Spraying fertilizer

[Reid1650]

Would this be an ok way to put fertilizer down like liquid nitrogen?? Is there any other form of fertilizer you can put down in liquid form?

Local elevator had a side-line selling liquid fertlizer; he would spread it or you could rent his pull-behind rigs. He's now out of business, but he could mix any formula you wanted; just like the dry mix boys...........

my brother use to custom mix liquid fertlize and he had to be careful of the temperature because it would salt out as he called it and wouldn't spray out of the nozzles.

It works with 28 or 32% N, also there's a 10-34-0 and many proprietary mixes around 9-18-9, some with sulfur plain or in the form of thiosulfate. You do have to watch out about mixes salting out at low temperatures or high concentrations, and most last best when worked into the ground, especially the 28 and 32% N ought to be incorporated in a few days or else rained in.

Most feel better about incorporating the fertilizer right after spraying it on if there is any N involved.

It is difficult but not impossible to mix all 3 - N,P,K - into one liquid spray. Need to talk to your supplier about that.

Volume. If this is the only N you are using, you need to apply a lot of gallons per acre. Typically folks do this for about 10-20 gallons of 28% along with a pre-herbicide spray, and so get what, about 30 - 35 lbs of N applied this way. If you need 120 lbs of N applied for corn, you will need different nozzles or sidedress with something else.

Its probably THE most expensive way to fertilize. While fertilizer is expensive in a dry form, dont ever forget that buying it in solution means you are buying water, for way more than it costs.

I fell for it last year, and bought the foliar feeding stuff, but on a per pound basis I was sick when I figured out how much I had spent.

Right now, as of today, Woodford Feed had urea for 400 a ton, DAP for 500 and change, and muriate of potash for 850. If its for forage and you can wait on it, they told me to look for muriate to drop 50 bucks a month from now until August.

I used to put 28% on with my treflan setup just used bigger flood jets and it worked fine. The problem you are going to have, if you want to put all your NPK on with a sprayer, is that the mixture the commercial elevators make is a suspension not a solution. It will tend to settle out and plug your nozzles. The liquid starters are a solution and don't have this problem. But to put all of your nutrient needs on this way would probably be cost prohibitive.

15 gallons of 32% is 53 pounds of N. 15 gallons of 28% would be 44.5 pounds of N.

I put a little more than that down with the planter in 2007. Ended up with 60 pounds of N from the 32% because I drove slower than I should have. So I put 17 gallons to the acre.
