【 摘 要 】

The Great East Japan Earthquake on 11 March 2011 caused damage to barley in a paddy field in Inashiki-city, Ibaraki-prefecture. There were 96 spots of boiling sand in the field. The area of boiling sand was 252 m2 in total and it corresponded to 12.6% of the 20 a field. The boiling sand showed a pH ranging from 3.7 to 5.4 and EC from 0.12 to 0.52 mS/cm. The difference in levels became 267 mm in this field. Pool appeared and barley was damaged by wet injury in a hollow place. Barley can grow on the boiling sand with pH adjustment in the pot experiments. It is considered that leveling and pH adjustment allow conduce for succeeding cropping in such fields.
