Soil Moisture
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
Numerically, for a representative loam soil with a PWP of ~10-15% VWC and an FC of ~25-35% VWC, the optimal range for topsoil moisture during active growing seasons would likely be from approximately 18% VWC to ~35% VWC.
Optimal soil moisture range supporting high ecological function and sustainable grazing.
The optimal soil moisture range supports vigorous native perennial growth, active soil biological processes, and sustainable grazing in temperate dry woodlands and native grasslands under livestock grazing.
This range is derived from typical PWP and FC values for loam soils and reflects functional soil moisture during active growing seasons.
