Soil Structure & Compaction
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
The optimal range for a high-health, regeneratively managed Vertosol in this biome is proposed to be < 1500 kPa. A soil in this state presents minimal mechanical impedance to root growth, water infiltration, and gas exchange. This value is designated as the Reference Value for the best available condition.
Soil penetration resistance measured as mechanical impedance to root growth and water infiltration in the root zone (0-30 cm) at or near field capacity.
The benchmark defines the optimal soil penetration resistance for soil structure and compaction in regeneratively grazed arid inland floodplains.
Derived from a synthesis of scientific principles and data from analogous systems, reflecting a state of minimal mechanical impedance and high ecosystem function.
