Soil Nitrogen
Benchmark Value
Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is Point, 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.
Evidence & Context
The full report provides benchmarks for other soil textures (e.g., Sandy Loam: 1400 mg/kg; Clay Loam: 2200 mg/kg).
Total soil nitrogen (TN) concentration in topsoil (0-30 cm) layer.
Total soil nitrogen concentration in the 0-30 cm topsoil layer for Sandy Loam soils in the Australian Arid Mountain Ranges & Uplands biome under agricultural crop production.
Derived from the 90th percentile of modelled TN values from the CSIRO SLGA dataset as a proxy for best available condition due to lack of direct field data.
