Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is CompositeFramework, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.
Contributing Benchmarks
Evidence & Context
The derived benchmark for a high-health state is an estimated 1000 mg/kg of total nitrogen in the topsoil (0–30 cm).
Total Soil Nitrogen concentration in the topsoil (0–30 cm)
This benchmark represents the estimated total soil nitrogen concentration in the top 30 cm of soil that indicates a high-health state in production forestry within the Arid Inland Floodplains & Ephemeral River Systems biome in Australia.
This value is derived from mean total nitrogen values in topsoils (0–30 cm) of uncleared, mature native Eucalyptus and Acacia woodlands in semi-arid Queensland, which serve as the best available proxy for a high-health ecosystem state that sustainable forestry should maintain.
