Abstract
With rationalization of the management, the flowing down salt field has occupied the most important position in the brine production in place of the “Irihama” salt field. However, on the components of brine produced by the former, there can not be found any satisfactory data. From this point of view, we analysed the brine of each season produced by several principal salt field and obtained the reference inforemation about salt production on the flowing down system and salt making.
