SylLock™ Plus AV is a dual-action nitrogen stabilizer designed to protect applied nitrogen from loss. It combines urease and nitrification inhibition to reduce volatilization, leaching, and denitrification, helping keep nitrogen in plant-available forms longer so crops can use more of what you apply.
SylLock™ Plus AV – Crop Nitrogen Management System
Product Details
Dual-Action Nitrogen Protection for Maximum Crop Performance – Every pound of nitrogen you apply should contribute to crop performance, not disappear into the air or move beyond the root zone. SylLock™ Plus AV is designed to protect that investment by reducing loss pathways and extending nitrogen availability throughout the growing season.
Built for both granular and liquid urea, UAN, and manure-based programs, SylLock™ Plus AV delivers dual-mode stabilization. By defending against surface volatilization and slowing subsurface nitrogen conversion and movement, it helps ensure more applied nitrogen remains available when crops need it most.
The result is improved nutrient efficiency, stronger plant uptake, and more consistent performance across variable weather and soil conditions. Instead of reacting to nitrogen loss, SylLock™ Plus AV enables a proactive strategy that supports higher yields and better return on fertilizer investment. Powered by proven urease and nitrification inhibition technologies, it provides season-long protection you can rely on to help convert fertilizer dollars into measurable agronomic outcomes.
SylLock™ Down
Prevent Nitrogen Leaching & Improve Nutrient Retention – SylLockDown™ contains dicyandiamide (DCD), a highly effective nitrification inhibitor that slows the conversion of ammonium to nitrate, reducing nitrogen leaching and denitrification. This ensures nutrients remain available longer, allowing plants to absorb more nitrogen for stronger, healthier growth.

Frequently Asked Questions
What is SylLock™ Plus AV and how does it work?
What types of fertilizer programs is SylLock™ Plus AV compatible with?
SylLock™ Plus AV is designed for use with UAN, granular urea, and manure-based nitrogen programs. Its flexible formulation allows it to integrate easily into most existing fertility plans without major changes to equipment or application practices.
When should I apply SylLock™ Plus AV?
SylLock™ Plus AV can be used in pre-plant, at-plant, sidedress, or topdress applications. It is especially beneficial when nitrogen is applied ahead of peak crop demand or when conditions increase the risk of nitrogen loss, such as warm soils, high rainfall, or irrigation.
How does SylLock™ Plus AV improve yield potential?
By maintaining nitrogen availability during key growth stages, SylLock™ Plus AV helps support stronger plant development and consistent crop performance. Retaining more nitrogen in the root zone allows crops to access nutrients when they need them most, improving overall nutrient use efficiency.
Does SylLock™ Plus AV support sustainable farming practices?
Yes. By reducing nitrogen loss to the air and water, SylLock™ Plus AV supports responsible nutrient stewardship and aligns with 4R Nutrient Stewardship principles. This helps improve environmental outcomes while enhancing the efficiency of fertilizer inputs.
Can SylLock™ Plus AV be used as part of a broader nutrient management strategy?
Absolutely. SylLock™ Plus AV is most effective when integrated into a complete nutrient management system that considers timing, placement, and complementary technologies. When used alongside foliar nutrition, biostimulants, and seed-applied solutions, it helps support balanced crop nutrition and long-term soil productivity.
