Soil Water Infiltration Rate

AUS-TSW-FOR-SWI General Moderate confidence

Benchmark Value

110 mm/hr
Direction: Higher is desirable ↑
Form: MaximumOnly

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

Rates > 110 increase the risk of nutrient leaching, though less severely than in pure sands.

Metric Definition:

Upper infiltration rate threshold beyond which nutrient leaching risk increases in loamy sand soils.

Benchmark Definition:

Upper infiltration rate threshold for nutrient leaching risk in loamy sand soils in temperate semi-arid shrublands and open woodlands under production forestry.

Justification:

Loamy sand soils have a moderate risk of nutrient leaching at infiltration rates above 110 mm/hr.

Notes

The benchmark values represent a healthy balance of infiltration and retention. Exceeding this threshold increases nutrient leaching risk.
