Urea Disolved in Water and Sprayed

Fergienewbee · Jun 13, 2013

I have a 30 gallon spray rig with a boom. Can I dissolve 0-0-46 in water and spray my corn? I would plan to spray between the rows @ 26". How much would you dissolve if it's okay? One plot is 1/3 acre the other 5/8 acre. I should have just spread it last night and let the rain do the rest.

You are going to need pretty good size nozzles to get it to spray. If I remember my fertilizers, I think you need to end up at 26%. I thought I could do the math for you, but I for got how. Sorry.

You maybe able to get it to dissolve but I think you will still have too much salt/dirt in it to run trough a sprayer. I would just go buy some 28% nitrogen if you want to apply it with the sprayer.

What I have seen guys do for smaller plot is just take an old sprinkler can. The old ones that the sprinkler head will come off of the can base. Then fill it with fertilizer and run it along the row of corn. If the fertilizer is good and dry it will come out easily. You just need to weight the can ans see how much it hold and then figure out how many feet in each row it should cover. This way you kind of control the application rate. The nice thing is that it is simple and you can easily put more where the corn is not quite as good.

Then just cultivate the corn after you have your fertilizer on.

You're really asking for lots of plugged up nozzles. "I think" all dry fertilizers utilize a "carrier" that does not disolve very well. By the way, urea is 46-0-0. I think for no more acreage than you're doing, I'd broadcast dry fertilizer, even if by a hand held applicator.

I don't think it will dissolve very well. And I think you will burn the corn if you don't use drops to get below the canopy. I'd spread dry somehow.

Thanks for all the input everyone. I'll do the dry fert. We don't learn anything if we don't ask.

You can dissolve Urea for spraying but it requires a lot of agitation. When I worked in lawncare we would use it to spray on lawns but we had a trolling motor in the tank to keep it constantly moving. Also a nozzle used in lawn spraying(wand) has larger holes than a regular insecticide or herbicide sprayer that is used for liquid chemicals.

My corn started fertilizer is desolved dry and I do not/cannot run it through a sprayer as it will plug the nozzles--too much solids left behind in the process. So for left over started, which I use for lawn fertliizer, I have an old sprayer which I replaced the nozzles with a flat plate about 1 1/2 inches below the opening. This causes the stream to spread into a cone which dilutes the strenght enough to prevent burning.

Those spreaders for ATV's work very well for that.

I hope you meant 46-0-0 not 0-0-46. As the 0-0-46 is super K and will not dissolve. 46-0-0 will work in any sprayer with any nozzles if you dissolve it before adding to the main tank. If you just dump it in it will plug everything. I have sprayed dissolved urea too many times to count, used to do this bi-weekly to spoon feed golf greens. These were tank mixes that could be with fungicides, insecticides, micro nutrients, or wetting agents. Best dissolved in a mixing cone but my sprayers had a screen basket in the fill opening. We placed the fertilizer in the basket and used a hose or the hand gun to dissolve it into the tank already half full and agitating. Anything that won't dissolve through the screen doesn't go in the tank. Did this for almost 20 years and never plugged a nozzle, we even did this with U-Max and U-Flex controlled release Urea.
