The purpose of this study is to investigate the sedimentary soil which could be worth using as soil amendment in agricultural field, in the Sameura Dam in Kochi prefecture (SSD). Chingensai (Brassica campestris var. chinensis) were cultivated in the green house soil (GHS), GHS mixed with SSD and SSD only. Sweet corn (Zea mays L.) were cultivated in the upland field soil (UFS) and in the field coating with the SSD on UFS. The growth and yield of the crops were observed, and the chemical analyses of these samples were investigated among these soil plots. Results suggested that SSD could be useful for dilution of nutrients in the range of optimum crop growth in the salt accumulated soil such as continuous green house soil. Furthermore, SSD could be used as soil dressing to the field that have shallow top soil layer, but it is more necessary to examine the physical properties and status of organic matter of treated field soil because the sand content of SSD was high and the total carbon and nitrogen were low.
