Koch Agronomic Services Launches CENTURO A-PRO Nitrogen Stabilizer
Koch Agronomic Services (KAS) has announced the launch of CENTURO A-PRO nitrogen stabilizer, a higher concentrated formulation of its proven nitrification inhibitor, CENTURO, designed to provide a more flexible and easy-to-handle nitrogen protection solution for retailers and growers. CENTURO A-PRO recently received successful registration and approval from the Environmental Protection Agency (EPA).
Available for Fall 2026 applications, this next-generation nitrogen stabilizer builds on the same user-friendly profile of the original CENTURO, now with three times the patented active ingredient Pronitridine and a lower use rate for anhydrous ammonia and UAN applications. CENTURO A-PRO nitrogen stabilizer gives retailers and growers an effective tool to improve nitrogen availability by minimizing below-ground nitrogen loss from leaching and denitrification, supporting stronger crop performance, optimized yield potential and improved return on investment. It works by slowing the conversion of ammonium to nitrate, effectively keeping nitrogen in the root zone longer for better crop uptake.
“Retailer feedback played a key role in the development of CENTURO A-PRO,” said Kurt Gabrielson, vice president, research and development. “They asked for a lower use rate, and we built on the proven performance of CENTURO to deliver exactly that. CENTURO A-PRO maintains the trusted benefits of the original formulation while helping growers maximize the value of every nitrogen application. We’re excited for retailers and growers to begin using it this fall.”
Retailers and growers benefit from the superior ease of use both in the field and at the storage site. With its higher concentration, CENTURO A-PRO requires less product to be stored, freeing up on-site storage space and reducing the total volume handled for improved operational efficiency. Like the original CENTURO formulation, it features a low-odor, 100% noncorrosive formulation for the metals used in anhydrous and UAN equipment, helping reduce the risk of unplanned downtime to keep growers operating when it matters most. With a per-ton mixing rate, CENTURO A-PRO simplifies use in variable-rate fertilizer applications compared to stabilizers applied on a per-acre basis.
In independent trials across the United States, CENTURO A-PRO has demonstrated increased nitrogen use efficiency and yield potential in anhydrous ammonia and UAN applications. In anhydrous ammonia fertilizer applications, early trials in corn have shown an increase in yield of up to 18 bu/ac versus untreated anhydrous ammonia applications at a rate of 180 pounds of nitrogen per acre.
“CENTURO has delivered proven performance for growers for several years, and we are actively committed to delivering innovation that both boosts yield performance and operational efficiency,” said Gabrielson. “With the EPA approval of CENTURO A-PRO, we are moving the industry forward again with enhanced solutions that improve nitrogen availability by reducing loss to help ensure crops meet their full potential.”
