Max In. Max Out.

Nitrogen is at risk from the moment it’s applied: Up to 30% of nitrogen loss happens above ground, and up to 70% can be lost below ground. Our nitrogen stabilizers deliver unrivaled technology to help you protect any nitrogen source, helping you get the max from your nitrogen when and where it counts.

New PinnitMax™ nitrogen stabilizer helps ensure above-ground nitrogen gets to the root zone. N-Serve® and Instinct® nitrogen stabilizers with Optinyte™ technology are proven to keep it there. Together, they work to maximize your nitrogen all season long — so you can get the max yield potential at harvest.

Any source of nitrogen is susceptible to loss through volatilization, leaching and denitrification. PinnitMax™ nitrogen stabilizer works above ground to reduce volatilization of urea and UAN. N-Serve® and Instinct® nitrogen stabilizers work below ground to help prevent leaching and denitrification for any fertilizer type.

N-Serve works with anhydrous ammonia, while Instinct maximizes nitrogen when used with UAN, urea and liquid manure.


Anhydrous ammonia (NH3)
Add N-Serve to BOTH spring and fall anhydrous ammonia to get the maximum benefit. Nitrogen protected with N-Serve can withstand early season moisture events by keeping nitrogen in the ideal ammonium form longer, so it can help maximize your yield potential.
UAN (28% or 32%)
Start with PinnitMax to help prevent volatilization above ground for up to 14 days, so your nitrogen can get to the root zone. Keep it there with Instinct, preventing spring rainfall from driving nitrogen lower into soil profiles and out of the reach of corn roots. Both are easily mixed with UAN fertilizer solutions to protect spring-applied nitrogen applications. Get the max from your UAN applications to get the max yield potential at harvest.
More Midwest farmers are adopting urea as their nitrogen source for spring, fall and sidedress applications. Use PinnitMax for above-ground protection to help prevent volatilization in the air and ensure valuable nitrogen gets to the root zone. Instinct also allows for easy impregnation onto urea applications for below-ground protection. No matter when you apply urea, make sure it’s protected so your crops receive the maximum nitrogen when they need it most.
Instinct can be easily mixed into the pit prior to liquid manure applications in spring or fall. University of Minnesota research shows Instinct® nitrogen stabilizer applied with fall swine manure provided 10- to 12-bushel-per-acre yield increase and reduced grain moisture by approximately 1.3 percentage points at harvest.1

N-Serve® and Instinct® nitrogen stabilizers are accepted for registration by the U.S. Environmental Protection Agency (EPA) and recognized for their proven benefits.
