In an effort to improve the active-ingredient technology in urea and UAN nitrogen stabilizer products, Koch Agronomic Services (KAS) developed Duromide. Designed as a more stable molecule, Duromide boosts efficacy and extends the protection from ammonia volatilization already provided by NBPT. The benefits of Duromide can only be found in ANVOL® nitrogen stabilizer — learn more about the longest-lasting protection from ammonia volatilization below.
For years the standard in nitrogen stabilization has been the active ingredient NBPT — the same active found in the leading urease inhibitor AGROTAIN®. Duromide is a molecule developed to work in tandem with NBPT to deliver protection from ammonia volatilization that starts quickly and lasts longer than NBPT alone.
NBPT is an effective, fast-acting molecule that set the bar for nitrogen stabilization nearly 25 years ago. But as time passes, elements like temperature and soil pH will degrade NBPT.
Duromide is a robust molecule that is resistant to degradation triggers, allowing it to extend your window of above-ground nitrogen protection.
“And doing a lot of research in this area, I thought to myself, ‘we’ll probably never see a urease inhibitor that works better than NBPT’, and after seeing Duromide, I think I’m going to have to change my thoughts on that.”
— Dustin Harrell, agronomy project leader at Louisiana State University AgCenter’s rice research station
When Duromide is paired with NBPT — as found in ANVOL nitrogen stabilizer — you get benefits that go beyond the added stability in the field. Benefits like a high active ingredient concentration, consistent performance and more efficient coating operations.
The patented design of Duromide allows it to stand up in various environments and fertilizer blends. It is designed to extend the protection of nitrogen, allowing fertilizer more time to be incorporated into the soil.
Duromide combined with NBPT delivers an optimal range of above-ground nitrogen protection from ammonia volatilization. In a 2016 LSU rice trial, ANVOL with Duromide reduced cumulative ammonia loss to 12 percent, compared to losses of more than 30 percent with untreated urea.
ANVOL offers a high active ingredient concentration, allowing for a low application rate. Duromide technology contributes to more efficient coating operations across a wide variety of impregnation methods and reduced fertilizer buildup on equipment with its drier urea fertilizer blend.
