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 13 benchmarks together — the OptimalRange form drives the primary score, while 12 guard(s) constrain the result.
Evidence & Context
Values significantly above the optimal range (e.g., >2000 mg/kg) may indicate nutrient concentration and imbalance (high N:P ratio), increasing the risk of weed invasion and representing a degraded state rather than high health.
Upper detrimental threshold of Total Soil Nitrogen concentration indicating ecological imbalance and risk of degradation.
This benchmark represents the upper detrimental threshold of soil nitrogen concentration above which ecological imbalance and degradation risk increase in arid inland floodplains and ephemeral river systems under livestock grazing and pasture.
Inferred from ecological context of high N:P ratio favoring invasive nitrophilic weeds and nutrient concentration in patches.
