Soil Structure & Compaction

AUS-TSR-LVG-SSC General Moderate confidence

Benchmark Value

No specific value — see range
Range: 1000 to 2000 kPa
Optimal Range: 1000 to 2000
Direction: Lower is desirable ↓
Form: OptimalRange

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

A penetration resistance of 1000–2000 kPa represents a limiting or marginal condition where root growth begins to be restricted.

Metric Definition:

Soil penetration resistance (PR) in kPa indicating mechanical impedance to root growth.

Benchmark Definition:

This benchmark defines the marginal soil penetration resistance range where root growth starts to be restricted, indicating a transition from healthy to stressed pasture soil conditions.

Justification:

Indicated by multiple sources as a transition zone from healthy to stressed soil conditions.
