Form: OptimalRange

Scoring Curve

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

Evidence & Context

For heavier-textured clay and clay loam soils, achievable best-practice benchmarks are lower, estimated to be in the range of 10 - 25 mm/hr.

Metric Definition:

Soil Water Infiltration Rate (SWIR) measured as the rate at which water enters the soil profile under field conditions.

Benchmark Definition:

This benchmark defines the optimal soil water infiltration rate range for heavier-textured clay and clay loam soils under regenerative management, reflecting improved soil structure within physical constraints.

Justification:

Synthesized from multiple data points reflecting achievable improvements over baseline infiltration rates for heavy soils.

Notes

This range reflects the physical constraints of heavier soils but indicates significant improvement through regenerative management. No upper detrimental threshold — higher values are always better up to natural saturation.
