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 2 benchmarks together — the OptimalRange form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context
A conservative, inferred benchmark for loams and clays under high-health regenerative management would logically fall in the upper end of, and likely exceed, the range observed for sands, plausibly in the order of 1500 – 3000 mg/kg.
Inferred total soil nitrogen benchmark range for loam and clay soils under best-practice regenerative agricultural management.
This benchmark represents an inferred range of total soil nitrogen in loam and clay soils under regenerative agricultural management, indicating higher nitrogen storage capacity and functional potential.
Inferred from functional data and biogeochemical principles due to lack of direct field measurements.
