I have never done anything like this but wonder if aeration would help or possibly grinding it. Another thought would be to use UAN 28%. I would think with both urea and uan it is going to burn the leaf because of the salt. I would also wonder if it is just going to evaporate into the air. Once again I have never tried this or have any knowledge to be answering just giving my initial thoughts. What are your thoughts In trying to do this?

The claim is that it is a very efficient form of nitrogen, it gets readily taken up by the plant and is quickly converted to protein in the plant because urea n is tied to carbon. It is supposed to not burn the leaf, but it is also commonly recommended to include humic/fulvic acids, sugars etc. So those things probably help buffer it as well. With no till I have been trying to time my dry urea applications ahead of a rain but I don’t think I have hardly ever gotten it right. Looking for alternatives

Very interesting question as there is alot of discussion about this currently. There are several companies doing this and combining their regen microbial carbon products with the melted urea. Terraganics (Texas) Growth Technologies ( Grand Island, NE) are 2 that come to mind. I can lead you to the process of disolving urea, but the jury is out about what combinations of other compounds to add. The FluidFertilzer.org website has a document discussing the mechanics of disolving urea. Hope this helps.

Hi Leroy, I did some experimenting last year with 28% foliar. I think the urea would be a better choice, but I didn’t want to learn how to melt it before knowing if I wanted to use a foliar N source. I sprayed my wheat twice with 2.5 gallons of 28% plus 6 gallons compost extract, 1 quart molasses, both for nutrients and carbon and enough water to make 20 gallons per acre. I only saw burn where I overlapped. I also sprayed 4 corn fields with the same mix once, (thigh high) the temperature was a little warmer, and I did get burn. Also be aware that the 28% will kill the biology on the plant. This will open up opportunities for disease to set in. So it would be good if you could come back a week later with a compost tea or extract to try to replace the good biology on the plant. Jim
