Adding ANVOL stabilizer to your nitrogen strategy


It’s not just smart planning; it’s the right call


Every year, growers are confronted with a daunting challenge: How do you protect your nitrogen investment from ammonia volatilization while also implementing the tools and practices needed to boost yield potential?

Difficult though it may be, growers and agronomists are discovering that with the right combination of smart planning and the use of an effective nitrogen stabilizer, it’s possible to overcome such demanding circumstances. It’s a philosophy defined by one basic principle: Your nitrogen deserves more.

Give more. Get more.

Nitrogen stabilizers are proven to minimize nitrogen loss and increase nitrogen use efficiency. For many years, growers relied on AGROTAIN® nitrogen stabilizer from Koch Agronomic Services (Koch), along with its active ingredient NBPT, to assist with this critical process. Now, many of those same growers are turning to a next-generation product from Koch to give their nitrogen more protection and more flexibility.

ANVOL® — a next-generation urease inhibitor — is giving more operations the power to protect against volatilization while also allowing them to get more for their fertilizer dollar. Utilizing a stabilizer has become more than a best practice. It’s now an essential step for anyone needing to protect their nitrogen from many of the uncontrollable factors like soil quality and rain levels.

What makes ANVOL different from AGROTAIN?

The difference is Duromide — the Koch-patented active ingredient that works in tandem with NBPT. Whereas AGROTAIN features NBPT alone, ANVOL nitrogen stabilizer has taken protection to a whole new level by giving both growers and retailers a dual active-ingredient advantage. NBPT blocks the hydrolysis of urea as soon as it’s applied, while Duromide provides efficacy beyond the window of protection offered by NBPT alone — allowing fertilizer more time to incorporate in a wider range of soil environments.

A yield advantage you can’t ignore

A 2020 Nebraska study showed UAN treated with ANVOL resulted in higher corn yields compared to untreated UAN at all three nitrogen rates (60, 120 and 180 lbs N/ac).1


As more research becomes available, the power of ANVOL becomes increasingly evident. Applying a proven stabilizer prevents the loss of nitrogen to the environment by keeping it where it’s needed most, giving growers more potential to deliver higher yields.

Work smarter and save

Whenever your nitrogen is lost to ammonia volatilization, your return on investment decreases. But equally as troublesome to your bottom line as lost nitrogen is lost time.

With ANVOL, protecting nitrogen and increasing your efficiency go hand-in-hand. Dan Durst, Manager at Premier Cooperative in Mount Horeb, Wisconsin, explains it best. “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.”

By reducing nitrogen loss, you may also reduce the need for an additional nitrogen application. This can have a significantly positive impact on growers, as it’s another major timesaver. Because of the high active-ingredient concentration and low treatment rate of ANVOL, growers can decrease labor demand and save valuable time.

Make the call

While you can’t control everything, your smartest move is to focus on what you can control. Applying ANVOL stabilizer is the best way to minimize nitrogen loss and get more out of your fields. Make a plan to benefit from the dual active ingredients of ANVOL. Ask your local retailer about ANVOL or speak with a Koch sales representative to get started.
