Abstract

In this article, we reviewed properties of reclaimed tidal soil and fate of nitrogen in its soil. The results were summarized as followings. Most of the soil derived from the fluvio-marine deposit were silly textured soils. The EC of the Saemanguem soil were ranged from 14.7 to 33.9 dS $m^{-1}$, pH was 7.7. The organic matter content was low with 1.5 g $kg^{-1}$. The cation exchange capacity was 7.2 cmol $kg^{-1}$ and exchangeable sodium percent was high with range 45.1 % to 56.2%. High sodium concentration caused poor drainage. The salinity significantly affects efficiency of N fertilizer in reclaimed tidal soil.
