Here are some tips to keep in mind when storing anhydrous ammonia/N-Serve® nitrogen stabilizer:

  • Ensure all facilities, equipment and installations meet with federal, state and local codes and regulations. 
  • Use stainless steel totes, avoiding moisture. 
  • N-Serve® nitrogen stabilizer must be stored in a closed handling system to prevent spillage to items that may not be compatible. 
  • A storage temperature of 18 degrees Fahrenheit or higher must be maintained to avoid crystallization. 
  • Pumping units must be flushed with kerosene at the end of the season 
  • Always follow specifications for tanks and trailers. 
  • Inspect tanks and trailers, looking for dents, thinning, corrosion, paint issues, placard issues, loose anchor bolts, etc. 
  • Change relief valves within five years of the date of manufacture. 
  • Fully empty everything and drop the pressure to zero when making repairs. 


Here are some tips to remember when transporting anhydrous/N-Serve:

  • Follow state-specific regulations, which you can find at your local department of agriculture. 
  • Travel at or below 25 miles per hour. 
  • Add a slow-moving vehicle (SMV) emblem to the towing assembly to alert other drivers. 
  • Check state regulations regarding the number and status (full or empty) of tanks you can pull. 
  • Always use a hitch pin with a safety keeper/retainer clip and two independent safety chains when towing. 
  • N-Serve tanks with a capacity of 120 gallons or more require placards.
