Surprisingly, there is a spring of water in the Tottori Sand Dunes. Considering the elevation, it is clear that this water is not seawater. In addition, the Tottori University Arid Land Research Center has the largest spring in the dune area. There is no precedent for the growth of horseradish in coastal dunes other than this spring. Therefore, we conducted a study to investigate the relationship between the composition of the spring water and the growth factors.
Twenty-six outlets were selected from among the many inlets in this spring area, and weekly measurements of the constituents (air temperature, water temperature, pH,EC,Na+,Ca2+,NO3-) were carried out. Based on these results and topographical considerations, it was concluded that rainfall has a strong influence on this spring, and that the pathway of rainfall inflow differs depending on the location of the spring in the Drylands Research Institute. In addition, the difference in the composition of the water from the spring made it clear that this spring is a suitable place for the growth of wasabi.
In the future, we would like to investigate the subsurface structure around the spring and study the groundwater flow paths in each area.
