Changes in Soil Salinity and Alkalinity During Two Years of Irrigation with Saline Groundwater in the Semihumid Carpathian Basin

The effects of irrigation over a two-year period with shallow groundwater were evaluated for two typical areas of the Great Hungarian Plain. The site at Kunmadaras has light-textured soil, and the site at Karcag has heavy-textured soil. No adverse effects of irrigation with groundwater were evident at the Kunmadaras site with light-textured soil. An increase in subsoil alkalinity but not soil salinity was found at the Karcag site with heavy-textured soil.
