Today, we have CENTURO, which has been scientifically proven to reduce nitrogen loss and optimize nutrient-use efficiency,” said Justin Hoppas, executive vice president of Koch. “Farmers throughout the Corn Belt are facing growing economic and environmental pressures, and we understand fertilizer additives must perform and pay off. CENTURO is now available as one more tool in a grower’s toolbox to increase agricultural efficiencies and optimize their crop nutrition investments.”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. In fact, in the first two years of an ongoing study conducted at Iowa State University, CENTURO reduced nitrate leaching by an average of 44% in fall-applied anhydrous ammonia and an average of 23% in spring-applied anhydrous ammonia compared to untreated anhydrous ammonia.“With so much focus on nitrate in our rivers and streams, calls for farmers to curb nitrogen loss are increasing,” said Jean Payne, president of the Illinois Fertilizer & Chemical Association. “Farmers are aware of this challenge and are voluntarily seeking products that can reduce the potential for leaching of nitrates into nearby waterways. Through our research in Illinois, we can confidently tell our farmers that when you use a registered nitrification inhibitor like CENTURO, your nitrogen is in the soil longer so more can be absorbed by the plant.”CENTURO holds 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.CENTURO also helps growers significantly improve nitrogen use efficiency (NUE) to increase crop output. Across a two-year study in Nebraska, Illinois and Missouri, CENTURO increased the NUE of anhydrous by up to 25%.
