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
The derived benchmark for a high-health state on loamy soils is an SOC concentration of 1.0% to 1.2% in the top 0–10 cm.
Soil Organic Carbon (SOC) concentration in the 0–10 cm soil layer representing the best available condition for high ecological health in loamy soils within the biome.
SOC concentration representing the best available condition for high ecological health in loamy soils of the biome.
Derived by inference from a well-managed, low-intensity grazing system in a NSW semi-arid woodland, supported by studies linking higher SOC to high perennial plant cover, a key indicator of ecosystem health.
