%X Selenium contents were determined in the A horizon of the Salsodisols (Solonchaks and Solonetz)placed along the C lm  ui and Buz u Valleys. The total selenium content oscillated between 480 and 1140 g¡¤kg-1, with an average value of 800  g¡¤kg-1. This value is 2.1 times higher than the selenium total content inthe upper horizon of the World¡¯s non-halomorphic soils. It is also higher than the selenium total content in the upper horizon of the soils from Dobrogea and the South-Eastern Romanian Plain, 5.6 respectively 3.4 times. The mobile selenium content, soluble in the EDTA-CH3COONH4 solution at pH = 7, ranged in the 13-25  g¡¤kg-1 interval, with an average value of 18  g¡¤kg-1, 4 times higher than the mobile selenium contents of the Dobrogea soils upper horizon and 1.2 times higher than the ones in the South-Eastern part of the Romanian Plain. Between the selenium total contents and some Salsodisols physical and chemical properties proportionality relations were established, statistically ensured. Most of these soils¡¯ selenium content is to be found as calcium, sodium, or magnesium (secondary) selenates. The presence of the same cations¡¯ selenites is not excluded.
