Protecting Your UAN Investment With CENTURO Nitrogen Stabilizer

With unpredictable spring weather, protecting your nitrogen investment is critical to your overall yield potential. Environmental factors such as soil moisture, temperature, pH and compaction can all play a role in nitrogen loss.

Managing your soil pH, timing your UAN application for optimum soil conditions and using a nitrification inhibitor are all good management practices that can minimize nitrogen loss. And now, due to the researchers and developers at Koch Agronomic Services, you can protect your UAN three times longer than without an inhibitor. 1

Introducing CENTURO™ Nitrogen Stabilizer 

As the first nitrification inhibitor for anhydrous ammonia and UAN to be registered by the EPA in more than 40 years, CENTURO arms you with a proven tool to defend your fertilizer investment against denitrification and leaching. 

What Makes CENTURO Unique?

Developed over the course of nine years, CENTURO and its patented active ingredient, Pronitridine, deliver proven efficacy plus storage and handling benefits for operational efficiencies.

Nitrification occurs when applied nitrogen is converted from ammonium to nitrate. In the nitrate form your investment is susceptible to leaching and denitrification losses. As a nitrification inhibitor, CENTURO slows the conversion of ammonium to nitrate and can hold the nitrogen in the ammonium form three times longer than without an inhibitor.¹

Put simply, CENTURO extends your window of protection against the impact of environmental factors like temperature and moisture on the rate of nitrification. As shown in the model below, in spring applications, 100 percent of nitrogen applied without an inhibitor can be nitrified in two weeks at 75 degrees Fahrenheit. With CENTURO, less than 40 percent of the applied nitrogen would be nitrified.

CENTURO Performance and Protection of Nitrogen

When it comes to operational efficiencies, CENTURO has you covered there, too. This true liquid solution will allow you to say goodbye to cumbersome storage and transportation difficulties. CENTURO can easily pump directly into UAN without the need for recirculation. CENTURO is applied at 1.5 - 2.5 gallons per ton of UAN and is tank-mix compatible with many crop protection chemicals.2

Another major difference between CENTURO and other stabilizers is that CENTURO is 100 percent noncorrosive to UAN and anhydrous ammonia equipment — meaning you get the UAN protection you want without the potential damage to your equipment. 

From its in-field advantages to its unequaled flexibility, CENTURO delivers next-generation nitrogen protection in an easy-to-handle, effective nitrification inhibitor solution. To learn more about CENTURO, download the tech sheet or contact your KAS sales rep or visit your local retailer.

Nitrogen is one of the most critical nutrients for a corn crop and plays a large role in plant growth, development and yield potential. Depending on several environmental factors, nitrogen can be lost to from the rooting zone of the crop which can lead to a nitrogen deficiency.

The hard fact is that there are things on your operation that are out of your control. Spring rains and soil temperature both adversely impact your crop’s overall yield potential. But another fact is just as powerful – research has proven that the technology built into nitrification inhibitors can protect your UAN investment and your overall profitability.
