Evidence & Context

a derived reference value for an Alpine Humus Loam could be targeted at approximately 35-40% VWC.

Metric Definition:

Soil moisture, quantified as volumetric water content (VWC)

Benchmark Definition:

This benchmark represents the optimal volumetric water content range (35-40%) for Alpine Humus Loam soils in the Australian Alpine and Subalpine Complex under agricultural crop production, indicating conditions that support healthy plant growth and soil biological activity.

Justification:

This range signifies conditions where water is readily available, supporting vigorous plant growth and active soil biological processes, which are hallmarks of a healthy agroecosystem.
