Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

The benchmark for Sand soil texture is Field Capacity (FC) at 8 - 12% volumetric %.

Metric Definition:

Volumetric water content of soil at Field Capacity (FC), the maximum amount of water available to plants after drainage.

Benchmark Definition:

Field Capacity (FC) is the volumetric water content of soil after saturation and drainage, representing the optimal water available to plants in Tropical & Subtropical Maritime Islands under Livestock Grazing & Pasture.

Justification:

This benchmark is derived synthetically due to a lack of direct field measurements for the specified context. The reference value, representing high ecological health, is set at Field Capacity (FC), the optimal state for plant water availability.

Notes

Lower Critical Threshold: 5.5 %. No upper detrimental threshold — higher values are always better up to natural saturation. The functional range includes critical thresholds for ecosystem health and productivity.
