to 10 lbs an ac. Not a significant amount. Keep in mind chemistries play a big roll... Some chems, Bassa gran comes to mind, use 2800 as a safener and surfactant.

to me you want to provide nutrients to plants through roots its the way they have evolved for billions of years.

[Hopperbin]

I see use of fertilizer mixes is not recommended for mixes with most crops under western canadian environmental conditions with basagran. Says so in 2014 guide to crop protection. Says amonium sulphate may improve weed controle in dry beans but may damage crop also under humid conditions. And never the forte with the built in adjuvant. You were refering to wheat. So its not on label.

[Hopperbin]

Isnt after seed timing of n be supposed to be put on in a dribble band?

[bgmb]

Thats what i thought too hopper, I think they r talking about foliar applications of small diluted amounts. Might be worth a try but i have my doubts. Nitrogen is always readily available in the soil so better to have plants get it through their roots.

[Klause]

Hopper we put s on with Bassa gran/viper.


"Humid" and "western canada" aren't the same... it gets real hot in Manitoba where you spray in 30 degree heat and humidity up to 90%...


I'm not sure if the guide lists it but when you purchase it you get 2800 in jugs with it

I e with Viper you need 2 jugs of 28 for 1 jug of basagran.


All about the chemistries.


N isn't as available as one thinks... it leaches out of the root zone. It is lost to the atmosphere in hot wet conditions.



Generally top dressing is done with streamers yes.



I'll tell ya one thing... we have a couple of guys that tried top dressing this year. They have all told us / booked their whole farm for next year.

3 gal of Slow release liquid foliar (6 lt at herb and 6 lt at fungicide) gave the same results as 10 gal 28-0-0 dribble band in a separate pass. Timming is right at applying N and other nutrients at 3-5 leaf (herbicide time) and late boot /early heading (fungicide) in wheat - no extra pass and zero leaf burn with extremely low salt 28-0-0 Kugler XRN. Anyone at our tour seen the weed control aspect in canola plain as day in the plots (Ado was there - saskcanfarmer says he was)
