Incorporating Wetting and Non-wetting Sands


These photos came from a farm we visited who had delved his non wetting sand, aiming to incorporate the wetting sand beneath. The results are visually obvious. It is important to consider the pros and cons of delving, as it may take away the ability to water harvest using the non wetting sand in the inter-row as a funnel to channel the water into the root zone. In this instance, delving may have been the right option, however it is very expensive per hectare, and the longevity of the benefits are yet to be seen.
