Soil Organic Carbon (SOC)

AUS-TMS-AGR-SOC General Moderate confidence

Benchmark Value

No specific value — see range

Range: 1.8 to 3 %

Optimal Range: 1.8 to 3

Direction: Higher is desirable ↑

Form: OptimalRange

Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

Optimal SOC ranges, conducive to high productivity and ecosystem health, are suggested as 1.8% to 3.0% for fine-textured soils, 1.5% to 2.5% for medium-textured soils, and 1.2% to 2.0% for sandy soils.

Metric Definition:

Optimal SOC range (0-10cm)

Benchmark Definition:

This benchmark defines the optimal Soil Organic Carbon (SOC) range in the 0-10cm soil layer for fine-textured soils in tropical monsoonal savannas, supporting high productivity and ecosystem health.

Justification:

Range conducive to high productivity and ecosystem health.
