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
An optimal range for soil penetrometer resistance in this context would be one that supports healthy, extensive root systems for native plant species, facilitates optimal water infiltration and soil aeration, and fosters a thriving soil biodiversity, all within the framework of sustainable livestock grazing.
Range of soil penetrometer resistance values conducive to healthy root systems and soil function under sustainable grazing.
This benchmark defines the optimal range of soil penetration resistance that supports healthy root systems, water infiltration, and soil biodiversity under sustainable livestock grazing in temperate dry woodlands and native grasslands.
Based on agronomic thresholds and ecological considerations, the optimal range is likely <1500 kPa, ideally <500 kPa, to avoid root restriction and promote good soil physical condition.
