To evaluate effect of flood and inundation of the Mekong River to land fertilization in Cambodia, we estimated amounts of nutrient transported by flood and inundation. A local-scale model based on observation and a large-scale model based on the hydraulic phenomenon were used. Amounts of nutrient estimated by the local-scale model was almost same as the amounts of nutrient estimated by the large-scale model. Relationship between the estimated amounts of nutrient and rice production in Cambodia were compared with the relationship between amounts of fertilizer and rice production in Japan. We conclude that the amounts of nutrient transported by flood and inundation are enough to rice production in Cambodia.
