Fukushima nuclear power plant damaged by the East Japan Great Earthquake caused radioactive fallout around the Tohoku region. Because radioactive fallout was positively charged, it was reported to be adsorbed to soil surface. Surface soil scraper and deep plowing would be, therefore, effective for the removal of radioactive materials. However, these scraped surface soils caused another issue for disposal. Therefore in this research project, artificial macropore which imitated the natural soil pores were installed in agricultural soils to transport the radioactive Cesium to deeper profile and adsorb on the mineral soils. Results showed that elution process by Ammonium Sulfate, transport process by artificial macropore and absorption inhibition process by Potassium Chloride were needed for the effective management in agricultural field.
