Evidence & Context

The benchmark range of 145×206 mm/h represents the pinnacle of this optimal state≤the "best-on-offer" condition achievable through sustained, best-practice management.

Metric Definition:

Optimal functional range of soil water infiltration rate balancing water capture and nutrient leaching risk.

Benchmark Definition:

This benchmark indicates the optimal functional range of soil water infiltration rate reflecting good to excellent soil health and water capture with nutrient management considerations in the biome.

Justification:

Rates above 70 mm/h indicate good to very good soil structure and function; the upper range reflects best-practice management but requires nutrient management to mitigate leaching risk.
