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 10 benchmarks together — the OptimalRange form drives the primary score, while 9 guard(s) constrain the result.
Evidence & Context
The optimal range for sustainable productivity and ecological health is estimated to be 1000-2500 mg/kg for sandy soils and 1700-3400 mg/kg for clay/loam soils.
Optimal functional range of Total Soil Nitrogen for sustainable productivity and ecological health.
Optimal range for Total Soil Nitrogen supporting robust production and minimizing environmental risk.
Range based on SOC thresholds and nitrogen supply suitable for different soil textures.
