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 18 benchmarks together — the OptimalRange form drives the primary score, while 17 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 (SWIR) representing the intrinsic capacity of soil to transmit water through the profile once initially wetted.
A steady-state soil water infiltration rate below 5 mm/hr indicates significant impairment of soil hydrological function in agricultural Alpine Humus 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.
