Short summary
Soil quality depends on water availability for plants. Sandy soils with a poorly permeable layer (fragipan) are considered inept for agriculture. However they are cultivated in Namibia as they secure a minimum harvest during droughts. In order to understand the hydrological influence of fragipans in these soils, soil moisture content was measured. The results illustrate that the combination of sandy topsoil and shallow fragipan has beneficial effects on plant-available water during dry periods.
