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™ Plus AV supports improved nitrogen efficiency, crop performance, and long-term soil productivity. Key benefits include:
- Extended Nitrogen Availability: Dual-action protection keeps nitrogen in plant-available forms longer by reducing both surface volatilization and subsurface losses.
- Improved Yield Opportunity: Maintains nutrient availability during critical growth stages, supporting stronger crop performance and more consistent yield outcomes.
- Flexible Application: Compatible with UAN, granular urea, and manure programs, making it easy to integrate into existing fertility plans across crops, soil types, and application methods.
- Supports Responsible Nutrient Stewardship: Helps reduce nitrogen loss to air and water, supporting sustainability goals and alignment with 4R Nutrient Stewardship.
- Part of a Complete System: Designed to complement Sylvite’s foliar nutrition, bio stimulants, and seed-applied technologies to support balanced, efficient crop nutrition.
SylLock™ Plus AV combines proven active ingredients and flexible compatibility to deliver reliable nitrogen protection across a wide range of programs.
- Dual-Mode Stabilization: Protects nitrogen through both urease and nitrification inhibition, reducing volatilization, leaching, and denitrification.
- Urease Inhibition Technology: Helps slow the conversion of urea to ammonia gas following application, especially valuable for surface-applied or minimally incorporated nitrogen.
- Nitrification Inhibition: Delays the microbial conversion of ammonium to nitrate, helping retain nitrogen in less mobile forms and extending plant availability.
- Broad Compatibility: Formulated for use with liquid and granular urea, UAN, and manure-based nutrient programs.
- Season-Long Protection: Supports nitrogen retention throughout key crop growth stages, helping align nutrient availability with plant demand.
- Operational Flexibility: Suitable for pre-plant, at-plant, sidedress, and topdress applications.

Frequently Asked Questions
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 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.
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.
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.
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.
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.
