Protecting nitrogen today requires more than just slowing one loss pathway. NLock Advanced combines the power of NBPT and DMPP — two industry-proven technologies — to create a dual-action nitrogen stabilizer that protects against both ammonia volatilization and nitrate leaching and denitrification. By using NLock Advanced, you stabilize nitrogen both above ground and below ground — ensuring more of the fertilizer you apply reaches your crops when they need it most, optimizing your fertility investment.
How NLock Advanced Works
NLock Advanced is not a single chemical — it’s a strategic combination of two precision tools: NBPT (Inhibits the urease enzyme, Reduces ammonia volatilization from urea and UAN fertilizers, Protects nitrogen on the soil surface after application) and DMPP (Inhibits nitrifying bacteria (Nitrosomonas), Slows the conversion of ammonium to nitrate, Reduces nitrate leaching and denitrification risks below ground). Together, they form a powerful, synergistic protection system — maintaining nitrogen in plant-available forms longer than either technology alone, enhancing your nitrogen fertility.
Why Dual Protection Matters
Traditional single-mode stabilizers (NBPT only) protect against surface loss but do little once nitrogen moves into the soil. Traditional nitrification inhibitors (DMPP only) protect soil nitrogen but don’t prevent early surface volatilization losses. By combining both, NLock Advanced: Reduces early surface nitrogen loss (ammonia volatilization), Reduces later-stage soil nitrogen loss (leaching and denitrification), Improves nitrogen use efficiency (NUE), Supports stronger early growth and sustained yield development, Enhances return on fertilizer investment — especially under unpredictable weather conditions.
Key Features and Benefits
Dual action protection: surface and subsurface nitrogen stabilization, Prolonged nitrogen availability during critical growth stages, Reduced greenhouse gas emissions (ammonia and nitrous oxide), Supports better stand establishment, stronger biomass, and grain fill, Field-proven to increase crop nitrogen recovery and yield potential.
Active Ingredient
NBPT: 18% or 30% depending on formulation. DMPP: 15%.
Application Guidelines
Target Fertilizers: Urea, UAN. Recommended Application: Applied as a liquid coating onto dry urea or injected into UAN solutions. Specific rates customized based on crop type, fertilizer blend, soil temperature, and moisture risks.
