I think dry would be a great idea, are you strip tilling or anything ahead of the planter to put more nutrients in place or planning on a later side dress. Even in milo you'd be minimal at best with dry going down efficiently with a planter...unless your pulling some kind of dry cart. But for a pre plant, I think it'd work...have actually considered this on our farm.
Plus in this area Dry is about 66% to 75% cheaper then liquid currently.
I was thinking of outfitting my planter with a dry fertilizer box, with dics application located 2inches to the side and 2inches under the seed placement. I read in University studies that 2X2 method has had the best return. Strip Tilling or some type fertilizer banding machine would be great, but I am trying to strictly no-till, and I figured a simple dry fertilizer component added to my planter will be the cheapest.
I plan on side dressing later with liquid, but my cation exchange on my soil tests are relativly low, usually in the 2.5-4.0 range, so I am planning on spoon feeding the corn crop, Thats why, I am interested in getting some sort of fertilizer early in the ground.
But you don't think that the dry with the planter will be effiecient? In what way? Uniform Rate? Haven't grown Corn before.
If your doing it with a dry box that can hold quite a bit then you'll be alright. We are considering using the insecticide boxes already on the planter and putting down a low rate of Map as we're planting, probably dropping right behind the seed ahead of the press wheels. The reason I claimed inefficiency is that in that kind of setup we'd be filling up every 40 acres or so. With a bigger box, one might be able to efficiently do it. We'll strip till ahead though also.
What sort of dry are you putting down, I don't know about phosphorus and other fertilizers, but Agrium/CPS has ESN, which is encapsulated Nitrogen that breaks down over the life cycle of the crop...essentially spoon feeding as your talking. If you could put enough of that down at planting, it could save you another pass across the field.
ooo yes I have thought about useing the insecticide boxes too, However afraid of seedling damage by putting it directly with the seed or is that only to worry about liquid?
I am not sure which fertilizer product to go with, Who is the provider or Agrium?
A full crop rate of fertilizer would be too much right beside the seed, with liquid for sure. I'm not sure on dry, we put down a whole supply of nitrogen and phos beside wheat and it doesn't hurt it..actually helps it, I don't know what effect it might have on corn.
Crop Production Services is the company name out here, my Dad is a salesman for them. Agrium is the parent company. I know CPS is a nationwide company, I know their in Florida, North Carolina as well as the entire plains but not sure about where you are. Farmland (Co-ops) are getting an encapsulated product now too, a little less quality but the encap products are branching out anyway.

I do think that the liquid would be more likely to leach or at least leach more quickly. Here's my logic: Leaching is the process of a substance (whether it be fertilizer or chemical) moving through the soil. Moisture (rain) is what pushes it through. The dry fertilizer would have to "melt" into a liquid form prior to being able to leach. Therefore it would stay in the soil longer than the fertilizer already in the liquid form.
