Uncovering the dirt on soil and water
With water conservation such an important issue, it’s surprising that less than one in four commercial irrigators in Australia actually measure the amount of water in their soil. In this vodcast, Dr Richard Stirzaker from CSIRO Land and Water demonstrates how soil holds water much like a sponge, each day allowing plants to extract some of this water via their roots and transpire it through their leaves. Dr Stirzaker also explains that accurate irrigation is simply replacing the water thats been lost, a task achievable by monitoring soil water with one of the many commercial products available, such as the CSIRO FullStop wetting front detector. www.csiro.au www.fullstop.com.au
