While fall is a great time for nitrogen applications, it comes with varied weather conditions and the risk of nitrogen loss, making it beneficial to use a nitrification inhibitor such as CENTURO™ nitrogen stabilizer.

CENTURO is a nitrification inhibitor that growers can now use with anhydrous ammonia to help protect against nitrogen loss from leaching or denitrification. Nitrification inhibitors are an important tool for protecting applied nitrogen and keeping the valuable nutrient available in the root zone in the ammonium form where it’s less susceptible to loss.

By slowing the conversion of ammonium to nitrate, CENTURO, as shown in the graph below, can hold nitrogen in the ammonium state three times longer than untreated ammonia¹. With fall-applied anhydrous, more ammonium will be held in the soil through the spring, maximizing availability for crop uptake.

By keeping more nitrogen available for plant uptake, research has shown CENTURO can improve nutrient-use efficiency and yields. Using CENTURO also follows the recommendation of the 4R Nutrient Stewardship Initiative, by keeping nutrients available when crops need them, and where the crops can use them. When it comes to protecting fall-applied nitrogen, don’t leave it to chance – protect your investment with CENTURO.
