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 2 benchmarks together — the OptimalRange form drives the primary score, while 1 guard(s) constrain the result.

Evidence & Context
A critical lower threshold below which ecosystem function is significantly impaired is estimated to be less than 1.0% SOC. Below this level, the fertile clay soils typical of the biome become highly vulnerable to degradation.
Critical lower threshold of Soil Organic Carbon (SOC) below which essential soil functions degrade.
This benchmark defines the critical minimum soil organic carbon level below which soil functions degrade and land degradation risk increases in the arid inland floodplains biome under grazing.
Inferred from general soil science principles and expert knowledge due to lack of specific biome data.
