How does Nitro-Guard Urea work?

Nitro-Guard is granular urea that has been treated with a urease inhibitor called Limus®. This unique product works by temporarily blocking the urease enzymes from converting urea into ammonia until the urea has been sufficiently washed into the ground and gives it time to move into the soil, buffering the pH spike and minimising losses.  Developed by BASF, Limus® is the most modern chemistry formulation in protected urea.  It is a unique combination of NBPT and NPPT and is 40% more efficient than competitor products containing NBPT alone. Due to its chemistry, Limus® is a more broad spectrum product which enables it to bind to a wider variety of urease enzymes in the soil.

What are the benefits?

Nitrogen is essential for grass & crop growth, protected urea products containing registered urease inhibitors including NBPT and NPPT have been identified by Teagasc as the No.1 technology to reduce ammonia and nitrous oxide losses in the atmosphere and can also help improve water quality.

Teagasc Trials have found that protected urea consistently gives the same yield as CAN.

ADAS Trials have found a 5% (0.5t/ha) increase in cereal yield with Limus®.

Teagasc analysis has shown that protected urea represents good value as it is less costly per unit of N than CAN and it can be spread throughout the growing season.

Nitro-Guard User Guidelines

  •  While Nitro-Guard can be applied throughout the season, it is recommended to avoid application during periods of drought or snow or when ground is waterlogged.
  •  Don’t forget to calibrate and correctly set your spreader as urea has a different bulk density than CAN.
  • Follow safe fertiliser handling guidelines and as with any chemical it is advisable to wear gloves and protective clothing when handling fertiliser.
