Single Pass Systems are on the way out

[Klause]

Wow... since when does an extra pass mean soil disturbance...


Streaming. .. melting urea and foliar feeding... could be adding 10 lbs of N every time you cover thr field with the sprayer.

Bucket this is not really about growing more for less, it's just splitting fert timing and being less reliant on expensive iron to be more efficient.
Although there may be some good deals at auctions this spring on seeding outfits.
There are many ways to dissect any seeding/fert system, they all work - it's just at what cost?
I look at it from a time and cost management view point. There is only so many pennies in the well and time on the clock regardless of farm size.

Seabass - you don't have to change tillage pratices. You can still be zero till. This has nothing to do with any extra tillage at all.

[furrowtickler]

Klause - are using melted urea with herbicide and fungicides?
What rates are you using to get 10 lbs N ? Any leaf burn issues ?
Have you done trails of melted urea beside dribble banding 28-0-0?
Sorry for the questions but I would like to try doing this but I am nervous about crop burn as a foliar.
So each pass is in that $5-6 /ac range ?

Ya I understand furrow. In our area it is usually wet so having some black dirt showing generally helps. However that being said we have had dry windy springs which make it a helluva lot harder to seed canola. Most times I find if I guess right I look like a genius. Lol
As for urea furrow we have melted it down and applied it with herb and fung. Have to be careful what products your mixing with and how much u are putting down. Found it to be a PITA. Have switched back to 28 dribble banding after herb app. Costs a bit more but more bang for my buck with very little injury. Have experimented with additives in 28 with less risk of antagonism. Still trying to find what works best as every year is different. As for urea it is definitely worth trying as long as u are set up to mix a lot in one shot. Can be a bit time consuming by yourself. Definitely cheaper.

Very recent work by NDSU shows that there is no difference applying once or multiple times. Irrigation or not. Fertigation or not.

So um, ya, bad idea unless you want to support the oil industry.

My best results are generally when the nitrogen gets applied in the ground in one pass with the seeding unit.
In our short season and crazy rains, if you get a chance to get across once, you better get your N down if you can.
If not, the sprayer can dribble it on in a hurry if needed.

Guess we missed the memo to single pass!
Always fertilized in fall, seeded into harrowed stubble. Never spent $$$ on iron, a little black for warm up, usually too wet in spring any way.

[Hopperbin]

What worked last year has x fill in the blank percent chance working this year.

[Oliver88]

Never have done the one-pass system either.

NH3 in a separate pass prior to seeding, either fall or spring time depending.

Who in the hell is going to spend their time "melting" urea so you can spray it on the soil surface. Put your fert in the ground where plants can get it. 100lb of nh3 in the spring, beats top dressing every time and way cheaper than urea.

[Klause]

And you know this, bgmb from trials?


The point of melting urea is to foliar feed. You're not putting it on the ground. You're getting plant uptake.


Urea also helps make chemicals hotter.... try 5lb solution with Liberty. You'll never have to worry about cleavers again.

[bgmb]

So why are we melting urea vs. using 2800? cheaper?

[WiltonRanch]

I really should do some foliar urea to see myself. I was under the impression foliar feeding was like feeding someone with an oatmeal enema.

[Klause]

Urea can be absorbed through the leaves. Ammonia can't. UAN will burn plants way more than liquid urea will...

Have a look at stuff like kugler... then you don't have to do the melting....
