CENTURO nitrogen stabilizer is a new nitrification inhibitor from Koch Agronomic Services, Wichita, Kansas, for anhydrous ammonia and urea ammonium nitrate. The product recently received EPA registration under the Federal Insecticide, Fungicide and Rodenticide Act, or FIFRA, and is now available for order in the United States.
The approval of CENTURO marks the first time in more than 40 years that a nitrification inhibitor for anhydrous ammonia has received FIFRA registration.
“CENTURO is now available as another option, a proven option to help growers minimize nitrogen loss and maximize their nutrient-use efficiency and yield potential,” said Greg Schwab, director of agronomy with Koch.
CENTURO works to protect applied nitrogen and keep the valuable nutrient available in the root zone in its ammonium form where it’s less susceptible to loss through denitrification and leaching. By keeping nitrogen in a stable form for a longer period of time, more of the nitrogen is available to be absorbed by the plant, and there is less potential loss to the environment.
By slowing the conversion of ammonium to nitrate, CENTURO can hold the nitrogen in the ammonium form three times longer than without an inhibitor. With fall-applied anhydrous ammonia, more ammonium will be held in the soil throughout the spring, maximizing availability for crop uptake. And with spring-applied anhydrous ammonia, CENTURO helps minimize potential losses to leaching and denitrification from spring rains prior to crop establishment.
In keeping more nitrogen available for plant uptake, research has shown CENTURO can improve yields as well. Across a two-year study in Nebraska, Illinois and Missouri, when compared to untreated fall-applied and spring-applied ammonia, respectively, CENTURO-treated ammonia increased corn yield by an average of 8 bushels per acre in fall applications, and by an average of 7 bushels per acre in spring applications.
