What is Triazone Fertilizer?

Triazone is widely recognized in the fertilizer industry for its unique chemical structure, known officially as 5-N-methyl-urea-1,3,5-triazin-2-one or 5-methyleneureido-2-oxohexahydro-s-triazine. This water-soluble compound delivers a minimum of 40% total nitrogen, making it a valuable source for sustained nitrogen release in both agronomic and specialty crop applications.

The Science Behind Slow-Release Nitrogen

Unlike quickly available nutrient fertilizers like ammonium nitrate or urea, triazone belongs to the category of slow- or controlled-release fertilizers. According to the official AAPFCO definitions, this means triazone releases its nitrogen over a much longer period, thereby delaying the nutrient’s availability for plant uptake after application. The result is extended nutrition, reducing risks of leaching and volatilization compared to rapid-release options.

Practical Benefits for Growers and Landscapers

For agricultural professionals, turf managers, and home gardeners, the controlled release nature of triazone fertilizers like Substain-N® translates to several real-world benefits:

More consistent plant growth due to steady nitrogen supply
Reduced need for frequent reapplication, saving time and labor
Environmental advantages including minimized runoff and greater sustainability

These factors contribute to healthier crops, greener turf, and enhanced yields, especially in regions prone to heavy rainfall or sandy soils where rapid-release fertilizers may wash away before plants can absorb them.[1]

Why Choose Triazone?

Products labeled as “Triazone” or “Substain-N®” have gone through official recognition and definition according to regulatory agencies like AAPFCO, so users can be confident they are getting a performance-tested ingredient. With a strong track record dating back to its official status in 1989, triazone is a trusted tool for those seeking long-lasting, effective nitrogen delivery.
