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 8 benchmarks together — the OptimalRange form drives the primary score, while 7 guard(s) constrain the result.
Evidence & Context
The optimal range for soil penetration resistance is defined as < 1500 kPa.
Range of soil penetration resistance values measured by cone penetrometer at field capacity indicating minimal or no limitation to ecosystem function.
This benchmark defines the optimal range of soil penetration resistance where soil compaction does not limit root growth or ecosystem function in temperate grassy woodlands and plains under livestock grazing.
This range encompasses the 'Not Compacted' and 'Mild' classes, representing a continuum of very good to acceptable soil physical condition for healthy temperate grazing systems.
