Geoinformatics is application of information technology for study and management of earth resources. The salt affected soils of Gohana were mapped and evaluated using visual interpretation of IRS-P6 satellite false colour composite (FCC) image with ground survey and laboratory analysis. A total of 72 soil samples across the study area were sampled based on the quality of groundwater used for irrigation at four depths (0-15, 15-30, 30-45 and 45-60 cm). Long-term irrigation with salt affected water results in soil quality decline. The texture in both normal and salt affected soils was loamy sand to sandy clay loam. |
