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 5 benchmarks together — the OptimalRange form drives the primary score, while 4 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
A persistent elevation of total soil nitrogen significantly above the 450 mg/kg benchmark is considered detrimental.
Upper detrimental threshold of total soil nitrogen concentration in the top 30 cm of soil.
Threshold above which total soil nitrogen causes negative ecosystem impacts in arid forest soils.
Defined by the onset of systemic degradation including invasive species promotion, nutrient imbalances, leaching, and soil acidification.
