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 in cropping systems.

Benchmark Definition:

This benchmark defines the lower critical threshold for soil water infiltration rate indicating severe degradation in cropping systems within the biome.

Justification:

This threshold synthesizes multiple sources including FAO guidelines and Australian soil health assessment tools indicating rates below 10 mm/h signify severe degradation and ecological dysfunction.

  • Land Use Agricultural Crop Production
  • Assessment Pristine Reference
  • Evidence Type DegradationThreshold

Lifecycle

  • Status Active

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. Rates below this level indicate severe runoff and erosion risk, poor water capture, and compromised productivity.
