Abstract :This study was carried out under field conditions in Konya-Karatay District Erler Village\\\'s soils to determine the leaching water requirement and sulfur levels for reclamation of salinc-sodic soils of Konya plain. The study was planned randomize plots trial design as three replications. In study, powder sulfur as 80% purity was used for reclamation. Total 210 cm leaching water was applied with a 30 cm increment. According to the results, to leach the 59% of the total soluble salt, equal to 1 time of leached soil depth; for 72%, 2 times and for 80%, 3 times water should be applied. In addition, leaching equation and figure are presented for leaching water in order to leach the salts in 1 m soil depth. In study, sulfur with on increment doses resulted in more improvement; having applied 210 cm leaching water for application of 0,5 t/da sulfur, exchangeable sodium percentage (DSY) reduced below the 15% in total 1 m soil profile while in application of 1 t/da sulfur, DSY reached to the this ratio after application of 180 cm leaching water.
