Wondering how much liquid fertilizer I can put down 2x2 planting corn.
Thinking about 70 to 100lbs N. 30lbs P. 40lbs, S
Have never done it before, so I'm not sure.

I'm not sure how you can get to those numbers and physically get the gallons through the system? You will be filling at each end. I've done 45gal/a of 10-34-0 + micro's without problem.

I was thinking the same thing davro. In 2009, I accidently put down 380# of dry 15-11-24-5 in 2X2 on 30 acres and my agronomist was worried I my burn the corn. It worked and I got pretty darn nice corn! I would ask an agronomist first.

With $6.00 corn, I want to put down a little extra myself this year.

Low end it would be 36 gal/ac, high end would be 47 gal/ac.

10-34-0, ATS, and 28% would make up this mix

70-30-0-40 would be 8 gal of 10-34-0, 14 gal of ATS, and 14 gal of 28%

100-30-0-40 would need 11 gal more of 28%

With a 2000 gal pull behind tank, you could get 55 ac/fill on the 36 gal/ac rate, and 42 ac/fill on the 47 gal/ac rate.

This would be possible, but depending on the soils the N rate might be a tad high along with the sulfur.

If both were cut in half, it might be easier to sleep at night?

Uneducated response from here,,,,, I am going to say you are a little heavy on the N for 2x2 placement, of course I don't know your soils like you do. Once again same with the S, Here I apply 25-26# acre is about max, don't think it will hurt anything, just the crop shouldn't need that big a shot at one time or one season, 'course like I said,,, I don't know your soils like you do.

This shared info is just that, shared info and nuthin to live by............

Western EC Iowa

5 gallons of thio split on each side of the row OK along with 10 gallons 28%?  Planning a 'sidedress' pass before planting to get the 28 and S on.  Going to set up a sidedress rig with coulters 3-4 inches off center on both sides of the row and 'fluff' the strips a little, so it could potentially be right in the row, but should be off the row at least a couple inches.  Thanks, Ben

neat idea Sam's Dad, but I would be concerned about planter drift landing corn row in salty spot.

Sidedress drift should be similar to planter drift. I think. If we don't like it, we can move them out a little. Would 5 gpa 28 be too much in furrow?

We've been spreading a dry mix of 100N/with Agrotain 30P 30K 40S preplant, and I feel we're not getting the full benefits out of it.
This is irrigated ground, very sandy.
Just wondering if we can replace the dry with a 2x2 liquid.
We can cut r N. down to 60lbs and add more thru the water later.
Thanks for your replies

Subject: Irrigated + sandy = Split app of N


EC MN - Hour North of 'The Cities'
If I had an irrigator I'd try to split that N up more than twice...

I don't know what your growing season is like, but around this area, if you're sandy and irrigate, chances are you're sidedressing and maybe doing some fertigation.

Might look at splittin that S up as well if you're goin that heavy. I think the highest rec I've seen for S in a band is 15 lbs.

I'm going to put 52 gallon of 32% on top, 4-5" from the row with Agrowtain plus. Thoughts?

Subject: Can you get it in the ground?


EC MN - Hour North of 'The Cities'
If you can it'll be worth it unless you can time a rain or irrigate afterward.

How much is agrotain these days on a pre acre cost? Might pay for some coulters in a heck of a hurry...

What type of soil? Can it hold that much in one shot?

I believe the rule of thumb is 10 gal of liquid N X inches away from the row that most abide by.

is too much.

As far as drift is concerned, if I'm reading correctly, 2 coulters/row will be used ahead of the planter. That has twice the "anchoring" effect minimizing drift of the implement in comparison to the planter.

With a good RTK setup, that will be somewhat minimized or if you have minimal amount of acres with any degree of slope to them.

My opinion only, but that setup is kind of like taking a semi down an icy mountain road. You can go down too slow 1,000 times.... you go down too fast only once.

what is your cec? that will have alot to do with the "holding capacity" of your soil use your cec X 10 and I would not put more than that on at any one time N is hard enough to keep where we want without over loading the "holding Capacity" of the soil. Well that is my two cents I am sure not all agree with me but I use better safe than sorry at my farm

We've never used it...just dry here (AMS).

I know I've priced out a liquid program before we went with the dry, but it was fall of 09.

take the amount in lbs of N plus K2O and if it doesn't add up over 100lbs/acre you are ok

Subject: N + K2O < 100 Rule


EC MN - Hour North of 'The Cities'
I've heard this many times, but does it apply to all CEC values?

What about soil moisture levels?

I would think the salt load might be a bigger determining factor, but I'm still searching for insight on this one.


Lookin for answers...

You listed all liquid options. I guess that's why I asked about the ATS. As I recall, ATS was a lot higher than AMS on a per lb basis.
