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 6 benchmarks together — the OptimalRange form drives the primary score, while 5 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
The lower critical threshold represents the point at which a soil's infiltration rate is so low that it fails to perform its essential hydrological functions, leading to a cascade of degradation processes.
Soil water infiltration rate below which hydrological dysfunction occurs.
Critical infiltration rate below which hydrological dysfunction occurs in temperate semi-arid shrublands and open woodlands under production forestry.
This threshold is based on soil structural assessment guides that classify infiltration rates of 0-10 mm/hr as indicative of very poor soil structure.
