Additional Metric Notes

Rationale

  • This metric is frequently used, scalable, and linked to nitrogen (N) and phosphorus (P) concentrations in receiving water bodies. Reporting total N and P as part of the calculations is important to prevent changes in efficiency from masking increases in overall inputs.
  • Nutrient Use Efficiency (NUE) and Phosphorus Use Efficiency (PUE) can be used to indicate nutrient loss at the edge of the field or nutrient surplus (1 – NUE or PUE). Note that N and P fertilizers are included in the SBTN High Impact Commodity List (HICL).

Additional/complementary metrics

  • Application rate & removal rate
