Use oe aerial photograph for study of soil salinity and landscape relationship in parts of Haryana

In order to know the development of soil salinity and alkalinity in relation to landform, a systematic approach has been adopted by using aerial photo-interpretation techniques followed by field checks. The major land form units identified in the area are (i) alluvial upland (ii) low land (iii) back-swamp areas (iv) remanent horstland (v) interfiuve (vi) abandoned channel (vii) plain undifferentiated and (viii) plain with aeolian activity. salt accumulation is pronounced in landform units (i), (ii), (iii) and (iv) due to configurating slopes and basement ridge control, whereas in landform units (v) and (vi), a patchy distribution of salinity has been found. Landform units (vii) and (viii) are free from this hazard The elements of landscape have controlled the distriburion of salts within each landscape.
