NitroShield®
Reducing ammonia emissions by 70%+NitroShield is a urease inhibitor. NitroShield reduces ammonia emissions by 70%+ meeting industry guidance and helping farmers grow more efficiently and sustainably.
- Urease inhibitor
- Reduces ammonia emissions
- Improves nitrogen use efficiency
- Improves yield
- Improves protein levels
What is NitroShield and how does it work?
NitroShield is OMEX’s innovative urease inhibitor to reduce ammonia emissions and farm more sustainably. Defra has announced new rules on ammonia mitigation for urea fertilisers which include UAN liquid fertilisers, such as Nitroflo.
Including NitroShield in liquid nitrogen fertiliser applications will help farmers meet legislation whilst improving efficiency, and ensure they’re using the most effective application rates. NitroShield has undergone 3 years of rigorous testing to establish the most efficient and effective form of urease inhibitor available to farmers. NitroShield is an EU approved inhibitor.

70% reduction in emissions
The NitroShield urease inhibitor has repeatedly demonstrated over 70% reductions in ammonia emissions from urea containing fertilisers.
Improves NUE
With less ammonia lost to the atmosphere, and contained within the soil, the nitrogen applied alongside the NitroShield urease inhibitor is better utilised by the crop.
Meets Industry Guidance
NitroShield meets the government target of reducing ammonia emissions by 70%, helping farmers grow more sustainably.
Defra has announced rules on ammonia mitigation for urea fertilisers which includes UAN liquid fertilisers, such as Nitroflo. Farmers must inhibit their urea containing fertiliser application, excluding foliar applied urea, from 31st March each year. Further information can be found on the government website, here.
How farmers can reduce emissions from Urea containing fertilisers.- Defra are looking to reduce ammonia emissions by 70%, choose an inhibitor such as NitroShield that has been trialled to meet these standards. Take a look at our demonstrations below.
- Plan your fertiliser application wisely, you can use DIDIN if you chose to apply your full dose of liquid nitrogen fertiliser before 31st march, to prevent nitrate leaching and to improve NUE.
- Use the correct application rate. NitroShield can be used at a reduced or a full application rate to suit the farms requirements and to ensure you’re applying the optimum rate, improving nutrient use efficiency.
How NitroShield works to reduce ammonia emissions
NitroShield is a urease inhibitor that works by blocking the urease enzyme from hydrolysing urea which causes ammonia losses, helping farmers to reduce emissions and farm more sustainably. NitroShield has been specifically developed, and rigorously tested, to meet government guidelines on reducing ammonia emissions from 2024, in line with the Red Tractor Farm Assurance Standard.
Throughout the trials process the OMEX R&D team has worked to establish the most efficient rate farmers should use, to make sure they’re fully utilising their inputs and nothing is going to waste.
Research and Development of NitroShield
NitroShield has undergone years of rigorous testing. During these trials we’ve not only looked at how effectively NitroShield reduces emissions, but what the most efficient rate to use is.
Alongside our field trials we’ve been continuously testing the product in the lab, capturing gas emissions which meet international standards with NitroShield consistently reducing ammonia losses by more than 70%. We’ve also seen small yield increases when using the OMEX inhibitor, alongside NIAB trials showing a 0.3 t/ha increase in yield.

This trial demonstrated how effectively emissions were reduced when using NitroShield compared to a competitor product. The axis on the left represents ammonia emissions in ppm.
This trial demonstrated the improvement in yield when using the NitroShield urease inhibitor alongside the application of UAN liquid fertiliser, demonstrating an improvement in nitrogen use efficiency (NUE).
Farmer Benefits of using NitroShield
Grain yield in wheat trials from 30N + NitroShield v. 30N alone:
- 2016, NIABTAG Morley, UK +400 kg/ha
- 2017, NIABTAG Morley, UK +300 kg/ha
- Mean of trials in UK, CZ, PL +330 kg/ha
- 10 trials in France 2014-15 +0.2% Protein
Higher grain yield and protein = improved Nitrogen Use Efficiency
-
Utilising NitroShield, at the correct timings, helps farmers reduce ammonia emissions of the liquid fertiliser they apply by 70%+.
-
NitroShield is supplied separately from your liquid fertiliser. This is to improve on-farm efficiency and ensure inputs are only ever utilised when needed. NitroShield is mixed with the liquid fertiliser before application.
-
NitroShield urease inhibitor improved NUE (nitrogen use efficiency) by keeping the fertiliser crop available for longer, without leaching into the atmosphere as emissions.
