SylLock™ is Sylvite’s line of nitrogen stabilizers, designed to reduce nitrogen loss from volatilization, leaching, and denitrification. By keeping more nitrogen in the soil, it ensures better nutrient availability for crops, improving efficiency and yield potential.
SylLock™ – Crop Nitrogen Management System
Product Details
Advanced Nitrogen Stabilization for Maximum Efficiency – SylLock™ is Sylvite’s premium line of nitrogen stabilizers, designed to protect your fertilizer investment by reducing nitrogen loss through volatilization, leaching, and denitrification. By keeping nitrogen in the soil longer, SylLock™ products ensure greater nutrient availability for plants, improved efficiency, and higher yield potential, all while supporting environmental stewardship.
With multiple formulations tailored to different application methods, SylLock™ offers cost-effective, easy-to-use solutions to maximize nitrogen retention and optimize plant uptake, ensuring your fertilizer dollars go further.
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™ and how does it work?
Which SylLock™ product is right for my farm?
SylLock™ comes in three formulations, each targeting a specific type of nitrogen loss. SylLockUp™ inhibits volatilization, keeping nitrogen from escaping into the air. SylLockDown™ prevents leaching and denitrification, helping nitrogen stay in the root zone for longer. SylLockPlus™ combines both technologies for dual-action protection, offering the most comprehensive solution. A Sylvite representative can help determine which option best fits your needs.
How does SylLock™ improve fertilizer efficiency?
By keeping nitrogen in the root zone for longer, SylLock™ ensures plants absorb more of the applied fertilizer, reducing nutrient waste and input costs while supporting higher yields.
Is SylLock™ environmentally friendly?
Yes! SylLock™ supports sustainable farming by reducing ammonia emissions and nitrogen runoff, aligning with 4R Nutrient Stewardship principles to protect soil health and water quality.
