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
Extremely high rates, more typical of gravels/sands. Potential for excessive nutrient leaching or drought stress if WHC is low.
Steady-state soil water infiltration rate, the rate at which water infiltrates soil after initial wetting, measured in mm/hr.
Potential upper detrimental threshold for steady-state soil water infiltration rate indicating possible adverse effects in Alpine and Subalpine Complex agricultural soils.
Detriment is highly conditional and depends on soil texture, depth, nutrient management, and rainfall patterns.
