Soil Moisture

AUS-AKW-CON-SMO General Moderate confidence

Benchmark Value

No specific value — see range
Range: 4 to 6 % VWC
Optimal Range: 4 to 6
Direction: Higher is desirable ↑
Form: OptimalRange

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

the reference value is established as 4-6% volumetric soil moisture.

Metric Definition:

volumetric soil moisture

Benchmark Definition:

The critical minimum soil moisture required to sustain the community through prolonged inter-pulse drought periods.

Justification:

This value is derived by linking the ecophysiological water stress limit of keystone chenopod shrubs (survival at soil water potentials down to approximately -8.0 MPa) with the water retention properties of representative arid Calcarosol soils.
