摘要：

The standard false colour composite (FCC) print made from bands 2, 3 and 4 of Landsat-TM data at 1:50 000 scale covering part of the Indo-Gangetic plain was interpreted visually following a systematic visual interpretation approach. Based on image elements and their correlation with the ground features, two categories, namely moderately and strongly sodic soils, could be delineated. On Landsat-TM FCC print strongly sodic soils appear as bright as bright white patches with fine texture, while moderately sodic soils are manifested as dull white to strong brown. The delineation thus made, would help the execution of a reclamation programme for sodic soils at district level.
