In this study, leaching experiments were carried out by both continuous and alternate ponding methods
in the south of Khouzestan province. In equal applied water leaching, alternate ponding leaching
model had a better performance than continuous ponding method in desalinization and dealkalization.
In term of alternate method,there was not ayn difference between 5 and 8 day periods in one-meter
depth. Even thought the trends of desalinization and dealkalization showed a slight difference,
particularly in early stayes, the figure of two alternative methods were the same, finally. Obtained
results were compared with the results of other researchers experiential models. Comparison of
desalinization field experiment results and models result’s showed that Dieleman model a relationship
based on experimental and theoretical opinion had a better performance than the other experiential
models. The performance of this model in alternate ponding method was better than continuous
ponding method. More ever, based of soil analysis results, due to enough amount of calcium in soil
after leaching, there did no need reclamation materials.
