Soil Organic Carbon (SOC)

AUS-TDG-LVG-SOC General Moderate confidence

Benchmark Value

1 %
Direction: Higher is desirable ↑
Form: MinimumOnly

Scoring Curve

Scoring curve unavailable

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

An SOC level of <1.0% in the 0-10cm layer is proposed as a lower critical threshold for Temperate Dry Woodlands & Native Grasslands under livestock grazing.

Metric Definition:

Lower critical threshold of Soil Organic Carbon (SOC) concentration in the 0-10 cm soil layer below which essential soil functions are significantly impaired in Australian Temperate Dry Woodlands & Native Grasslands under livestock grazing.

Benchmark Definition:

This benchmark defines the critical lower threshold of Soil Organic Carbon below which soil function and ecosystem health are severely impaired in temperate dry woodlands and native grasslands under livestock grazing.

Justification:

Based on evidence from degraded landscapes showing severe impairment of soil functions and ecosystem health below this SOC level.

  • Region Australia
  • Biome Temperate Dry Woodlands & Native Grasslands
  • Land Use Livestock Grazing & Pasture
  • Assessment Not Stated
  • Evidence Type DegradationThreshold

Lifecycle

  • Status Active
  • Version 1
  • Effective From 3 Jun 2026

Notes

SOC concentrations below 1.0% indicate severe degradation and loss of essential ecological functions in the target biome. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
