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
Based on this principle, a reference value of 20% - 25% VWC is proposed for topsoil (0-30 cm) in the loamy to clay-loam soils typical of this biome.
Volumetric Water Content (VWC) of topsoil (0-30 cm)
This benchmark represents the optimal volumetric water content range in topsoil for loamy to clay-loam soils in temperate grassy woodlands under production forestry, indicating a moisture state that supports core ecological functions without limitation.
This reference value is a derived synthesis representing a resilient state for loamy to clay-loam soils, set comfortably above documented stress thresholds including a lower critical threshold of <10% VWC for productivity and a global average plant water stress threshold of 19% VWC.
