Stabilized Turf Nitrogen (STN)
When untreated urea is surface applied, up to 40% of its nitrogen can be lost through volatilization. Protect your investment and achieve consistent results using Award Turf Fertilizer treated with STN. STN is a specially designed urease inhibitor that defends against volatilization by inhibiting the naturally occurring urease enzyme. With more nitrogen available in the soil, and not the atmosphere, your turf is ultimately greener and healthier.
Recognized by the Association of American Plant Food Control Officials (AAPFCO) as a stabilized nitrogen, you are ensured that Award Turf Fertilizer products with STN will obtain optimum results and has the efficacy data that meets state compliance requirements.
