The agricultural management of water repellent ( non-wetting) sands is difficult, and production from them is mostly low. However, there are ways to make them more productive.
Furrow sowing and the incorporation of dispersive clay are two likely methods to make these soils easier to manage, more productive and more profitable than they are now.
This article discusses several aspects of our research on water repellent sands. In addition, some of the costs and benefits of alternative management strategies are outlined.
