Many soil survey projects had launched in the 1950s in Japan. As a result, assessment of arable soils revealed the status and problems of soils and the consequent measure for amendment succeeded in soil productivity improvement. Recently, however, the number of soil monitoring sites has decreased conspicuously for several reasons. Continuous soil monitoring is necessary to assess the present soil conditions and to predict a change of soil conditions by different soil management practices. We introduce the outlines of the soil survey and monitoring activity in Niigata prefecture and its outcomes. Furthermore, the authors show a new soil survey style with Personal Digital Assistant (PDA).
