Soil salinity assessment research using remote sensing techniques: a special focus on recent research

Abstract Soil salinity is an important environmental problem affecting arid and semi-arid regions. There are direct measures for measuring soil salinity but the conventional methods of assessing soil salinity through chemical analysis is time consuming. With the development of GIS, remote sensing and its popularization in soil science research, the evaluation of soil salinity has become much easier, with the advantage of getting accurate results without tedious sampling. This research addresses the status of various studies done in the international scenario to assess soil salinity and evaluates them. The evaluation is based on the type of articles, geographical region and funding sources. In general, this study will bring out the advantages of remote sensing as an efficient tool for soil salinity related research in the light of current research compared to the contemporary studies in the same field.
