Geoenvironmental approach to restoration of agricultural land damaged by tsunami

In this study a geo-environmental approach was used for the restoration of the farmed land which was damaged by salinity, due to tsunami water water in the pacific coast of Tohoku region in Japan. The mega earth quake that hit on 11th March, 2011 has triggered a Tsunami in the coastal areas of Tohoku region. The huge water severely affected various environmental and geoenvironmental parameters in that area. Soil salinity in the agricultural land has become a great concern for the after disaster geoenvironmental restoration. Various approaches are being tried to get rid of the salinity problem of the agricultural land. In this study, major chemical properties (pH, electrical conductivity) of soil in Rikuzentakata city (one of the most affected areas due to tsunami) were measured in the field test during May and June, 2011. An innovative approach by using compost containing Halo bacteria/salt tolerance bacteria in this area was tested to restore the saline soil. This method can be useful for reducing the excessive salts from the soil. The compost can also provide necessary nutrients to the soil and plant.
