Soil Water Infiltration Rate
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 7 benchmarks together — the OptimalRange form drives the primary score, while 6 guard(s) constrain the result.

Evidence & Context
A Lower Critical Threshold is established at ²64 5 mm/hr. Rates below this level are indicative of severe soil structural degradation, such as compaction or sodicity, which compromises long-term productivity and ecosystem health by increasing runoff and erosion risk.
Lower Critical Threshold for Soil Water Infiltration Rate indicating severe soil structural degradation.
The infiltration rate below which soil structural degradation is severe and ecosystem health is compromised.
Based on field data indicating that infiltration rates ²64 5 mm/hr correspond to severe degradation such as compaction and sodicity.
