Soil Organic Carbon (SOC)
Benchmark Value
Scoring Curve
The scoring engine could not generate a curve for this benchmark context. The primary form is Point, 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 benchmark of 1.6% for finer-textured soils (e.g., Sodosols) is based on initial SOC levels at the MASTER experiment site, reflecting the higher carbon storage potential of clay soils.
Soil Organic Carbon (SOC) content in the 0-10 cm soil layer for finer-textured soils under best-practice agricultural cropping systems.
SOC benchmark representing the best available condition for finer-textured soils in the biome.
Reflects the scientifically sound principle that soils with higher clay content can maintain higher SOC levels, based on initial SOC at the MASTER trial site.
