We are looking at putting liquid fertilizer on with are sprayer. What is the best sprayer bar or nozzle to us
And the best spray.
Going to be applying to wheat and canola just as a top up if we get the rain this year .

We are the same, if it’s wet after seeding i think it definitely helps, I’m not great with trials so I’m not exactly sure how much yield benefit we actually get vs putting it all down at seeding. Biggest reason for us is that we can’t put enough nitrogen on with the drill we have, Dutch spur opener on 12” spacing, dry years we have issues with ammonia toxicity so we try to keep it down around 40-5...
Over the last 20 years or so, I've used 3 hole Teejet, Chafer's variable orifice stream bars and now 6 hole JD tips.
3 hole are too dependent on boom height. Too high and they overlap, too low and they streak.
Chafers stream bars are good but make sure when you cradle your boom that none of them will be damaged. There's one spot on my Deere sprayer where the hand rail hits a streamer. My bigge...

I honestly think it's splitting hairs. You get some burn regardless of what you apply it with. If you concentrate the same rate from 6 to 3 streams it's logical you get more burn but I don't think it's twice as much from what I've seen.
I've seen zero yield response to application and I've seen 1 bushel from every 2lbs of N applied. Weather plays more of a role in response than the tip does.

Did you notice any difference in plant burn going from 3 stream to 6? My agronomist was concerned I would see more. Always curious how it worked. In some of the heavy clay we farm I thought coverage would be important instead of waiting for the N to move and even out.

We use the adjustable orifice version. I if you go with the stream bars I would recommend them over using the separate orifice disc. We use 28% nitrogen with sulfur added with a good stabilizer.

I top dress wheat and canola with a blend of 35-0-0-8, works really good if u can time it before a rain. Use white tee jet 3 hole nozzles run about 12-14 gallons at 12mph. You can order them from any dealer that sells teejet or pattison liquid systems In Lemberg SK sells all kinds of stuff for liquid fertilizer. Tips are cheaper, stream bars are better just depends what you want to spend

We use Chafer stream bars when top dressing wheat. They are better than any of the stream caps. Not affected by wind or boom height like the stream caps. Take a look a Needham Ag website. A lot of good info.

I use the trip stream nozzles as well on a rogator 1100

Where are some of the better places to get your liquid fertilizer my local co-op doesn't deal with it a lot

We use tri stream nozzles. What model of sprayer is this on?
