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) in topsoil (0-30 cm) representing soil moisture content.
This benchmark represents the soil moisture content in the top 0-30 cm of soil in temperate grassy woodlands and plains under production forestry, where moisture levels between 20% and 25% volumetric water content support core ecological functions and ecosystem productivity.
The value is based on a lower critical threshold of <10% Volumetric Water Content (VWC) for productivity, identified in a temperate grassy woodland, and the global average plant water stress threshold of 19% VWC. A "best-on-offer" system should maintain a buffer above these stress points.
