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 19 benchmarks together — the OptimalRange form drives the primary score, while 18 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
Optimal Range: pH(CaCl₂) 5.5 to 6.5 This range represents the "sweet spot" for overall pasture ecosystem health.
Soil pH measured in calcium chloride solution (pH(CaCl₂)) representing the optimal range for pasture ecosystem health and productivity.
The optimal soil pH range for maximizing nutrient availability, minimizing toxicity, and supporting soil microbial and pasture health in the Tropical & Subtropical Maritime Islands biome.
Supported by multiple lines of evidence including nutrient availability, toxicity avoidance, and microbial activity optimization.
