The three hazardous substances, cadmium, copper, and arsenic, had been determined in Japanese act for an agricultural land. The Japanese government reported the countermeasures for 92.7% of all designated areas have been completed at the end of fiscal year 2015. The risk management for the mine-impacted agricultural land requires the widely applicable countermeasures including continuous implementation of the existing countermeasures, e.g., soil dressing, well-controlled irrigation procedure, maintaining adequate soil pH, and additional introduction of technique recently developed to reduce the concentration of the hazardous substances. In Japan, the phytoextraction of Cd is well-developed phytotechnology that could meet to farmer's benefit. There are two strategies for the Cd phytoextraction to be d...
