Nitrous Oxide Reductions Protocol

Fertoz is now helping producers accumulate carbon credits through the NERP protocol, which has been approved and registered through CSA in May, 2022.

Application of nitrogen from synthetic and organic fertilizer, biological fixation, manure fertilizer and crop residues is an important part of agricultural production. Nitrogen in the soil is subject to emission as N2O either from nitrification/denitrification pathways in the soil, losses through leaching of nitrate, and/or volatilization and redeposition of ammonia gas. Management practices which synchronize the availability of nitrogen with the requirements of the crop, minimize the emissions of N2O per unit of crop mass. This can include tillage practices and or the use of organic, sustainable and or slow-release N fertilizers.

Implement farm management practices that increase nitrogen use efficiency (NUE) using the 4R strategy.

NERP minimizes these N2O emission pathways by managing on-farm applied nitrogen sources through the implementation of the best management practices described by the 4R Plan. This 4R Plan is a risk-based approach, informed by over 40 years of peer-reviewed research on the effect specific management practices have on the biological processes that lead to nitrogen losses in North American cropping systems. The 4R Plan is designed to address the risk of nitrogen losses by promoting comprehensive nitrogen management across the 4Rs:

  • Right Source - Slow / controlled release fertilizers or inhibitors
  • Right Rate - Using annual soil testing and recommendations developed within the 4R Plan
  • Right Time - Apply in spring, split application, or once soil has cooled to 10°C
  • Right Placement - typically banded/ injected

The greater the NUE increase, the more offsets that are generated. Furthermore, NERP can be combined with other programs such as no-till to increase the amount of carbon offsets generated.

Implementing a 4R management strategy can help:

  • Optimization of the crop response per unit of added nitrogen; and,
  • Minimization of the risk for nitrate-N to accumulate or persist in the soil where it is potentially denitrified and/or emitted directly or indirectly as N2O or lost from the system through leaching and runoff.

Let Fertoz be your carbon specialist. We provide agronomic services, sustainable crop solutions, carbon credit advisory and trading. Our carbon programs can be stacked to maximize returns on your farms’ carbon offset initiatives. We currently offer NERP and Conservation Cropping (No-Till) programs, but are working to provide a host of other carbon programs in the near future including cover cropping, canola strategies, methane reductions in cattle, and sustainable fertilizer programs.
