| Research Abstract |
The movement of water and nitrate-N in deep layers were studied from the viewpoint of the groundwater quality, the hydrogeology, the chemical property and the biological property for the analysis of the groundwater nitrate-N pollution in the rural area. Those characteristics of the deep soil became clear from the analysis of undisturbed core sample that had been obtained by the geological boring from the soil surface to the bed rock. As for the investigated case including such a deep soil, the result achieved extremely few is expected to cause the clarification of the water and N cycles in a river basin in the future.
