nitrogen in soil


  • Nitrogen Stabilizer

N-Serve slows the conversion of ammonium to nitrates, reducing leaching and denitrification. They maximize yield potential by ensuring more of your applied nitrogen stays in the root zone in a stable, useable form until your canola, corn and wheat crops need it.


There are many benefits to protecting your anhydrous ammonia with N-Serve:

Protect your nitrogen investment

eNtrench NXTGEN icon soil retention

Healthy crops start with healthy soil. N-Serve works below the soil’s surface to help retain 28% more nitrogen in the soil longer so it’s available when crops need it for maximum growth.

Optimize yield and profit potential

eNtrench NXTGEN icon more weeks

Corteva Agriscience research trials demonstrate an average yield increase of 8% in canola, 7% in corn and 6% in wheat. By extending nitrogen availability in the soil for up to eight weeks, N-Serve keeps nitrogen available and ready when your crop needs it most: during critical growth stages.

Reduce environmental impacts

eNtrench NXTGEN icon greenhouse gas

The exclusive Optinyte™ technology found in N-Serve decreases denitrification, reducing greenhouse gas emissions by 51%. N-Serve also reduces the leaching of nitrates into groundwater by 16%.

Expand your application options and save time

With N-Serve, apply your anhydrous ammonia up to two weeks earlier than you would typically apply in the fall. Take advantage of reduced cost of fertilizer in the fall and save time for seeding operations in the spring.
