Water Nitrate

AUS-TSR-AGR-WNI General Moderate confidence

Benchmark Value

0.005 mg/L
Direction: Lower is desirable ↓
Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

The recommended reference value for water nitrate is 0.005 mg/L as Nitrate-Nitrogen (NO3 N).

Metric Definition:

Water nitrate concentration in runoff from best-practice agricultural systems in Australia's Tropical and Subtropical Rainforests biome.

Benchmark Definition:

This benchmark represents the reference concentration of water nitrate in agricultural runoff that reflects the highest achievable environmental health state in Tropical & Subtropical Rainforests under agricultural crop production.

Justification:

This value is derived from the median Dissolved Inorganic Nitrogen (DIN) concentration reported for the minimally disturbed Daintree Basin, serving as a real-world proxy for a high-health system.

Notes

No lower critical threshold exists. The natural baseline of ~0.005 mg/L is the ideal state. The optimal range starts at this baseline upwards with no ecological benefit to higher concentrations and increasing ecological risk. Lower concentrations indicate better ecosystem health and on-farm nutrient use efficiency. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
