Monroe City, MO | My local Coop just bought a high clearance fertilizer spreader for top dressing corn. I would use treated urea. Anyone have any experience and any results compared to injecting NH3 or UAN? |

Paxton, IL | we've got one farm where the farm manager wants to top dress some urea. The farm is mostly 28% and supposed to get an application of urea later in the season. We did it last year, but that wasn't a year to draw any conclusions. Trying it again this year and hope to have some good data for comparison. |

North Central MN | since we are very sandy, that is all we do. also, our growing season is so short (80-90 day corn max) we do not use treated urea or esn as it doesnt release fast enough. actually spread twice, one around v5 and then again when the corn is right at the spreader axles. works really well. |

Summit County, Ohio | we are trying it today, using Urea, with Agrotain ultra. This is my first time with it, we have been dribbling on our N in the past. Our ag supplier bought a new JD 4940 with a ag leader dry box. It sure is a lot faster than using the dribble tubes. As for better I will have to wait and see how things turn out. |

Hopefully, it's an airflow and not a spinner spreader . . ...
Spinner spreaders are not as accurate as an airflow, especially opening up a field (edges) and in windy conditons.
If the field is rought, the spreader bounceing up and down affects the spread pattern.
Lot'ta Urea is applyed by spinner or airflow box on high clearance machines. Urea needs rain (reguardless if it has agratain or other inhibitor treatment on it) to get it moved into the soil.
My opinion, for the price of the inhibitor treatment, just spend the money on extra Urea or consider some AMS or all AMS. Time it for a rain (pretty easy in our current pattern, here) and it's the best bang for the buck.
Keep in mind, you can cultivate it in after it's applyed . . . . . |

Michigan | Would much rather inject uan. It's impossible to get a spread patern as consistant as injecting or dribbling. |
|
| |
|
| Agrotain is not gonna keep it from releasing only going in the air. Applying urea without it and without irrigation is not too bright. |

Grabill, Indiana | I believe that was part of the thought process that Soil Life talked about here on NAT.

NW IL | I'm experimenting with ams and urea. Hope to know more this fall.

McLeod County, MN | I spread it. This year I used 100lb of Urea and 50 AMS. Wouldnt think of spreading without Agrotain. I think I paid like $3 an acre for the Agrotain. It works awesome if you ask me. Nothing but good results the three years I have done it. As far as the pattern, consitancy, blah blah blah, its N. It moves pretty freely through the soil. The sulfer does too. No need to get it down to an exact ounce per square foot. You can miss by several feet and never know the difference.
In my area its real easy to hook a rain.
Have a neighbor that did 225 actual NH3 on some soy ground last fall and I did 180 total in COC with the above topdress. We planted the same day and mine is twice as green as his. You will get a little burn, but it doesnt effect it at all. For all the extra time and money no way would I consider NH3, 28 or 32. Save some of your N for an in season application, it will pay for itself and to have to coop do the application. The bigger the field the better job they can do if you ask me. Some of your smaller non-square fields can get a little beat up. Worth more than fungicide if you ask me.

| My tenant has and also has injected 32%. Just depends for him on the cost of N.

North Central MN | For starters, I was not referring to agrotain, I was talking about ESN. Used agrotain one time and will never do it again, made a mess. Second, I never stated we did or did not irrigate and yes, we do. |
|

|
North Central MN | +1 on the spinners, and everything else you said. |
|
| |
|
| Well that makes lots of sense if you irrigation and you said esn or treated urea. Usually treated means Agrotain or nutriaphere. If you can irrigate I would use straigh urea too |
|
| |
|
angelica, ny | Do it every year, add agrotain to it. Fast and simple. |

Sibley county Minesota | One farmer in my area was planning to do 5000 acres with encapselated urea, not sure he got done with the big rains we received.

Dodge County, WI | If the coop can show you a pan test of their spreader, you will see that it is every bit as accurate as an airflow. The local dealer did one and it was impressive how at the edge of the pattern the amount of pellets dropped off immediately. And the pattern inside was perfect. The newer spreaders are a lot better than the buggy you used to get from the coop.

