Centuro A-Pro is the answer

Meet
CENTURO™ A-PRO

You asked for a more concentrated formula, and we answered with CENTURO™ A-PRO nitrogen stabilizer. It is three times more concentrated than the original CENTURO formulation and boasts a lower application rate for anhydrous ammonia and UAN applications. Just like the original CENTURO formulation, it’s proven to perform when it matters most.

checkOptimize nitrogen use efficiency and yield

Higher Concentration, Lower Application Rate

With its improved operational efficiency, this formulation requires less product to be stored, maximizing on-site storage capacity and reducing the total volume that needs to be handled.

Optimized NUE & Yield

The improved formula with patented active ingredient Pronitridine, minimizes nitrogen loss from leaching and denitrification, optimizing nitrogen use efficiency and yield for improved ROI.

Easy to Handle & Store

The 100% noncorrosive formula is easy to use and gentle on your storage equipment.

Less product. Less hassle.

With the higher concentration of CENTURO A-PRO, you get the job done with a fraction of the storage space. Treat 500 tons of anhydrous ammonia with just one tote of CENTURO A-PRO compared to three totes of the original formulation. For 500 tons of UAN? Still just one tote, instead of five. That's fewer totes to move, less space to manage, and a whole lot more efficiency.
