| 内容記述 | In March 2011, the 2011 off the Pacifi c coast of Tohoku Earthquake and resulting tsunami caused damage to large areas of agricultural land. In Ibaraki Prefecture, 1040 ha of agricultural land was affected, 540 ha of which was damaged not by the tsunami, but by ground liquefaction. Damage due to ground liquefaction in Ibaraki Prefecture was centered at the Nishishiro district of Inashiki City. In that district, rice was planted in paddy fields that, having sustained ground liquefaction damage, could be restored to a plantable condition through emergency measures implemented by farmers themselves. However, salt damage was observed in the paddy rice approximately 1 week after planting. As a result, salt damage in agricultural land where ground liquefaction occurred was periodically investigated in order to understand how farming activities were being affected. From soil chemistry analysis, it became clear that the topsoil contained a number of soil components originating from sand boil deposits. In particular, sand boil deposits contained higher quantities of chloride, sodium, and sulfate than ordinary topsoil, suggesting that the salt content of the deposits was derived from sea water. In many areas where sand boils occurred, paddy rice did not produce ears and sterile plants did not ripen. With extreme differences being found in rice growth between sections of fields where ears of rice emerged and those where they did not — dependent on the boundary of the area where sand boils occurred — harvesting was not performed in paddies where signifi cant sterility rates were seen. Concerns were raised that large differences in rice growth within individual fi elds would lead to decreases in both operating effi ciency and the quality of rice shipments. This investigation has clearly shown that, unlike salt damage caused by the tsunami, salt damage caused by ground liquefaction is characterized by large differences in crop growth within individual fields. |
