Evidence & Context

Table 1 presents these derived benchmarks, translating the concept of Field Capacity into specific volumetric percentages for different soil types, thereby directly addressing the user query.

Metric Definition:

Volumetric water content at Field Capacity (FC), the point at which soil holds the maximum amount of water available to plants after drainage.

Benchmark Definition:

This benchmark represents the optimal volumetric soil moisture range at Field Capacity for Clay Loam soil texture under livestock grazing in tropical maritime islands.

Justification:

Derived from Rab et al. (2014) data on Australian dryland cropping soils, representing the maximum plant-available water.
