Soil pH
Benchmark Value
Scoring Curve
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
"The soil was not pretreated to remove carbonates because the average soil pH at the site was 5.3 (n = 480)."
Average bulk soil pH across a large grid sampling effort in the topsoil horizon.
Reference-condition baseline soil pH for intact conservation reserves in box-gum grassy woodland clay-loam soils.
Sourced from a major ecological experiment in highly intact conservation reserves, summarizing a large-scale (n = 480) sampling effort representing reference woodland soils.
