ANVOL® nitrogen stabilizer from Koch Agronomic Services (Koch), featuring the patented active ingredient — Duromide — delivers the longest-lasting urease inhibitor protection over a wider range of soil environments. Utilizing Duromide, ANVOL protects your nitrogen investment against ammonia volatilization while also reducing overall labor demands.
Driven by Duromide technology, ANVOL protects your nitrogen investment by inhibiting urease, preventing ammonia volatilization and preserving nitrogen for crop uptake. It also offers a high active ingredient concentration, enabling a low application rate for more efficient coating operations.
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 features a patented active ingredient – Duromide – designed to extend the protection of nitrogen above ground.
ANVOL provides improved performance across a range of soil conditions with varying pH levels for protection growers can count on.
ANVOL features a high active ingredient concentration that enables a low application rate.
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.
A Virginia Tech corn study conducted in 2016, when averaged across all nitrogen rates, showed urea treated with ANVOL increased yield by 11 bu/acre compared to urea treated with AGROTAIN®, and 66 bu/acre when compared to untreated urea.
In a 2019 Michigan study, UAN treated with ANVOL yielded 27 bu/acre more than untreated UAN.
Bars with different letters are significantly different at p<0.10 Yield based on N-rate of 180 lbs N/ac.

With ANVOL, growers benefit from a rapid inhibition response (kick-start effect of NBPT) and extended protection as a result of active ingredient Duromide. ANVOL increases the window of inhibition by up to 27% compared to NBPT alone.3