Amherst WI | I agree but it still takes a good operator to set the gate and spinner speed rig according to what products are being spread.
Ruzobeans and I bought our own Terragator this spring and the pan test showed us it could be extremely accurate if set correctly. We even had a 10-15 mph wind the day we did it. |

SE SD | I did it last year, 120-60-40 urea, DAP, and potash on part of a field that got screwed up and had no fertilizer before planting. It turned out to be about the best corn I had come fall.
I thought I'd try more this year, so Friday I put out 130 pounds of urea with 50 pounds of AMS on one field. I planned to put agrotain with it but when I went to the fertilizer plant with the spreader my agronomist was there and informed me our area was just placed under a flash flood watch so I didn't bother with the agrotain. By yesterday morning we picked up 2.25" of rain so it worked out well for me. If there isn't rain in the forecast I would definitely use the agrotain unless you plan on cultivating it in.
As others have said there will be some leaf burn but it won't hurt the yield. The spreader I used has a 50' spread pattern. It runs down a lot less corn on the ends vs. a 28% applicator. |

NWPA | Yup work good. Maybe some AMS if u can use the sulfur and depending money wise. I think the little burn you may get just makes the corn mad and grow better or maybe its just the nitrogen:-) .

Marianna Arkansas | That the way 90% of it is done here. |

SW WI | Grow some winter wheat and use a spreader...then you will see how inaccurate they can be. We dont spread amything anymore. Inject or air flow. |
|
| |
|
| are they tandem or single axle spreaders. |
|
| |
|
central - east central Minnesota - | mick - 6/25/2013 06:24 are they tandem or single axle spreaders.
Around here, the pull types are available either way - Tandem (holds more) and Single axle . . . . Spinners and Airflow.
The high clearance self propelled (sprayer chassies) are simply the box on the sprayer chassies |

What did you do to make a mess? I've been using Agrotain ever since it came out and have never had a "mess", I spread all of mine with a Wilmar buggy on 30' centers. |

Humeston, IA | Just had 100# urea with Agrotain applied over the weekend to 200 acres. The coop used a tractor and high-clearance pull-type single axle spreader. Rain came right after, so the Agrotain may not have been necessary, but just as well, as the weather has been unpredictable. This application is on top of 150 lbs N as NH3 applied 5/1. We have severe denitrification on our waterlogged soils, I'm afraid.
First year doing this, so I'm interested in the results. My "eyeball analysis" is that the corn looks greener after 3 days, but maybe that's wishful thinking. |

|
| Totally agree especially in the hills. Every checked an airflow on a sidehill that's rough? Good well calibrated spinner will beat it. |
|
| |
|
just a tish NE of central ND | I always thought you weren't supposed to spread urea on corn because the urea burns holes in the whorl of the corn and damages the plants? |
|
| |
|
| It can do that, but the damage usually isn't severe.

Northeast Louisiana | We do it alot down south. Usually by air when we can't get in the fields. We also usually topdress with another 100 lbs of urea by air around tassel. This has shown to give a yield bump around here. |

You do realize, airflows need to be calabratred as well as spinners . . . . to make a brash statement, that a well calibrated spinner will beat a well calabrated airflow ? Come on now ~
The all/both require calibrateing and continues checking to ensure they stay in tolerance.
Edit: on a side note: It's never a waste of time, to want to teach or share experence with those that don't know it all or have had different experences -

| Problem is this...hard to calibrate machine to push or pull product as with a boom in hills. Airflows work fine in the flat ground but with the new spinners will be more consistent over a long period of time in a wider range of environments. This comes from personal experience and also talking with people at the factory. also much harder to keep a boom in this range and it good operating shape for the long haul after many acres, which is the reason why most are junk or trading after a year or two.
attached link on Urea and volitilation...with conditions like last week can pay in as little as two days. Three bucks an acre cost doesn't take much to save or you cannot buy much extra for that.

most do not understand what a morning dew and heat can do....it doesn't melt into the ground it melts into the air and is gone. June is a terrible month to put untreated urea on the ground.

west central wisconsin | He also might have meant treated with instinct. Irrigated sand treated with urea is most commonly treated to keep from leaching, not volatizing. Agrotain keeps it from evaporating, instinct keeps it from leaching. We always side dress with urea on dryland that has been treated with agrotain, because it is supposed to help when it is humid and warm, whether it works, that is very hard to determine. The science behind it is good. |

Central Illinois | We top dressed urea with agrotain last year and saw a 20 bu increase over applying 28% with preplant chems. This year we used ESN, from the comments on here it may be a poor choice. We received 1.3" rain 2 days after applying. Ours was applied with a high clearance air flow spreader. |

ecpa | I bought my Metal Spin Spreader at Central Tractor (now tractor supply) some 15 yrs ago. I added 20inches of metal wall on the top and carry 1500 lbs urea. I have been spreading this way since then. Works good for me. If I was a bigger farmer then I would use a bigger spreader. Don't worry about the burn. |

Anyone top dress corn with urea??
