Koch Agronomic Services expands its nitrogen stabilizer portfolio with Centuro A-Pro designed to stabilize anhydrous ammonia and UAN ensuring nitrogen stays in the ammonium form longer.
As Cody Hornaday, technical agronomist with Koch Agronomic Services, explains the development of Centuro A-Pro was rooted in customer feedback for a more concentrated formula that offers enhanced operational efficiency.
“Koch is big on customer voice,” he says. “We took feedback on Centuro, and basically concentrated the product down to a higher concentration of active ingredient. Therefore, we could then lower the use rate. We now have launched Centuro A-PRO.”
Representing approximately a 67% reduction in the volume of product handled, the lower use rate of Centuro A-Pro is 1.61 gallons per ton of anhydrous ammonia compared to 5 gallons per ton for the original Centuro formulation.
“It is a concentrated formulation of the original Centuro, we are maintaining the same amount of active ingredient per ton of nitrogen. Therefore we get a lower use rate, and we get much more efficiency by handling less volume,” he says. “You still get the same great nitrogen stabilization below ground against denitrification and leaching, but we handle a whole lot less product and get the same effect.”
For retailers, this means operational efficiency realized in less storage needed and improved inventory management due to the lower volume. And for farmers, this equates to faster turnaround times when filling tanks, allowing for more efficient application during tight application windows.
“It’s a win-win for retailers and growers alike,” Hornaday says.
KAS says early trials in corn have shown up to an 18 bu/ac increase versus untreated anhydrous ammonia applications at an application rate of 180 pounds of nitrogen per acre. The company plans to have its full product launch for the fall 2026 application season.
Strategic Fit in the Koch Portfolio
“Nitrogen stabilizers are a tool to ensure that a grower is using all of that nitrogen that they are applying,” Hornaday says. “We want to ensure that Mother Nature doesn’t take away any of that through volatilization or denitrification or leaching, because we know that it’s one of the most expensive inputs that a grower’s going to use for a corn crop.”
He continues, “We’re just looking at trying to be as efficient with the pounds that we’re putting on as we can. Losing any of the money that you put out on a crop that’s already at a tight margin is certainly not what anybody wants to do.”
Continued product development for nitrogen stabilizers underscores how the topic is important—and farmers seek to be efficient with the nitrogen they are buying and applying in any economic environment.
Here’s an outline of the KAS nitrogen stabilizer lineup:
Above-Ground Protection (Urease Inhibition):
- Agrotain: The NBPT based product that KAS says set an industry standard for stabilization for urea and UAN.
- Anvol: The current flagship product featuring the Duromide molecule, designed for a longer window of protection against volatilization.
Below-Ground Protection (Nitrification Inhibition):
- Centuro (Original): The established product for anhydrous ammonia and UAN stabilization.
- Centuro A-PRO: The high-efficiency evolution of the below-ground portfolio, specifically targeting growers and retailers who prioritize speed and reduced product handling.
