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 4 benchmarks together — the OptimalRange form drives the primary score, while 3 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
A steady-state infiltration rate below 5 mm/hr for Alpine Humus Soils under agricultural use would indicate significant degradation and impaired hydrological function.
Steady-state soil water infiltration rate, the rate at which water infiltrates soil after initial wetting, measured in mm/hr.
Lower critical threshold for steady-state soil water infiltration rate indicating significant soil degradation in Alpine and Subalpine Complex agricultural soils.
Indicates significant soil degradation (compaction, poor structure), increased runoff/erosion risk. Well below expected capacity of healthy Alpine Humus Soils and significantly lower than ARR Group C/D soils.
