While we continue to recommend the use of both UAN 28% & 32%, due to the nature of today’s changing market in fertilizers, we are unable to quote you a competitive price for the time being unless you are in MN, WI, & parts of IL & IA.

UAN 28% / UAN 32%

Online Quote Request Form for UAN 28% / UAN 32%UAN 28% and 32% are both formulations of the same thing, urea-ammonium nitrate, with a 28% nitrogen on one and a 32 % nitrogen on the other. The reason they have both forms is that 32% is how it's produced as a full concentrate and it's used more in southern climates. Then as it gets more in northern climates, especially if it's going to face a winter season, then they dilute it with water because the freezing point is less for the 28%. So the 32% more easily freezes and then it may drop off and salt up.

28% is a very good nitrogen and a pretty clean nitrogen, something we recommend because it's basically a nitrogen that's coming out of the air. It's a better source of nitrogen than anhydrous ammonia which is very hard on soil structure, it's very hard on all sorts of biology. But the 28% is a very good nitrogen. It's very important for corn production and we normally would always mix in 5-10 lbs of sugar when we're using that because you want to add in soluble carbons to slow-release the 28%.

One very nice formula that really goes good to make the nitrogen soil release is if you're using 10 gals. of 28% or 32%, you would add in your 5-10 lbs of dissolved sugar, then you could add in 1-2 gals of Thiosol and 1-2 gals. of ammonium sulfate and you could probably throw in a quart or two of liquid humates (RL37). That has all the components of an amino acid--nitrogen, carbon, hydrogen, oxygen, calcium, sulfates--and it really works good to hold the nitrogen throughout the season that way instead of losing it so quickly.

28% (or 32%) by itself is going to fairly quickly be lost to the atmosphere or leeched, so the nitrogen doesn't stay around so long. But when you put in the sugars and add some of the other components it will stay around much better and work for the plant.

Ammonium sulfate is a good product to use as a broadcast in conjunction with 28% or 32%. About 200 lbs of ammonium sulfate is pretty good and then take the rest of the nitrogen needs using 28% or 32%.

We can offer this in brokerage in approximately 4,000 gallon semi loads. It's available basically in bulk, we don't have much opportunity to sell it in totes at this point. But it is available for those who need larger quantities. Pricing varies frequently, so you have to request a quote. It is a good product and a pretty clean product for commercial fertilizers.

This would not be approved for organics, of course, because it's a commercial nitrogen.

    Earlier is Better!

    When it comes to getting your fertilizers for the Fall or Spring season, earlier is certainly better. For those of you interested in Florida soft rock phosphate, you probably are aware of the huge backlog and delays we had due to the bad weather down in Florida earlier this year.

    Well, the good news is that right now you can get bulk granular soft rock from Florida with no delays! It is ready and waiting for you! We can’t guarantee it will be that way for much longer as the Fall season is upon us and things tend to get busier. If you are thinking of making an order, earlier is better!
