Soil Organic Carbon (SOC)
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 13 benchmarks together — the OptimalRange form drives the primary score, while 12 guard(s) constrain the result.
Evidence & Context
An inferred optimal range for healthy, resilient floodplain grazing soils is 1.5% to 4.0% SOC.
Optimal range of Soil Organic Carbon (SOC) for healthy and resilient floodplain grazing soils
This benchmark defines the optimal range of Soil Organic Carbon that supports a healthy, resilient, and productive grazing system in floodplain soils of this biome.
This range signifies a system that is functioning well, is resilient to climatic stress, and is well above a state of degradation.
