Liquid fertilizer

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

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 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 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 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.

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 biggest complaint with them is they are designed for guys that apply big rates not guys that are just looking to top up N if weather permits. I didn't like having to go faster just to apply 25 actual ********** claims on his site that they produce streams not droplets and that means less crop damage but that's not what I found. They stream for a few inches below the bar and then break up into droplets. I had pretty bad burning on canola because the drops hit the leaf and roll down to the stem.

I use JD 6 hole now and don't see any difference between them and the stream bars. Less sensitive to boom height than a 3 hole and I can cradle the boom now. Smaller orifice than the stream bar's lowest setting so I don't have to go fast to put on a low rate. Makes doing prescription applications easier that way.

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.

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.

I've played around with N apps since the early 00s and I can't find any rhyme or reason to a response. I've done tissue tests that show high N levels so I don't apply and get low protein. I've also applied to high tissue levels and got a response to yield and protein. And the opposite has happened too. I've had 3% lower yield due to wheel tracks. Mid season N is a crap shoot where we are.

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 40-50 pounds with the drill and add a top up, can be stressful trying to get over all the acres before a rain but not too early to loose any to gassing off, agrotain would help but also added cost as well
