Soil pH

Benchmark Value

5.17 pH

Direction: Higher is desirable ↑

Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

"pH | 4.16 | 6.38 | 5.17 | 0.53"

Metric Definition:

Topsoil (0–10 cm) pH measured via a 5g field soil to 25 ml DI water extract (Method 4A1).

Benchmark Definition:

Reference-condition baseline soil pH for sub-humid temperate woodland.

Justification:

Represents a high-integrity, predator-proof conservation reserve (Mulligan's Flat-Goorooyarroo) containing critically endangered grassy eucalypt woodland remnants.
