Water Nitrate
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.
Evidence & Context
The derived benchmark is <0.050 mg/L N
Water nitrate concentration (represented as oxidised nitrogen NOx, the sum of nitrate-N and nitrite-N)
A realistic and defensible target for a high-health, sustainable grazing system within a working landscape, based on QLD Gov WQOs.
Selected as a derived proxy based on the Queensland Government's Water Quality Objective (WQO) for oxidised nitrogen in 'Developed fresh water' within the Johnstone River Basin due to a lack of direct, published field measurements from verifiably 'best-practice' or 'regenerative' grazing sites.
