Calculating Readily Available Water at the Macalister Irrigation Farm

A soil pit was recently dug at the Macalister Demonstration Farm (MDF) to better understand the Readily Available Water (RAW) content of the farm. RAW is the approximate amount of water measured in millimetres, held in the soil that is easily available to plants.
This water can be used by plants …
