Evidence & Context

Therefore, the optimal range for a high-health, resilient cropping system in Australia's Temperate Grassy Woodlands and Plains is 0.05 – 0.20 dS/m (EC₁:₅).

Metric Definition:

Soil Electrical Conductivity (EC) measured as EC₁:₅, indicating the concentration of dissolved ions in soil water.

Benchmark Definition:

This benchmark defines the optimal functional range of soil electrical conductivity that balances nutrient availability and salinity risk for resilient cropping systems in the Temperate Grassy Woodlands & Plains biome.

Justification:

Synthesized from lower and upper critical thresholds and ecological resilience goals.
