Soil Nitrogen
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 3 benchmarks together — the OptimalRange form drives the primary score, while 2 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
Total N concentrations greater than 2000 mg/kg in these floodplain soils would be highly anomalous and likely reflect nutrient concentration rather than a healthy, functioning system.
Upper detrimental threshold of Total Soil Nitrogen concentration indicating ecological imbalance and risk of weed invasion.
This benchmark defines the upper limit of Total Soil Nitrogen concentration in floodplain soils, above which ecological imbalance and increased risk of invasive species occur.
Inferred from ecological context indicating values above this level may favor invasive nitrophilic weeds and represent degraded states.
