Soil Organic Carbon (SOC)
Benchmark Value
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.

Evidence & Context
A Lower Critical Threshold is identified at <1.0% SOC, below which critical ecosystem functions are compromised.
Lower critical threshold of Soil Organic Carbon (SOC) concentration in the 0–10 cm soil layer below which ecosystem functions degrade
This benchmark defines the minimum Soil Organic Carbon concentration below which soil functions are impaired and degradation risk increases in the Australian semi-arid biome under livestock grazing.
Based on broad surveys of Australian agricultural soils indicating SOC below 1.0% is indicative of degradation.
