This study was carried out to investigate the properties of soil and water under Double-cropping SSH followed by whole crop barley (SSFWB) or by Hairy vetch (SSFHV) in paddy land. A field study was conducted at Baeksan-myeon, Kimje, Jeonbuk province in Korea on clay loam soil for 3 years. All plots were arranged in completely randomized design with three replicates. The pH and the contents of T-N and organic matter (OM) in soil samples collected at the end of the experiment were remarkably higher t㏊n those at the beginning of the experiment in both SSFWB and SSFHV treatment (P＜0.05). The contents of an exchangeable cations at the end of the experiment were remarkably higher t㏊n those at the beginning of the experiment in both SSFWB and SSFHV (P＜0.05). And then, the concentration of NO₃-N, NH₃-N and PO₄-P in discharge and leaching water were not influenced by the cropping system
