Evidence & Context

An infiltration rate of less than 10 mm/h is identified as the lower critical threshold for cropping systems in this biome.

Metric Definition:

Soil water infiltration rate below which soil function is critically impaired.

Benchmark Definition:

This benchmark defines the lower critical threshold for soil water infiltration rate below which soil degradation is severe in cropping systems of the Arid Inland Floodplains biome.

Justification:

Based on multiple sources including FAO guidelines and Australian soil health assessment tools indicating rates below 10 mm/h signify severe degradation.
