Just asked my supplier today. But the actual idea is to keep it the N where you need it. True, it could be washed away but if you're doing right by your soil, it will be held there. I think I would speak to someone not selling me something. Do you Have an agronomist who does your soil testing rec's? They're not typically in the business to make money. See what they rec'd for the best yield and for price.
King City, Mo. What about scratching the N in with the field cultivator? NC Iowa. Only choice? Buy your own applicator and start putting money in your pocket. Buy wholesale chems and ferts and do what's right when the time is right. And you will discover that you can raise more with a lot less.
It is more work. Is that the normal agrotain cost up north? That sounds super high. I'm not familiar with the new agrotain, just the original though. From what I gather anything beyond the original nbpt agrotain is snake oil. At those rates it would pay for your own equipment to donit yourself. We are spreading urea right now with nbpt on it as 7 day has very little rain in it but 10 day looks better.
Running about The stuff works for volatization that's a fact. As someone else said it doesn't do anything else so I say use it if your worried about volatization. NE Iowa. Not sure how much urea and how much UAN you are using. Agrotain on urea only protects the N from volatilizing gassing off if not incorporated. It doesn't help it stick around or protect in from leaching if you get heavy rains. If you apply Agrotain treated urea on top and it rains within 24 hours the Agrotain was a total waste of money.
Now if you apply Agrotain treated urea to moist ground and it stays warm and humid for a week but doesn't rain then it is saving you a lot of N. Now UAN is a slightly different animal. Half of the N is ammonium nitrate which is much more stable. Only half the N in UAN is from urea and subject to loss. One protects it from volatilizing just like regular Agrotain and the other slows down the conversion to nitrate which will protect the N from leaching from saturated soils.
Haven't bought any "Plus" in the last 7 or 8 years so not sure what it currently costs. I recommend treating or not treating depending on weather. How good are the rain chances after application? Some years I treat mine and some I don't but most times I go ahead and treat it as "insurance" in case the weather man is wrong. Glasgow, Ky. Significant factor in your decision is how many acres you are talking about. Assume you are using liquid N and hiring the spraying done.
AGROTAIN is the most proven urease inhibitor on the market—backed by more than 1, trials and over 20 years of real-world results on millions of acres worldwide. Research proves that even at lower temperatures, nitrogen loss is still a risk. Research shows that urea treated with AGROTAIN gives growers the same yield performance as ammonium nitrate fertilizer, but with fewer regulatory, transportation and storage issues. Studies conducted by land-grant universities across the Midwest show that AGROTAIN-treated urea outperformed other stabilizer products in both nitrogen protection from ammonia volatilization and yield results.
