Abstract
Despite salinization is one of the most widespread soil degradation processes and affects between 1 and 3 million hectares in the European Union, the measurement of exchangeable cations concentration of soil generates some problems related to the intensity and duration of these laboratory tests for determination. In these context it is desirable to determine relationships between certain models of soil salinity indices. One of these indicators is soil Exchangeable Sodium Percentage (ESP), which is determined using laborious and time consuming laboratory tests. Therefore it may be more appropriate and economical to develop a relationship which uses a more simple soil salinity indicator. Therefore, the main objective of this study is to propose a pattern ESP-SAR for salinized soils from investigated perimeter of Osoi-Moreni, Iaşi County, Romania. The research required the use of pairs of samples, which were collected and processed as the indicated above, to compare ESP values measured by laboratory tests with data from the application of the linear regression equation SAR-ESP. The Bland-Altman method (Bland and Altman, 1999) was used to compare the results from laboratory tests with the results of SAR-ESP model. Statistical analyzes were performed using Microsoft Excel (version 2010).
