Benchmark Value
Scoring Curve
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
While a precise numerical value is difficult to ascertain from available literature, it is clear that levels significantly above the natural benchmark (e.g., >2000–2500 mg/kg) would indicate a dysfunctional system at high risk of these negative consequences.
Upper detrimental threshold for Total Soil Nitrogen above which ecosystem function is impaired
This benchmark defines the upper detrimental threshold of total soil nitrogen in the topsoil above which ecosystem function is impaired in temperate semi-arid shrublands and open woodlands under production forestry.
Levels significantly above the natural benchmark (e.g., >2000–2500 mg/kg) indicate a dysfunctional system at high risk of negative ecological consequences.
