N-FIXX® DURO is a specialized fertilizer additive that reduces the loss of nitrogen that occurs when urea-based fertilizers are surface applied to crops. N-FIXX® DURO inhibits the activity of urease – an enzyme that converts urea nitrogen into the more volatile ammonia form. By reducing the formation of ammonia nitrogen, the loss of nitrogen from surface-applied fertilizer is minimized. N-FIXX® DURO is applicable for use with any nitrogen-consuming crop when used in conjunction with urea-based fertilizers.

N-Fixx Duro controls nitrogen loss through ammonia volatilization with trusted NBPT and new, patented duromide. With dual active ingredients enhanced with Flowtech® Formulation Technology, it strengthens nitrogen protection and improves fertilizer applications. Like NBPT, duromide is a urease inhibitor, but it breaks down at a slower rate. Combining these active ingredients makes N-Fixx Duro more resistant to soil degradation, which extends the window of nitrogen protection. N-Fixx Duro controls nitrogen loss and increases efficiency in diverse growing conditions. With Flowtech Formulation Technology, it provides application benefits with both urea and UAN.
