Evidence & Context

Soil Water Infiltration Rate 50 - 70 mm/hr represents the average infiltration rate for well-structured soils under best-practice pasture management in the temperate grazing lands of Central West NSW.

Metric Definition:

Soil Water Infiltration Rate (SWIR) is the rate at which water enters the soil, reflecting the soil's capacity to absorb rainfall and support ecosystem functions.

Benchmark Definition:

This benchmark defines the optimal soil water infiltration rate range for well-structured soils under best-practice pasture management in temperate grazing lands, indicating healthy soil function and water absorption.

Justification:

This benchmark is based on quantitative data from NSW Local Land Services and supported by multiple credible sources linking high infiltration rates to best-practice grazing management and soil health.

Notes

No upper detrimental threshold exists; higher infiltration rates are consistently beneficial. The optimal range corresponds to systems with >70% groundcover, minimizing erosion and runoff. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
