In 2007, 144 million cubic meters of water was used in Switzerland to irrigate around 43,000 hectares on a regular basis and 12,000 hectares on an occasional basis, with the inner-alpine dry valley of the Valais accounting for more than half of the irrigated surface area [9]. The water used for this purpose is taken primarily from water courses, particularly during dry seasons or climate periods, and used directly without any interim storage.

In soils of arid climates, higher electrolyte concentrations favor Na and adsorption on exchange sites. Regardless of climate, periodic cycles of soil wetting and drying are likely to produce wide fluctuations in electrolyte concentrations, with the result that the cationic composition of the soil s exchange sites is not constant.
