Give it extended protection with ANVOL® nitrogen stabilizer.
Improve your nitrogen use efficiency with ANVOL and its dual active ingredients: Duromide and NBPT. By combining NBPT — the proven active ingredient in AGROTAIN® — with the patented active ingredient Duromide, you get the longest-lasting protection against ammonia volatilization over a wider range of soil conditions. That’s because Duromide was designed to extend the protection of nitrogen currently offered by NBPT alone.
With two active ingredients working in tandem, ANVOL gets to work faster and provides a longer duration of protection from nitrogen loss through volatilization. To top it all off, ANVOL is low odor and reduces total labor demands with more efficient handling and lower treatment rates.
Ammonia volatilization can have a serious impact on your yield results and reduce your return on investment. In research studies, ANVOL has been proven to defend against volatilization and boost yield results compared to untreated urea.
Urea treated with ANVOL consistently resulted in higher corn yields starting at 60 lbs N/acre.
Urea treated with ANVOL resulted in a 31 bu/acre average corn yield advantage over untreated urea.

Driven by Duromide technology, ANVOL extends the protection of your nitrogen investment so more of the applied nitrogen is available for crop uptake and less is lost to ammonia volatilization. ANVOL is also more efficient. With a high active-ingredient concentration you get lower treatment rates, a drier finished urea fertilizer blend, improved coating operations and less buildup on equipment.
The intelligent design of Duromide has proven to hold up in various environments. When compared to other urease inhibitor technologies, ANVOL is the clear winner with its ability to perform better in conditions that favor high volatilization.
ANVOL stabilizer features a patented active ingredient – Duromide – designed to extend the protection of nitrogen above ground.
ANVOL stabilizer provides improved performance across a range of soil conditions for protection growers can count on.
ANVOL helps reduce labor demands with lower treatment rates for more efficient coating and a drier finish that improves handling.
A lot of ANVOL benefits are the same as we had with AGROTAIN — but with dual active ingredients, the different mode of action helps out even more to minimize volatilization. Duromide really separates it from the generics and the knockoffs on the market. Using Koch-branded products has also always been a big plus — we know our rep from Koch and we know what we’re working with.

Before using ANVOL, one of the biggest challenges of using other stabilizers was the ammonia smell that it produced when you mixed it with urea and ammonium sulfate. And you know that smell. It was very hard to work around because it would take your breath away. My employees struggled with it. There was really nothing to combat that smell, other than some respirator training.

When you’re really challenged with time, the lower use rate with ANVOL allows us to move the product around faster and get it into our spreading equipment. In addition to that, we’re using less volume and less product going out on that urea. It dries faster and helps out with less handling.

In recent research, ANVOL demonstrated extended protection against nitrogen loss due to volatilization.
Urea treated with ANVOL provided a statistically significant wheat yield advantage of 3 bu/acre over untreated urea averaged across 40, 60, 80 and 100 lbs N/acre.
