In order to recycle much wood ash back to the forest as fertilizer, modifications of their solubility are necessary. In this study, we evaluated the dissolution properties of stabilized wood ashes by using single batch leaching tests with different leaching times (10 minutes, 1, 3, and 6 hours). Two types of stabilized ashes (distilled water and magnesium lignosulfonate treated type) were compared with control. The both stabilization treatment suppressed the increases of pH (values) of leaching test eluates. In short leaching time, the eluates from the magnesium lignosulfonate type exhibited lowest pH. The elutes from the magnesium lignosulfonate type also exhibited lowest electric conductivity in the short leaching time, but the difference in electric conductivity of elutes with different stabilization methods become smaller as the leaching time increased.
