Abstract
 Detecting Soil Salinity Levels in Agricultural Lands Using Satellite Imagery Track: Agriculture Author(s): Aymn Elhaddad, Luis Garcia Soil salinity is a problem that affects agriculture and reduces yield. Mapping soil salinity is the first step in identifying the magnitude of the problem. To determine the amount of soil salinity, soils samples are collected and analyzed in the lab or by using Electro Magnetic devices (EM38) in the field. Both of these techniques can give good estimates but both of them are time consuming and not practical or economical when evaluating large areas. This research uses satellite imagery to determine the severity of soil salinity and its impact on crop yield. Based on field ground data collection, the multi-spectral data is trained to distinguish between different levels of soil salinity using ArcGIS customization. Based on this information, the image can be classified into several soil salinity classes hence estimating their impact on the crop.
