Soil Organic Carbon (SOC)

AUS-TCF-AGR-SOC General Low confidence

Benchmark Value

1.14 %
Direction: Higher is desirable ↑
Form: Point

Scoring Curve

Scoring curve unavailable

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

Benchmarks from agricultural districts in South Australia indicate mean SOC concentrations of 1.14% for pasture in the Western Eyre Peninsula.

Metric Definition:

Mean SOC concentration in agricultural pasture land within the biome.

Benchmark Definition:

This benchmark represents the mean soil organic carbon concentration in pasture agricultural land within the Temperate Coastal Forests & Woodlands biome, reflecting managed pasture conditions.

Justification:

Mean SOC values from agricultural districts provide a reference for managed land.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. This value reflects SOC levels in pasture land, which are slightly lower than undisturbed soils but typical for managed pastures. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
