Soil saIinization is a serious eco-pedological limiting factor, particularly for plants sensitive to even very low salt concentrations. In the Etosha National Park in northern Namibia eight soil types can be distinguished that show different levels of the electrical conductivity (EC5) and a typical vertical distribution of salts in the soil profile.
