USA&Belize | Is this even possible? If it works how do you go about doing it. Would like to put it on rice then when we spray for weeds. |

Pulaski, TN | I have been told that you mix Urea and Amonium Nitrate together and add water. Never tried it. |
|

North west MN | We had a guy up here that did it. He used big hot water boilers to melt it and also some NH3 mixed in the water. The product he had was very reasonable and would not burn the crop I would put 10 gallons an acre on and the next day the wheat greened up so much you could see where you left off. I wish someone would start making it again. |

| Urea and NH4NO3 mixed will not make a bomb, check the chem formula. Urea 45% mixed with H2o will give you about 20% Nitrogen, while mixing it will be exothermic( cold) but will not burn foliage. |

Near-north Ontario, French River | 28% or 32% UAN, is just that.. a mix of Urea and Ammonium Nitrate + H20. Instead of trying to build your own, why not just use 28%?? |

So If my I am putting on 10-15 gal of h2o to the acre how much urea

nw NC | You are right about it getting cold. I dissolved some damp and lumpy ammonium nitrate in a barrel of water a couple of years ago just to get rid of it. The outside of the barrel frosted over on a 70 degree day. Put a thermometer in the stuff and it showed 10 degrees F. Should have made some ice cream . |

N FLA | I used to mix it in ground temp water, and would always have crop left in the tank. I was injecting into a pivot. (Pump out of top of tank) So it wasn't much hassle like spraying would be. I suspect you probably can't dissolve much more than 1 lb per gallon. But really wouldn't attempt it without hot water. Not what you want to hear, but I suspect you would have better luck with spray grade ams or calcium nitrate. More $. |

NW iowa | A number of years ago we made 22 percent nitrogen out of water and prilled urea. We heated it with nh3. We used a hot mixer and had mild success breaking the product down. If memory serves me right we heated it to 128-130 degrees and needless to say there was quite a lot of free ammonia. When the season was over there was urea left in the bottom of the tank which was it suprise. So it was better than nothing but not great by any means. |

USA&Belize | Sorry for dumb ?s But w don't have 28% readily available in Belize w don't like spreading dry because it gets wash away with the first rain just trying to us what w have available. dos anyone know what the formula is like how much % 1lbs to1 gal would be would this burn?
We have urea an Ammonium sulfate not sure about the nitrate can w o anything with those. we don't min the pain of melting it:) or so I say???????

NE Colorado | Some years ago our local coop was making a "no burn" solution with urea for topdressing wheat. I liked using it but they no longer do it. When I wanted to make my own they told me I had to use hot water to do it.
I didn't completely understand why until I looked at the list of ingredients for a couple of cold packs I was keeping in my first aid kit in my shop: urea and water. By breaking the seal between the urea compartment and the water compartment in the cold pack, an endothermic reaction gets started and the cold pack gets cold. Then I understood why hot water was necessary. |

Wallis, TX | Add water and stir. You can probably go to about 10 maybe 12% N (1/4 urea, 3/4 water by weight) without heat if you're using 70 degree water and its warm out. With hot water you should be able to go up to 15 or 16%N (1/3 urea, 2/3 water). E-mail in profile if you have questions, or call me tomorrow 979-571-7097 |

Mississippi Delta | You may want to do some checking on applying liquid on rice as a source of N. I was told not to do it, that you will lose the majority of your N due to the flooded environment that rice grows in. Urea is your best form of N for rice I believe.

Scotland | We just use water at ambinet temp and it mixes fine, can get 20%N w/v with Urea only, 23%N 8%S with Urea and Ammonium Sulphate, 33% with Urea and AN, 36% with Urea, AS and AN. I have recipes if you would like them. The urea/as mix and urea alone generally take 18 to 24 hrs to mix a batch, when an is added that time can double. It all depends on ambient temp, I would assume that Belize would be quite warm so it would mix quickly. My mixer is just a tank that holds 20,000 litres with a big recirculation pump, basically just pump in the water, put in the solids and leave to agitate. The other way to do it is to buy concentrated UAN liquid which is about 50%N I think then water it down but I think you can only buy that by the boatload! |

USA&Belize | Thanks for the info so far keep it coming :) Col please email me the recipes and mixing info If you can would love to here from you.
Tim thanks for the info you gave on the phone this will be really helpful. Brion

Flandreau, SD | how much would you want? |

south alabama | Col,
I am using 500 gallon tank with a recirculating pump to mix Urea and AN . I need a recipe for a starter mix and also need a recipe to use for side dressing. I do not want the mix too strong and burn my corn. Have you been mixing by weight or volume ? Have you added minor elements to your nitrogen mix ? |
