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
An optimal functional range is estimated to be 900-1400 mg/kg, reflecting values observed across arid to semi-arid high-condition floodplain sites.
Optimal functional range of Total Soil Nitrogen concentration supporting healthy ecosystem function.
This benchmark defines the optimal range of soil nitrogen concentration that supports healthy ecosystem function in arid inland floodplains and ephemeral river systems under livestock grazing and pasture.
Based on values from high-condition arid and semi-arid sites and higher rainfall semi-arid floodplains.
